The dryer lint filter is the one appliance maintenance task that most Australians know they should do after every load -- and the one that genuinely matters most from a safety standpoint. A clogged lint filter isn't just an efficiency problem. It's a fire risk, and it's one of the most preventable causes of house fires in homes with a laundry.
What fewer people realise is that the lint filter is only part of the picture. Even when the filter is cleaned after every load, a significant amount of lint bypasses it and accumulates in the vent hose and exhaust duct. That build-up is invisible from inside the laundry, and if it isn't cleared periodically, it creates exactly the same heat retention and fire conditions as a neglected filter.
AtNational Appliance Repairs, we service dryers across Australia, and reduced airflow from lint build-up is one of the most common causes of the dryer faults we see. Here's how to clean both the filter and the vent properly -- and how often each needs attention.
Why Lint Build-Up Is a Safety Issue
Lint is composed primarily of tiny fibres shed from fabrics during drying. Those fibres are extremely flammable. When lint builds up in the vent system and airflow is restricted, heat from the dryer's element or gas burner has nowhere to escape. The internal temperature rises, and if lint is in the right position -- inside the duct, at the exhaust cap, or around the drum -- ignition becomes possible.
Dryer fires are a consistent cause of house fires in Australia. The risk increases sharply when:
The lint filter is not cleaned between loads
The external vent hose is a flexible plastic or foil type that creates internal ridges where lint catches
The vent run is long or has multiple bends, which restricts airflow and accumulates lint faster
The household dries large loads of fluffy fabrics (towels, fleece, pet bedding) that produce more lint
The fix is straightforward maintenance -- but it has to be done consistently to be effective.
Part 1: Cleaning the Lint Filter
How often
After every single load. Not sometimes. Every time.
This is the most important habit in dryer maintenance. Bar none. A clean filter before each load lets air flow through the machine properly. It keeps drying efficient. And it removes the primary fuel source for a dryer fire. That last one matters.
To clean the lint filter:
Find the filter. On most Australian dryers, it is in a slot in the door opening, on top of the machine, or just inside the drum. Slide it out or lift it out.
Peel the lint off with your fingers. Throw it away. Usually it comes off as one fluffy sheet.
Hold the filter up to the light. You should be able to see through the mesh clearly. If it still looks blocked, do the deeper wash below.
Slide the filter back in before you start the next cycle.
Washing the filter: Every three to six months
Another thing that most people don’t know: dryer sheets can leave a waxy residue on the filter mesh. You cannot see it. But it builds up over time and blocks airflow. Even when the filter looks perfectly clean.
To remove that residue:
Wet the filter under warm running water.
Put a small amount of dish soap on it. Gently scrub both sides with a soft brush or an old toothbrush.
Rinse thoroughly. Keep rinsing until water flows freely through the mesh, not just pooling on the surface like a puddle.
Let the filter dry completely before you put it back. A damp filter creates moisture issues inside the drum. Leave it on the bench to air-dry or dry it with a cloth.
Part 2: Cleaning the Vent Hose and Exhaust Duct
How often: At least once a year; every six months for heavy-use households
Even with the lint filter cleaned after every load, up to 25% of lint produced per cycle passes through the filter and into the vent system. Over twelve months of regular use, that accumulation becomes significant.
Signs the vent needs cleaning:
Clothes taking noticeably longer to dry than they used to
The dryer or the laundry room feels excessively hot during a cycle
A burning or musty smell during operation
Lint visible around the external vent opening
The dryer's thermal cut-out tripping repeatedly (a safety feature that activates when internal temperature exceeds a safe threshold)
Any of these signs warrant immediate cleaning of the vent system -- don't wait for the scheduled annual clean.
What you'll need:
A vacuum with a narrow attachment or hose
A dryer vent cleaning brush kit (a long, flexible rod with a brush attachment, available at hardware stores)
A screwdriver (to disconnect the vent hose if needed)
Steps:
Disconnect the dryer from power before doing any vent work. For gas dryers, ensure the gas supply is also off.
Pull the dryer away from the wall to access the vent hose at the rear.
Disconnect the vent hose from the dryer outlet. Most connections use a clamp or simply press-fit onto the outlet -- check your model.
Vacuum inside the vent outlet on the dryer itself. Use the narrow attachment to remove any accumulated lint from inside the duct outlet.
Use the flexible brush to clean inside the vent hose from both ends -- push the brush through from the dryer end, then work from the wall end if the hose is long. Rotate the brush as you work to dislodge lint from the walls of the hose.
Vacuum loose lint from inside the hose after brushing.
Check the exterior vent cap where the hose exits the building. Remove any lint packed around or behind the flap. A blocked exterior cap is a common cause of restricted airflow -- the flap should open freely when the dryer runs and close when it's off. A stuck or bent flap also allows birds or insects to nest in the duct during quieter periods.
Reconnect the hose securely and push the dryer back into position, ensuring the hose isn't kinked or crushed behind the machine.
Vent Hose Types: What to Use and What to Avoid
Hose Type
Risk Level
Notes
Rigid metal duct
Lowest
Best option for long runs; smooth interior minimises lint catch points
Semi-rigid metal (aluminium)
Low
More flexible than rigid; still smooth interior; suitable for most residential installs
Flexible foil (metalised plastic)
Higher
Internal ridges catch lint; can collapse; most fire safety guidance recommends against it
Flexible plastic (white vinyl)
Highest
Flammable; not suitable for dryer venting; not compliant with Australian standards
If your dryer currently uses a flexible plastic or foil vent hose, replacing it with semi-rigid or rigid metal is a meaningful safety upgrade. It also improves airflow and reduces how frequently you'll need to clean the duct.
Condenser and Heat Pump Dryers
Condenser dryers and heat pump dryers don't vent to the outside -- they manage moisture internally. They still have lint filters that need cleaning after every load, and many also have a secondary filter (sometimes called a fluff filter or heat exchanger filter) that needs periodic cleaning.
Check your model's manual for the secondary filter location -- on many condensers it's a panel accessible from the front base of the machine, and it accumulates lint that bypasses the primary filter. Neglecting the secondary filter on a condenser dryer causes the same overheating and performance issues as a blocked vent on a vented model.
FAQ
How do I know if my dryer vent is blocked?
A few reliable signs. Clothes take way longer to dry than they used to. The laundry room gets excessively hot during a cycle. Or you notice a burning smell. Here is a quick check you can do. Disconnect the vent hose from the wall. Run a short cycle. If the dryer performs noticeably better with the hose disconnected, the blockage is in the duct run. Not the machine itself.
Can I clean the dryer vent myself or do I need a professional?
Depends on your setup. For most residential installations with a short, accessible vent run, the DIY process is straightforward. You can handle it. For very long runs, multiple bends, or vents that go through the roof or a tricky location, consider a professional duct cleaning service. Once a year or every two years.
My dryer keeps cutting out mid-cycle. Is this related to lint?
Very likely. Most dryers have something called a thermal cut-out. It is a safety thermostat that trips when the internal temperature gets too high. A restricted vent or a clogged lint filter causes exactly that kind of overheating. Clean the filter and the vent. Then test again. If it still trips with a clean filter and clear vent, the thermal cut-out itself may have degraded and needs replacement. That is a repair we handle. All major brands.
How often should I replace the dryer lint filter entirely?
You probably do not need to replace it unless it is damaged. Check the mesh. Is it torn? Is the frame warped or cracked? A damaged filter lets lint bypass into the drum and the vent system. So inspect it periodically. Replace it if you see damage. Most brands have replacements available through appliance spare parts suppliers.
Is it safe to run the dryer while I am out of the house or asleep?
Fire safety guidance is pretty consistent on this. Do not do it. The dryer should only run when an adult is home and awake. Most dryer fires happen when the machine is running unattended. Use a timer or a smart plug to schedule loads for when you are home. That is a practical way to make it a habit.
Conclusion
Cleaning the lint filter after every load takes ten seconds and eliminates the single biggest dryer fire risk in most Australian homes. Washing the filter mesh every few months and clearing the vent duct annually completes the maintenance picture.
If your dryer is taking too long to dry, running hot, or tripping mid-cycle even after cleaning, there may be a mechanical fault underlying the problem. We atNational Appliance Repairs service dryers across Australia -- call 1300 434 380 and our technicians will diagnose the issue fast.
Chicken is the most consumed meat in Australia, and leftover cooked chicken is a staple of weeknight meal planning across the country. It goes into sandwiches, salads, pasta, fried rice, and soup -- but only if it's still safe to eat. The question of how long cooked chicken lasts in the fridge comes up more than almost any other food storage question, and the answer matters because chicken is one of the higher-risk proteins when it comes to food-borne illness.
Here's the definitive answer, with the reasoning behind it.
The Short Answer
Cooked chicken keeps for 2-3 days in the fridge, sealed, at 4°C or below. The Australian Chicken Meat Federation is clear on this, and FSANZ guidelines back it up. Some sources push it to 3-4 days -- but two to three is the number, one day for minced.
Chicken doesn't keep as long as most cooked meats because of what naturally lives on it. Salmonella and Campylobacter are part of chicken gut flora and can survive on the raw meat surface. Cook it to the right internal temperature and most are destroyed -- but not always all of them. The fridge slows what's left, it doesn't finish the job.
Listeria is a separate concern. It grows slowly even in the cold, and the illness it causes -- listeriosis -- can be debilitating for healthy adults and genuinely dangerous for people who are pregnant, elderly, or immunocompromised. The Australian CDC recommends this group eat cooked chicken within one day or freeze it.
Why 2-3 Days, Not Longer
Keeping chicken at or below 4°C slows bacterial growth a lot -- but it doesn't stop it. Any bacteria that survived cooking, or got in during handling, keep multiplying in the fridge. Slowly, but steadily. By day three or four, the numbers can be high enough to make you sick, and the chicken will look and smell completely normal the whole time.
That's the thing about food-borne illness: the food rarely tells you. Salmonella, Campylobacter, Listeria -- none of them change how chicken looks, smells, or feels. The time limit exists because your senses aren't enough.
How to Store Cooked Chicken to Maximise Its Safe Life
Cool it down first -- but quickly
Once the chicken stops steaming, it goes in the fridge. The Australian Chicken Meat Federation puts the limit at two hours at room temperature -- less if you're cooking in a Brisbane or Adelaide kitchen in summer. To move cooling along: break big pieces into smaller ones, spread them across a shallow container instead of stacking, and put it in the fridge uncovered until it hits fridge temperature. Then put the lid on.
Watch out for the whole roast sitting on the counter while the meal winds down. It seems fine, but by the time it makes it to the fridge, the outer meat may have been warm long enough to rack up real bacterial growth.
Use a sealed container
Cooked chicken stored uncovered in the fridge can absorb odours from other foods and is exposed to cross-contamination risk from raw foods stored nearby. An airtight container protects both quality and safety.
Store on the top shelf, above raw meat
In a correctly organised fridge, cooked and ready-to-eat food sits on the top shelf, above raw meat and poultry on the bottom shelf. Drips from raw chicken stored above cooked food are a direct contamination pathway.
Label with the date
If you meal prep or regularly batch-cook chicken, label containers with the date stored. The 2-to-3-day window starts from the day it was cooked and refrigerated, not from when you last opened the container.

Can You Freeze Cooked Chicken?
Yes. Freezing cooked chicken is the right call if you've cooked more than you'll eat in two to three days. Cooked chicken can be frozen for two to six months with good quality retention, according to FSANZ guidelines. Beyond that, it remains safe to eat (bacteria cannot multiply at -18°C) but quality -- texture, flavour, moisture -- degrades noticeably.
Freeze cooked chicken in portions rather than as a whole batch. Label each container with the date and contents. Thaw in the fridge overnight rather than on the bench; defrosting at room temperature takes the chicken through the danger zone while the outside is thawing.
Chicken that has been thawed in the fridge can be refrozen only if it hasn't risen above 5°C and was thawed for no more than 48 hours.
Signs Cooked Chicken Has Gone Off
As noted, you cannot rely on sensory tests alone -- but these signs are a clear signal to discard:
A sour, sulphurous, or otherwise off smell when the container is opened
A slimy or sticky texture on the surface of the meat
Visible mould or discolouration (greyish or greenish patches)
A noticeably different texture from when it was freshly cooked
If the chicken has been in the fridge for three days and you're uncertain, err toward discarding it. The cost of wasted chicken is considerably less than the cost of food poisoning.
Reheating Cooked Chicken Safely
When reheating stored cooked chicken, the internal temperature needs to reach 75°C throughout to kill any bacteria that have developed during storage. A meat thermometer is the only reliable way to confirm this. Reheating to 75°C also applies after microwaving -- stir partway through the cycle and check the temperature in the thickest part of the meat.
Chicken should only be reheated once. Repeated cooling and reheating cycles give bacteria additional opportunities to multiply during the gradual temperature changes.
FAQ
Is cooked chicken still safe after 3 days in the fridge?
Two to three days is what the Australian Chicken Meat Federation recommends. Day three can still be okay if the chicken was handled well, cooled fast, and kept sealed below 4°C. After that, there's no way to judge safety by sight or smell, and the bacterial risk gets real. When in doubt, throw it out.
Can I eat cooked chicken cold, or does it need to be reheated?
Cold chicken from the fridge is fine -- good in sandwiches, salads, wraps -- as long as it's within 2--3 days and was stored right. Whether you reheat is up to you and the dish. If you do, 75°C all the way through.
Why does cooked chicken only last 2--3 days when cooked beef lasts longer?
Poultry naturally carries more Salmonella and Campylobacter than red meat, and those bacteria don't stop at the fridge door -- they just slow down. Beef, lamb, and pork whole cuts go 3--5 days because the bacterial load and surface area are different.
My fridge is set to 2°C -- does cooked chicken last longer?
It helps. Colder temps slow bacterial growth further, and running at 2--3°C is worth doing. But the 2--3 day window is built around normal home conditions for a reason -- a slightly colder fridge won't make day four safe.
What happens if I eat cooked chicken that's been in the fridge for 4 or 5 days?
Maybe nothing. Maybe a rough couple of days. You can't assess the risk from appearance or smell -- it depends on the bacterial load going in, how fast it was chilled, how your fridge performed, and how your body handles it. The odds get worse with each extra day. Just don't.
Conclusion
Cooked chicken lasts two to three days in the fridge -- one day for minced chicken, and one day for anyone who is pregnant, elderly, or immunocompromised. If you can't use it in that window, freeze it promptly and thaw it in the fridge when needed.

The second fridge is a Perth institution. It lives in the garage, it holds the overflow from the main fridge, the drinks for the weekend, the extra meat from the bulk butcher run. It works quietly all year -- until summer arrives.
Perth's climate is uniquely brutal on refrigeration equipment. The city records more days above 35°C than any other Australian capital. During the worst of the summer days, in places like garages, sheds, and outdoor laundries, temperature can hit as high as 45°C. Meanwhile, a standard domestic refrigerator is designed and tested to operate in ambient temperatures up to about 32°C -- during summer, that fridge may be running in conditions 10 to 15 degrees beyond its designed range every single day of the season.
The result is predictable: compressors run constantly, components wear out faster, and the fridge either stops cooling properly or breaks down entirely. We atNational Appliance Repairs see a sharp increase infridge and freezer repair calls across Perth every summer, and a significant share of them are second fridges that have finally given up under the strain.
Here's what's actually happening, and how to keep yours running.
Why Heat Kills Fridges
A refrigerator works by moving heat from inside the cabinet out. It does this through the compressor pumps, which move refrigerants through the system via a series of tubes. This refrigerant soaks up the heat and releases it through the condenser coils either at the back or the base of the unit.
The problem in a hot garage is simple. There is nowhere for that heat to go. When the outside air is 43°C, the condenser is trying to dump heat into air that is already extremely hot. The physics works against you. The compressor has to work harder to maintain the temperature difference. It runs longer. It generates more heat itself. And the internal temperature of the fridge creeps upward anyway, even with the compressor running flat out.
At a certain point, the compressor simply can't keep up. The freezer starts to soften. The fridge section climbs above safe temperatures. Food spoils. If the compressor runs continuously for extended periods in this state, the motor windings overheat, causing premature compressor failure -- an expensive fault that in many cases means the appliance is uneconomical to repair.
The Tropical Rating: The Single Most Important Spec
Not all fridges are built for the same conditions. Appliance manufacturers use climate class ratings to indicate the ambient temperature range an appliance is designed for.
Class N (Normal): 16--32°C
Class ST (Sub-Tropical): 18--38°C
Class T (Tropical): 18--43°C
Class SN (Sub-Normal): 10--32°C
A standard domestic fridge sold in Australian appliance stores is typically Class N or SN -- designed for indoor, climate-controlled use up to 32°C. In a Perth garage in summer, it's operating outside its rated range every hot day.
A tropical-rated compressor handles up to 43°C ambient. Without one, your fridge will run continuously in summer, wear out the compressor prematurely, and struggle to hold temperature. If your garage second fridge was never specified for tropical use, the heat stress you're seeing is a design mismatch, not a fault.
When buying a second fridge or upright freezer destined for a Perth garage, check the climate class on the specifications sheet or ask the retailer directly. Tropical-rated models are available, though they may cost more than the standard range.
Location and Ventilation
The placement of a second fridge in a garage has a disproportionate effect on how hard it has to work.
Don't place the fridge against a wall with no rear clearance. The condenser coils need airflow to dissipate heat. Fridges pushed flat against the wall trap heat behind them and can't cool efficiently.
Keep at least 50--100mm clearance at the back and sides. Check your model's manual for the specific clearance recommendation.
Avoid positioning the fridge where direct sunlight hits it. Even filtered afternoon sun through a west-facing garage roller door significantly raises the fridge's surface temperature and adds to the work the compressor is doing.
A garage with some airflow fares much better than a sealed one. If the garage has vents, keep them clear. If it's fully sealed and you're in Perth, the internal temperature on a 42°C day can exceed the outdoor ambient by several degrees, pushing the fridge even further beyond its safe operating range.
Avoid positioning the fridge near the hot water system or other heat-generating appliances. The surrounding heat load all adds up.
Maintenance That Matters in a Perth Garage
Clean the condenser coils
Condenser coils coated in a centimetre-thick layer of dust and garage grime can't dissipate heat. In a kitchen, this process can take months to years, but in a garage? May take only a month or two, perhaps even weeks.
You can locate the condenser coils at the back or underneath the cabinet, behind a kickplate (if you're unsure, you can check the manual for the unit -- if you don't have it, check the model number in the back and search for the manual online). Unplug the fridge, and use a vacuum with a brush attachment to sweep off the dust from the coils. It'll also be a good idea to use a clean, dry cloth to wipe down any surface you see. Even though it takes no more than 15 minutes and some elbow grease, this step can drastically reduce compressor running time and the rate of heat buildup in the summer.
Aim to clean condenser coils at least once before summer, and again mid-season if your garage is dusty.
Check door seals
A door seal that isn't creating a proper airtight closure lets warm outside air enter the fridge constantly -- the compressor has to continuously compensate for it. In summer heat, the effect is amplified.
Test the seal by closing the door on a piece of paper or a banknote. If you can slide it out with no resistance, the seal has lost its grip and warm air is leaking in. Replacement door seals are available for most common brands and are an inexpensive fix.
Set the thermostat correctly
In summer, the thermostat setting may need to be adjusted to maintain a safe internal temperature. Food should be kept at or below 4°C in the fridge section and at 0°C or below in the freezer. A basic appliance thermometer costs very little and removes the guesswork. Don't crank the thermostat to maximum without knowing the actual internal temperature -- running unnecessarily cold adds to compressor load.
Watch for early warning signs
The compressor runs constantly with very little quiet cycling time
The sides or back of the fridge are significantly hotter than usual
The interior is noticeably warmer than the thermostat setting suggests
Ice cream or other frozen items are softening
The fridge is making new or louder noises
Any of these in peak summer heat warrants attention. A compressor that's been running hard and hot for weeks is under significant stress, and catching the signs early is far better than waiting for a full breakdown.
When to Write Off a Second Fridge
Perth summer heat accelerates wear on ageing compressors. If the second fridge is over ten years old and is showing significant cooling problems during the hottest weeks, the honest assessment is often that repair costs may not be justified -- particularly if the compressor itself is failing.
A compressor replacement on an older second fridge can cost several hundred dollars once parts and labour are included. If the fridge is already old, replacing it with a tropical-rated model suited to a garage environment often makes more long-term sense than repairing a standard model that will face the same heat stress next summer.
That said, many second fridge faults in summer are not compressor failures -- they're dirty coils, failed door seals, or thermostat problems, all of which are inexpensive to fix. A technician's diagnosis will quickly identify whether the repair is worthwhile.
Quick Reference: Perth Summer Second Fridge Checklist
Confirm the fridge's climate class -- tropical-rated for garage use
Clean condenser coils before summer starts
Check door seal integrity
Ensure 50--100mm rear and side clearance for airflow
Position away from direct sunlight and other heat sources
Monitor internal temperature with a thermometer in December--February
Watch for continuous compressor running as an early warning sign
FAQ
Can I keep a standard fridge in a Perth garage year-round?
Winter is fine, but you’re pushing it in a Perth summer. A standard Class N fridge is not built for 40-degree garages. It might survive if the garage has good airflow or no sun, but it’ll wear out faster.
What is a tropical-rated fridge and where can I buy one in Perth?
Class T fridges can run in ambient temps up to 43°C. Several brands make them. Ask the retailer or check the spec sheet to see if the model is rated. Chest freezers are often Class T – they’re good option for a Perth garage.
My second fridge is working but everything feels warmer than usual. Do I call a technician?
Clean the coils and check the door seals first. If that does not help and it is still warm in summer, call a tech. Low refrigerant or a struggling compressor are both fixable for relatively cheap if you catch them early.
Would an insulated garage make a big difference to my second fridge?
Big time. An insulated garage plus reverse-cycle AC keeping it below 30°C will keep the fridge running like it is indoors. Aside from it consuming less energy and have a longer lifespan, you can also use the garage as a gym or a workshop.
How often should I service the second fridge?
You should clean the coils before the summer hits at the very least. If the fridge is over five years old and in a hot garage, get a tech to check it once a year to check on everything – from refrigerant and compressor to seals.
Conclusion
The second fridge is too useful to lose every few years to preventable heat damage. The right appliance in the right position, with clean coils and a working door seal, handles a Perth summer far better than a standard indoor fridge pushed into conditions it wasn't designed for.

Your appliances do not need a direct lightning strike to die. Just a strike somewhere in the neighbourhood on a power line. The voltage spike travels down the grid, through your switchboard, along your wiring, and into whatever is plugged in. Milliseconds.
The repair bill? Not milliseconds.
South-east Queensland storm season is October through March. Intense storms. Lightning. Hail. Damaging winds. The kind of power events appliance techs in Brisbane know well. National Appliance Repairs sees a spike in fridge, washing machine, and oven repair calls after every major storm. Most of it could have been prevented.
What a Power Surge Actually Does
Appliances are built for stable voltage. In Australia, 230 volts, plus or minus 10%. A surge is a sudden spike above that. Sometimes thousands of volts for a fraction of a second.
That spike can fry modern appliances. The three most vulnerable parts: the control board, the compressor (fridges and ACs), and the motor drive electronics (washing machines and dishwashers). Control boards are the weakest link. They run on very low voltage. A spike that a motor ignores will kill a control board dead.
Two storm-related events cause most surge damage:
Lightning nearby: A strike on power infrastructure sends a massive voltage surge down the grid, which can kill multiple appliances at once.
Power comes back after an outage: Energex re-energises a section of the grid to restore service. However, for a very brief moment after the switch is flipped, the returning current can hit higher than normal before it settles. Appliances left plugged in and switched on take the full brunt of that surge. That is why post-blackout faults are so common -- the damage does not show up until the power is restored.
Which Appliances Are Most at Risk
Not all appliances are equally vulnerable. The more electronics an appliance contains, the more exposed it is.
High risk:
Refrigerators and freezers -- control boards manage compressor cycling, defrost timers, and temperature sensors; all are surge-sensitive
Washing machines and dishwashers -- modern units have sophisticated control boards managing motor drives, water levels, and cycle timing
Combination microwave ovens -- dense electronics in a compact unit
Moderate risk:
Electric ovens with digital control panels
Dryers with electronic moisture sensors
Air conditioners
Lower risk:
Older appliances with purely mechanical or analogue controls (no circuit board)
Simple resistive-load appliances (a basic toaster element, for example)
The clear pattern: the newer and more digitally controlled an appliance is, the more it stands to lose from a surge.
Understanding Surge Protection
Standard power boards? They do nothing.
This is the thing people get wrong all the time. A standard power board--even a nice one with a switch and six outlets--is just a multi-socket adapter. That is it. It has no protection. A surge comes in, it goes straight through to every appliance you have plugged in.
A real surge protector has MOVs inside. Metal oxide varistors. Fancy name, simple job. They absorb excess voltage and divert it safely to earth. You will see them rated in joules. That number is the total energy the device can absorb over its lifetime. More joules means more protection.
Here is what you should look for:
Basic stuff such as lamps and phone chargers: 500 to 1,000 joules is fine.
Computers, TVs, home office gear: Go 1,000 to 2,000 joules.
Fridges, washing machines, dishwashers: This is different. Standard strip protectors may not handle the big current surge when a motor kicks on. Look for purpose-designed appliance surge protectors.
Now, here is the catch. MOVs wear out. Every surge they absorb degrades them a little. A surge protector that took a significant hit might look brand new but offer zero protection on the next storm. Better quality units have an indicator light to tell you the protection is still working. But honestly, replace them every three to five years. Or after any major storm event. Cheap insurance.
Whole-house surge protection
The gold standard is a whole-house surge protection device. A licensed electrician installs it at your main switchboard. It catches surges at the point of entry before they can spread to your internal circuits. Then you still use point-of-use protectors for your really sensitive stuff. If you have multiple valuable appliances in your home, it is worth the investment.
Australia has a standard for this--AS/NZS 1768. It covers lightning and surge protection. But here is the thing. Surge protection is not mandatory. It is up to you to decide your risk and install what makes sense. If you live in a storm-prone part of south-east Queensland, the risk is real.
Protecting Appliances Before the Storm
Action
What It Does
Install point-of-use surge protectors on fridge, washing machine, dishwasher
Absorbs voltage spikes at the appliance level
Install whole-house surge protector at switchboard
First-line defence before surges reach internal circuits
Unplug sensitive appliances during severe storms
Eliminates surge risk entirely while unplugged
Check surge protector indicator lights are still active
Confirms protection circuitry hasn't been depleted
Replace surge protectors every 3--5 years
Prevents false confidence from depleted MOVs
Unplugging appliances during a severe storm warning is the most reliable protection available. It is inconvenient, but it is the only way to guarantee a surge cannot reach the appliance. For a fridge or freezer, brief unplugging during a storm is far less disruptive than a damaged compressor.
If you're leaving home during storm season, consider unplugging non-essential appliances before you go.
Signs of Surge Damage After a Storm
After power is restored following a Brisbane storm, inspect appliances before assuming all is well. Surge damage can manifest immediately or appear over days as stressed components begin to fail.
Here are a few signs to watch for:
An appliance that was working before the outage now doesn't start
A fridge or freezer that runs (compressor sounds normal) but doesn't cool
Washing machine or dishwasher that powers on but won't begin a cycle, or shows error codes it didn't show before
A burning or plastic smell from the rear of any appliance
A digital display that is scrambled, unresponsive, or showing unusual readings
An oven that won't reach temperature, or whose timer/clock has reset and won't respond
If multiple appliances were affected simultaneously, a significant surge event is very likely the cause. A technician's report documenting the nature of the fault will support any insurance claim for surge damage.
Insurance and Surge Damage
Surge damage caused by a lightning strike or storm event is generally covered under home and contents insurance policies as a listed peril. However, the policy wording matters -- some policies distinguish between direct lightning strikes and indirect grid surges, and coverage may vary accordingly. Check your Product Disclosure Statement.
Document everything: photograph affected appliances, note when the storm occurred and when symptoms appeared, and arrange a technician's assessment promptly. An itemised report stating the likely cause of the fault strengthens any claim considerably.
FAQ
Do I need a surge protector if my home has a modern switchboard?
Short answer: yes. A modern switchboard with circuit breakers and RCDs is great. It protects you from overloads and earth faults. But it does absolutely nothing for voltage spikes. Circuit breakers interrupt current flow. They do not absorb fast transient surges. You need point-of-use surge protectors as an extra layer. They work alongside your switchboard, not instead of it.
Can a fridge survive a power surge if I switch it off at the power point?
Yes. If you switch it off at the wall socket, no current can flow. The surge cannot get to the internal electronics. Switching off at the wall--not just pressing the appliance's own power button--is really effective protection during a severe storm. Takes two seconds.
My appliance seemed fine after the storm but stopped working two weeks later. Can that still be surge damage?
Absolutely. Surge damage can show up two ways. One, immediate failure. The appliance dies right then. Two, partial damage. Something gets weakened but keeps working for a while. Then it fails progressively over days or weeks. If your appliance failed in the weeks after a major storm and there is no other obvious cause, surge damage should be on the list of suspects.
Does a surge protector work for a fridge or washing machine, or only for smaller devices?
Standard power board surge protectors are designed for lower-wattage stuff. Phones, computers, TVs. They may not handle the inrush current of a fridge or washing machine motor kicking on. You can buy purpose-designed surge protectors for large appliances at electrical and hardware stores. Just check the wattage rating before you plug your fridge into one.
Does unplugging the fridge during a storm risk damaging it when I plug it back in?
No, you are fine. Modern fridges have built-in time-delay protection on the compressor. Briefly unplugging and replugging is not harmful. Just give it three to five minutes after you plug it back in before the compressor tries to restart. That lets the refrigerant pressure equalise. Reduces stress on the system. The fridge will handle the rest itself.
Conclusion
Brisbane's storm season is a predictable annual event, not an occasional surprise. Treating surge protection the same way you'd treat smoke detector testing -- a routine part of home maintenance done before summer arrives -- keeps your appliances safe through the worst the season brings.

You know the smell. Open the fridge door and it hits you before you even see what is wrong. It creeps up on you, getting stronger each day you ignore it. A spill you missed. Fruit gone soft at the back. Leftovers pushed behind something and forgotten. The fridge gets used every day, and without regular attention, it becomes a graveyard of every food mistake from the past month.
The good news? A thorough clean takes less than an hour, uses products already in your kitchen, and makes a genuine difference to both smell and hygiene. AtNational Appliance Repairs, we service fridges across Australia, and a clean, well-maintained fridge runs more efficiently and lasts longer than a neglected one.
Why Fridges Smell
Odours come from a handful of consistent sources:
Spoiled food: Obvious one. Rotting vegetables, meat that has turned, mouldy leftovers, sauces that have been there since who knows when. Get the source out and the smell usually goes with it.
Spills that soaked into shelving or seals: This one tricks people. You spill something--meat juice, dribbled fruit juice, yoghurt that overflowed. You wipe it up. Looks clean. But liquid seeped into crevices and into the folds of the door seal. Bacteria are still in there producing odour. Wipe-down is not enough.
Cross-contamination of smells: Strong foods like blue cheese, fish, cut onion, garlic-heavy leftovers. They release volatile compounds. Those compounds absorb into the plastic shelving and drawers over time. The smell sticks around even when the food is gone.
Mould in the drain: Most fridges have a small drainage hole at the back of the interior. It channels condensation down to an evaporation tray underneath. That drain can clog with debris. Then mould grows. You get a persistent damp smell that never quite goes away.
The evaporation tray: Underneath most fridges, there is a shallow tray. It collects the condensation draining from inside. Designed to evaporate passively. But if it fills up with liquid and old debris instead of drying out, it becomes a smell source itself. Worth checking if you have ruled out everything else.
What You'll Need
Bicarbonate of soda (baking soda)
White vinegar
Warm water
Mild dish soap
Microfibre cloths
An old toothbrush
A small bowl or open container (for ongoing odour absorption)
Step-by-Step: How to Clean a Fridge
Step 1: Empty the fridge and assess the contents
Take everything out. Put perishables in an esky or a cooler while you work. You are going to be pulling out all the shelves and drawers, so this takes a bit of time.
Now go through every single item. Check use-by dates. Look at the produce. Smell anything that seems questionable. Anything off goes straight in the bin. This is the most important step. I cannot stress this enough. No amount of scrubbing and wiping will fix the smell if the source is still sitting in there.
Step 2: Remove shelves and drawers
Most fridge shelves slide out or lift free. Glass shelves often have a little lip that needs to be tilted slightly before they clear the rails. Crisper drawers usually lift and pull out. If something is not coming out cleanly, check your fridge manual. Forcing it can crack glass shelves.
Wash the removed parts in the sink with warm water and dish soap. Got stuck-on residue? Make a paste of bicarbonate of soda with a tiny bit of water. Use an old toothbrush to apply it. The paste loosens dried spills without scratching the surfaces.
One warning. Do not put cold glass shelves directly into hot water. Thermal shock can crack them. Let them come to room temperature first if your fridge was running cold.
Step 3: Wipe the interior
Mix 15ml of bicarbonate of soda per litre of warm water. That is the recommended concentration for fridge cleaning. Bicarb neutralises both acidic and alkaline food odours. And it leaves no chemical residue that could affect how your food tastes.
Wipe every surface. Back wall, side walls, the roof inside, and the floor. Pay special attention to the channels where the shelves sit. Those channels collect drips that dry into sticky residue over time.
For stubborn stains, use a little undiluted white vinegar. Let it sit for two or three minutes before wiping. The acetic acid breaks down dried food residue and kills mould spores at the same time.
Step 4: Clean the door seal
The rubber gasket around the door. Most overlooked part of fridge cleaning. Its folds trap liquid, crumbs, mould, and dried spills. And it is a significant source of odour.
Pull back each fold of the seal. Wipe with a cloth dampened in your bicarb solution. See mould spots--usually black or green? Use a toothbrush dipped in undiluted white vinegar. Scrub until the discolouration lifts.
Here is an extra benefit. A clean, flexible door seal creates a better airtight closure. That improves the fridge's energy efficiency and temperature consistency. So you save a bit on power too.
Step 5: Clear the drain hole
At the back of the fridge interior, usually behind or beneath the back panel, there is a small drainage hole. It can block with food debris. When that happens, water pools inside and mould grows. Use a toothpick or a thin pipe cleaner to clear any blockage. Then pour a small amount of warm water carefully into the hole to flush the channel.
Step 6: Dry everything and reassemble
Wipe the interior with a clean, dry cloth before you put the shelves and drawers back in. Moisture left inside can contribute to new odours. Replace the shelves and drawers. Reload the fridge. And if you are uncertain about anything you put aside, bin it. Do not take chances.
Stopping Smells from Returning
Open container of bicarb
Take a small ramekin or a jar with the lid off. Put a few tablespoons of bicarbonate of soda in it. Stick it at the back of the fridge. Bicarb does not just cover up smells. It reacts with odour molecules chemically and neutralises them. Replace it every three months. After that, it is saturated and not doing much.
Use airtight containers
Uncovered bowls, loosely wrapped leftovers, cut fruit sitting out – all these release smelly compounds all the time. Those compounds absorb into the plastic shelves and walls. Switch to sealed containers and you cut way down on smells building up in the first place.
Regular quick wipe
See a spill? Wipe it. Right then. Takes two minutes. That two minutes prevents the kind of build-up that forces you to do a full deep clean later. Keep a cloth or paper towels within reach of the fridge. Once it is easy, you will actually do it.

When Cleaning Doesn't Solve the Problem
If the fridge still smells after a thorough clean with the steps above, a few less obvious causes are worth checking:
The drain tray under the fridge: Pull the fridge out and check at the bottom of the unit – you’ll find the shallow tray that’s put there to catch evaporation. If you don’t have a habit of cleaning it, after years of catching drip residue, it can be very dirty. Remove, clean thoroughly with hot soapy water, and replace.
Mould behind the back panel: In older fridges, mould can grow in the drain system or behind the internal back panel. If the smell is damp and musty, definitely check and see if you’ve got an infestation.
Fridge not reaching temperature: If the fridge interior is consistently warmer than 4°C, food will spoil faster and release bad odors in your fridge. An appliance thermometer will confirm whether the fridge is running at the correct temperature. If it isn't, the cause may be a failing seal, a blocked evaporator, or a compressor issue.
If the fridge is running warm and a full clean hasn't resolved persistent odours, ourfridge repair team can diagnose what's going on. We service all major brands across Sydney, Melbourne, Brisbane, Adelaide, and Perth.
FAQ
What is the best natural deodoriser for a smelly fridge?
Bicarb. Hands down. Leave an open container at the back of the fridge. Replace it every three months. That is your ongoing defence. Now, if you have cleaned the fridge and the smell is still there, activated charcoal is stronger. It absorbs a wider range of odour compounds. You can find it at health food stores or hardware places.
How do I get rid of the smell of rotten meat in a fridge?
First, get the source out. Then clean the whole interior thoroughly with a bicarb solution. Once that is done, wipe the affected area with undiluted white vinegar. Leave the fridge door open for about 30 minutes to let it air out. Put a fresh open container of bicarb inside. Then wait 24 to 48 hours. That usually does it. For really bad cases--a small bowl of freshly ground coffee left in the fridge overnight is surprisingly effective.
My fridge smells even though everything inside is fresh. Why?
Check three things people often miss. The door seal. Debris and mould hide in those folds. The internal drain hole. It clogs and grows mould. And pull the fridge out from the wall to check the evaporation tray underneath. That tray collects condensation. If it fills with gunk, it stinks. Those three spots cause most persistent odours when the food is not the problem.
Should I turn the fridge off when cleaning it?
Quick wipe-down? No need. Full deep clean where you are pulling out all the shelves and scrubbing everything? Turn it off. If you leave the door open for a long time with the fridge running, the compressor works hard trying to cool down the warm air rushing in. Switch it off for the clean. Turn it back on when you are done.
How often should I fully clean my fridge?
If you use your fridge heavily, once a month is ideal. Full clean. Shelves out, drawers out, interior wiped, seal cleaned. Combine that with wiping spills as soon as they happen and checking for expired food once a week. Do that and odours never really get a chance to establish themselves in the first place.
Conclusion
A fridge that smells is nearly always a fridge that needs cleaning, not replacing. The bicarb-and-vinegar method costs almost nothing, avoids harsh chemicals near food surfaces, and leaves the interior genuinely clean rather than just masked with a fresh scent.
If the smell persists after cleaning, or if you notice the fridge isn't maintaining a safe temperature below 4°C, the problem may be mechanical rather than a cleaning issue.

Fresh milk doesn't last long, and a lot of it gets tipped down the drain before it's actually gone off. Australian households throw out a significant amount of dairy every week -- much of it still drinkable -- because the date on the carton is confusing, or because the milk wasn't stored as well as it could have been.
In this article from National Appliance Repairs, you’ll find a straightforward look at what those dates mean, how long different types of milk actually last, and what storage conditions make a real difference.
Fresh Pasteurised Milk: The Standard Carton
The milk most Australians buy week to week -- full cream, reduced fat, skim -- is pasteurised fresh milk. The use-by date on the carton is a safety date under FSANZ labelling rules, not a quality marker. Worth knowing the difference: use-by means stop there for safety reasons. Best-before means the quality is dropping but it's not necessarily a problem to drink.
Kept sealed in the fridge at or below 4°C, fresh pasteurised milk typically stays good for 12-14 days from processing (Dairy Food Safety Victoria). The carton date reflects that window.
Once you open it, 3--5 days is your real limit -- whatever the carton says. Every time it's opened, bacteria from the air get in and start the souring process faster.
Long-Life (UHT) Milk
UHT milk -- also sold as long-life milk -- gets heated to 140°C for two seconds during processing. That kills virtually all bacteria and microorganisms, which is why it sits on the shelf for so long.
Unopened, it keeps for six to nine months at room temperature. Open it and it goes in the fridge, where it's good for seven days. Australian UHT cartons have a use-by date on them, and Dairy Australia says to stick to it -- if it’s in a sealed carton, has no smell, then it doesn't matter.

What the Dates on Australian Milk Packaging Mean
Australian food labelling standards require fresh milk to carry a use-by date. This is a hard safety cut-off date, not a quality estimate.
Use-by date -- The last date the product is considered safe to consume. After this date, the product should not be sold or consumed regardless of appearance or smell. For fresh pasteurised milk in Australia, this is a genuine food safety date, not just a conservative guess.
Best-before date -- Some shelf-stable milk products carry a best-before date instead. This means the product is still safe to consume after this date, but quality (flavour, texture, nutritional content) may have declined. Long-life UHT milk may use either a use-by or best-before marking depending on the manufacturer.
When in doubt about which type of date is on your milk, look for the words "use by" or "best before" -- Australian labelling standards require the type of date to be clearly stated.
Where You Store Milk in the Fridge Matters
The back of the fridge is consistently the coldest part of the appliance. The door is consistently the warmest -- and the most subject to temperature fluctuation, because it's exposed to room temperature every time the fridge opens.
Milk stored in the fridge door experiences a mini-warming event multiple times a day. Over the course of a week, this accumulates. Moving the milk from the door shelf to the middle or back shelf of the main compartment is a small change with a real effect on how long it stays fresh.
The target fridge temperature for fresh milk is at or below 4°C. A fridge running at 6°C will cause milk to sour noticeably faster -- this is one of the more common reasons households find their milk going off before the use-by date. An inexpensive appliance thermometer will tell you whether your fridge is running at the correct temperature.
How to Tell If Milk Has Gone Off
Fresh milk's spoilage signs are usually reliable, unlike some other foods where contamination is invisible:
Smell: Soured milk has a sharp, acidic, distinctive odour. Fresh milk has a clean, faintly sweet smell. If in doubt, open the carton and take a careful sniff before pouring.
Texture: Fresh milk is uniform and smooth. Spoiled milk develops clumps, curds, or visible separation of solids. Even after shaking, curdled milk won't return to a smooth consistency.
Taste: Soured milk has a sharp, unpleasant flavour. A tiny taste test on the tip of the tongue will confirm it immediately.
Appearance: Fresh milk is opaque white. Spoiled milk may appear slightly yellowed, or have visible lumps.
Importantly, milk that has soured due to normal bacterial activity is not the same as milk contaminated with dangerous pathogens. The bacteria that cause milk to sour are generally not the ones that cause serious food-borne illness -- soured milk tastes unpleasant but is unlikely to make you seriously unwell. This is different from foods like cooked chicken where contamination is dangerous but invisible.
That said, do not consume milk that has passed its use-by date, regardless of how it looks or smells.
Can You Freeze Milk?
Yes. Fresh milk can be frozen for up to three months without significant safety concerns, though the texture changes on thawing -- the fat and protein components can separate, leaving the milk with a slightly grainy or watery texture. This separation doesn't affect safety or nutritional value, but it can make frozen-then-thawed milk less pleasant to drink straight. It works well in cooking, hot drinks, and baking where the texture change isn't noticeable.
Freeze milk in the original sealed container (leaving a few centimetres of headspace if the carton is nearly full, as liquid expands when frozen), or in a sealed freezer-safe container. Thaw in the fridge overnight and shake or stir vigorously before use.
FAQ
Can I drink milk one day after the use-by date?
In Australia, the use-by date on fresh milk is a food safety date, not just a quality indicator. Dairy Australia and FSANZ advise against consuming milk after its use-by date, as there is a risk of harmful bacteria growing to unsafe levels even if the milk looks and smells fine. The conservative approach is to treat the use-by date as a hard limit.
Why does my milk always go off before the use-by date?
The most common reason is fridge temperature. A fridge running at 6°C or above will cause fresh milk to sour significantly faster than one running at 3--4°C. Check your fridge temperature with an appliance thermometer and adjust if needed. The second most common cause is door storage -- moving milk to the back of the main compartment extends its life compared to the door shelf.
Does UHT milk need to go in the fridge before opening?
No. Unopened UHT milk is shelf-stable and does not require refrigeration. Once opened, it should be transferred to the fridge and consumed within seven days -- at which point it behaves like fresh milk.
Can I use milk that smells slightly sour in cooking?
Slightly soured milk (before it has fully curdled) can be used in baking -- its acidity reacts with bicarbonate of soda the same way buttermilk does, and the heat of cooking kills the bacteria responsible for souring. However, it should still be within its use-by date, and visibly curdled milk should not be used in any application.
Is organic milk handled differently for storage?
No. Certified organic fresh milk sold in Australia goes through the same pasteurisation process as conventional milk and follows the same use-by date rules. Some organic brands use extended-shelf-life processing techniques (closer to UHT but at slightly lower temperatures), which can give their fresh milk a longer use-by date than standard fresh milk -- but once opened, storage time and conditions are the same.
Conclusion
Fresh pasteurised milk should be used by its use-by date and consumed within 3 to 5 days of opening. UHT milk is shelf-stable for 6 to 9 months unopened and 7 days after opening. In both cases, a fridge running at or below 4°C -- and ideally 3°C -- is the key to reaching those full storage times.
If your milk consistently goes off before the use-by date and your fridge is set to a cold dial position, it's worth measuring the actual temperature with an appliance thermometer.
