A musty smell coming from the washing machine, or worse, laundry that smells off even straight out of a finished cycle, is one of the more common complaints we hear, and front-loaders in particular are prone to it. The good news is that in the vast majority of cases, it's not a mechanical fault at all. It's mould, mildew, or detergent build-up, and all three are genuinely fixable with a proper clean rather than a repair.
Here's what actually causes it and how to sort it out.
Why Front-Loaders Are More Prone to This Than Top-Loaders
Front-loading washing machines use a rubber door gasket to form a watertight seal during the wash cycle, and that gasket is also the single most common source of washing machine odour. Water, detergent residue, and lint get trapped in its folds, and because the door stays shut for most of the wash cycle, that moisture doesn't get the chance to evaporate the way it would in an open top-loader.
Front-loaders also tend to use less water per cycle by design, which is great for efficiency but means there's less water to rinse detergent residue away. Combine that with a door that's often left closed between washes, and you've got a genuinely ideal environment for mould and mildew to take hold.
The Usual Suspects
The door gasket
By far the most common cause. Pull back the rubber seal and check underneath it, since this is where hair, lint, coins, and general grime tend to collect out of sight.
Detergent and fabric softener build-up
Using more detergent than needed, or using a non-HE formula in a machine designed for high-efficiency detergent, leaves residue behind that doesn't fully rinse away. Over time it builds up in the drum, the dispensers, and the gasket, and it smells exactly as unpleasant as it sounds.
A closed, damp drum between washes
Leaving the door shut after a cycle traps moisture inside, which is precisely what mould needs to grow. This is one of the simplest habits to fix and one of the most effective.
A clogged pump filter
Lint, hair, and small debris build up in the pump filter over time, and standing water left behind after a cycle can develop a sour or musty smell of its own, separate from anything happening at the gasket.
How to Actually Get Rid of It
Start with the gasket. Pull it back fully and check for any visible debris, wiping it out with a rag dipped in warm soapy water or a vinegar solution. Use an old toothbrush to get into the grooves and corners, since that's usually where the worst of it hides. Rinse and dry the seal, then leave the door open so it can air out properly.
Next, run a hot cleaning cycle. Most front-loaders have a dedicated self-clean or tub-clean cycle, and it's worth using it with either a washing machine cleaner or two cups of white vinegar in an empty drum. If mould is visibly present rather than just a lingering smell, chlorine bleach poured directly into the detergent compartment (not the bleach compartment, and never mixed with other cleaners) run on the hottest cycle setting is the more thorough option. Follow up with a rinse and spin cycle afterward to clear any remaining residue.
While you're at it, pull out the detergent and fabric softener dispensers if they're removable and wash them separately with warm soapy water, since sticky residue builds up there just as readily as it does in the drum.
Finally, check the pump filter, usually accessed from a small panel at the front base of the machine on front-loaders. Clean out any trapped debris and lint, since a filter that's never been touched is a common, overlooked contributor to persistent smells.

Keeping It From Coming Back
Leave the door and detergent drawer open between washes so the machine can air dry properly
Wipe down the gasket after particularly heavy or muddy loads rather than waiting for your next scheduled clean
Use the correct amount of HE detergent for your machine, since more isn't better here, it just means more residue left behind
Run a hot cleaning cycle monthly, even if there's no smell yet, as routine maintenance rather than a reactive fix
Clean the pump filter every few months, more often in households doing frequent loads
When It's More Than a Cleaning Problem
If you've worked through all of the above and the smell keeps coming back, or if it smells more like sewage than mustiness, that can point to a drain hose installed incorrectly or a partial blockage further along the drain line rather than anything inside the drum itself. Our guide on water pooling under a washing machine covers a related issue worth ruling out if you're also noticing any dampness around the base of the machine.
National Appliance Repairs technicians work on washing machine repairs across all major brands, and can identify whether a persistent smell is a cleaning issue or something mechanical that needs attention. If your machine is also showing an error code rather than just smelling off, our guides on Samsung and LG error codes cover that separately, and if it won't turn on at all, see our guide on washing machines that won't turn on. Every repair comes with a 12-month parts warranty and 3-month labour warranty.
Frequently Asked Questions
Why does my front-loading washing machine smell worse than my old top-loader ever did?
Front-loaders use a sealed door gasket and less water per cycle, both of which make it easier for moisture and detergent residue to linger rather than evaporate or rinse away. It's a genuine design trade-off, not a fault with your specific machine.
Should I leave the washing machine door open between loads?
Yes. Leaving it open lets the drum air dry rather than sitting damp and sealed, which is one of the simplest and most effective habits for preventing mould and mildew from developing in the first place.
Can I use regular detergent in a front-loading washing machine?
It's not recommended. Regular detergent produces more suds than an HE machine is designed to rinse away efficiently, which leaves residue behind and contributes directly to odour build-up over time.
How often should I run a cleaning cycle on my washing machine?
Roughly once a month is a reasonable routine for most households, using either a dedicated washing machine cleaner or white vinegar. Increase the frequency if you're noticing smells more often than that.
When should I stop trying to fix the smell myself and call a technician?
If you've cleaned the gasket, run a hot cycle, and checked the pump filter and the smell persists, or if it smells like sewage rather than mustiness, it's worth having a technician check the drain hose and connections rather than continuing to guess.
The Bottom Line
Most washing machine odours come down to the door gasket, detergent build-up, or a closed damp drum between washes, and all three are fixable with a proper clean and a few small habit changes.

"How much is this going to cost me?" is usually the first question people ask when an appliance breaks down, and it's a fair one. The honest answer is that it depends on the fault, not just the appliance, which is why so few repairers publish a fixed price list. What follows is a realistic picture of what repairs actually cost across the market, drawing on how National Appliance Repairs and the broader industry typically structure pricing, and when repairing genuinely isn't the better option.
Why There's No Single Answer
A washing machine that needs a $40 drain pump is a very different job to one that needs a new control board, even though it's the same appliance and the same symptom from the outside: the machine's not working. Two callouts for the same appliance type can land at completely different prices depending on what's actually broken, whether the part is on the van or needs to be sourced, and how much labour the fix takes.
That's why most reputable repairers, National Appliance Repairs included, quote a service call fee upfront and then price labour and parts separately once the actual fault is diagnosed, rather than promising a flat rate before anyone's seen the appliance.
How the Pricing Structure Usually Works
Most callout-based appliance repair pricing in Australia follows a similar shape, even though the exact numbers vary between companies:
A service call fee covers the technician coming out and diagnosing the problem, generally including a set amount of labour, commonly the first 20 to 30 minutes. At National Appliance Repairs, our service call fee is $198 inc. GST, which covers up to 30 minutes of diagnosis or repair.
Beyond that included time, labour is billed incrementally, for us at $49 per additional 15 minutes. If the part needed is one our technicians carry on the van, which covers a wide range of common components, you'll get an instant quote and the repair usually happens on the spot. If it's a less common part that needs sourcing, you'll get a written quote before we order it, and there's no second call-out fee for the return visit.
What Repairs Typically Cost by Appliance Type
Costs vary meaningfully by fault, brand, and location, so treat these as general market ranges rather than a quote. They're based on typical repair costs reported across the Australian market.
Appliance
Typical Repair Cost Range
Common Faults Driving the Price
Dishwasher
$100 - $400
Drain pump, heating element, control board
Washing machine
$120 - $500
Drain pump, motor, drum bearings, control board
Dryer
$100 - $400
Heating element, thermal fuse, belt
Oven or cooktop
$50 - $600
Igniter, heating element, thermostat, control board
Fridge or freezer
$200 - $400
Compressor, thermostat, seal, gas recharge
Microwave
$75 - $300
Door switch, magnetron, control board
Rangehood
$80 - $250
Motor, capacitor, wiring
The wide range within each category comes down almost entirely to the specific fault. A thermal fuse or a door switch sits at the cheap end. A compressor, a motor, or a control board sits at the expensive end, since both the part and the labour to fit it are more involved. For a more specific picture, our washing machine, dishwasher, dryer, and fridge repair pages outline what each service typically involves.
What Actually Drives the Cost of a Repair
The fault itself: Electrical and electronic components, control boards especially, tend to cost more than mechanical parts like belts, hoses, or switches.
Part availability: A part carried on the van gets fitted the same visit with no return call-out fee. A part that needs to be specially ordered adds freight and, occasionally, a wait, though it shouldn't add a second service fee with a repairer that handles pricing properly.
Appliance age and brand: Older models and less common brands can have harder-to-source parts, which sometimes pushes cost and turnaround time up. Premium brands don't automatically cost more to repair, but their parts sometimes do.
Labour time: Some faults are a five-minute fix once diagnosed. Others involve dismantling part of the appliance to reach the faulty component, which adds labour time regardless of how cheap the part itself is.
When Repairing Isn't the Better Option
A commonly used guideline in the industry is the 50% rule: if the cost of the repair is more than half the cost of replacing the appliance with a new one, replacement is usually the better financial call. For premium or high-capacity appliances, that threshold can stretch closer to 70%, since the replacement cost is higher too.
Appliance age matters here as well. A fault on a machine that's two or three years old is almost always worth fixing. The same fault on an appliance well past ten years old is worth weighing against how many more issues might follow, particularly if it's had previous unrelated repairs.
A good technician will tell you honestly when a repair isn't worth it rather than just quoting the job. If replacement genuinely is the better option, National Appliance Repairs can supply, install, and remove the old unit as part of a seamless replacement, rather than leaving you to sort that out separately.
Frequently Asked Questions
Why don't appliance repairers just publish a fixed price list?
Because the same fault description can mean very different jobs depending on what's actually wrong once a technician looks at it. A fixed price list either overcharges for simple faults or undercharges for complex ones. A service call fee plus a diagnosis-based quote is the fairer structure for both sides.
What's included in a typical service call fee?
Usually the technician's visit and a set amount of diagnosis or repair time, commonly 20 to 30 minutes. At National Appliance Repairs, our $198 service call fee covers up to 30 minutes, with labour beyond that billed at $49 per 15 minutes.
Will I get a callout fee charged twice if a part needs to be ordered?
With a properly structured pricing model, no. The first visit's fee covers diagnosis, and a return visit to fit a sourced part shouldn't attract a second call-out charge, though it's worth confirming this with any repairer before booking.
Is it ever worth repairing an appliance more than once?
It depends what's failing. Unrelated faults on an otherwise healthy appliance are usually worth fixing each time. Repeated faults in the same system, or an appliance that's had several different issues in a short period, is a sign it may be nearing the end of its practical life.
How much does a typical appliance repair cost overall?
Across most appliance types, a full repair including the service call, labour, and parts typically lands somewhere between $150 and $450, though it can sit outside that range depending on the specific fault. Call 1300 434 380 for a free phone consultation and a more specific ballpark for your situation.
The Bottom Line
Appliance repair costs vary too much by fault to give one honest number, but the shape of the pricing is consistent: a service call fee covers diagnosis, and labour plus parts are quoted once the actual problem is known. If you're staring down a broken appliance and want a straight answer on cost before committing to anything, contact National Appliance Repairs or call 1300 434 380 for a free phone consultation, with same-day assessments often available, subject to availability, across Melbourne, Sydney, Brisbane, Adelaide, and Perth.
Booking a repair for the first time comes with a fair few unknowns. How long will it take? Will they actually have the part? What happens if it turns out to be a bigger job than expected? Not knowing what to expect is part of what makes a broken appliance feel more stressful than it needs to be.
Here's exactly what happens from the first call through to a finished repair with National Appliance Repairs, so there's nothing left to guess.
Step 1: The Call
You call, describe what's happening with the appliance, and the office team notes the details: the appliance type, the brand if you know it, and what it's actually doing (or not doing). At National Appliance Repairs, live calls are typically answered within about 30 seconds, and the team will confirm availability in your area and get a time booked in, often the same day in metro areas depending on technician availability. Office hours run Monday to Friday, 8:30am to 7pm, and Saturday, 8:30am to 4:30pm. You can browse our full range of services beforehand if you'd like to see what's covered for your specific appliance.
A rough description is fine at this stage. You don't need to diagnose the fault yourself, that's the technician's job once they're on site, but the more detail you can give (when it started, any noises, error codes, anything unusual) the better prepared the technician is before they arrive.
Step 2: The Technician Arrives and Diagnoses the Fault
On the day of the appointment, a technician arrives with a well-stocked van, and gets to work inspecting the appliance. This diagnosis is included in the service call fee, along with up to 30 minutes of labour if the fix is quick and the part's on hand.
Most repair technicians carry a wide range of high-turnover parts for the appliances they see most often, so a large share of common faults, drain pumps, thermal fuses, door seals, igniters, and similar, are diagnosed and available on the spot.
Step 3: You Get a Quote Before Anything Proceeds
This is where the two paths split, depending on whether the part needed is already on the van.
If the part's in stock, the technician explains the fault, the cost, and gets your approval before doing anything further. Nothing gets fitted without you knowing the price first.
If the part needs to be sourced, you'll get a full written quote rather than a guess. Once you approve it, the part gets ordered and a return visit is scheduled, with no additional call-out fee for that second visit. The diagnosis you already paid for at the first visit covers it.
Either way, you're never left wondering what something's going to cost after the fact. The quote comes before the work, not on the invoice at the end. Our pricing page goes into more detail on what typically drives the final number.
Step 4: The Repair Gets Done
For in-stock parts, this happens in the same visit as the diagnosis. For sourced parts, it happens at the scheduled return visit. Either way, the technician uses genuine or manufacturer-recommended parts and follows manufacturer-approved repair methods, which matters both for how the appliance performs afterward and for keeping any remaining manufacturer warranty intact where applicable.
Step 5: The Technician Walks You Through It
Once the repair's finished, the technician demonstrates that the appliance is working properly, answers any questions about what was actually wrong, and provides a detailed invoice along with the warranty details for the work completed.
Step 6: Your Warranty Kicks In
Every repair is backed by a 12-month warranty on parts and a 3-month warranty on labour. This covers the specific repair and the parts supplied, not the entire appliance, so it's worth understanding what the warranty applies to rather than assuming it covers unrelated future faults.
What Happens If Repair Isn't the Right Call
Occasionally a technician's honest assessment is that repairing isn't worth it, usually when the cost approaches or exceeds what a replacement would cost, or the appliance has a history of repeated unrelated faults.
When that's the case, National Appliance Repairs can supply, install, and remove the old unit, so replacement is handled as part of the same process rather than something you have to organise separately.

Frequently Asked Questions
Do I need to know what's wrong with my appliance before I call?
No. Describe the symptoms as best you can, and the technician will properly diagnose the fault when they arrive. A rough description is genuinely enough to get a booking made.
What happens if the technician doesn't have the part I need on the van?
You'll get a full written quote for the part and labour, and once you approve it, a return visit gets scheduled to fit it, with no extra call-out fee for that second visit.
Am I charged if I decide not to go ahead with the repair after the quote?
The service call fee covers the visit and diagnosis regardless of whether the repair proceeds, since that's the technician's time and expertise. No further charges apply if you choose not to proceed with the repair itself.
How long does a typical repair take from booking to completion?
If the part's on the van, it's often completed in the same visit as the diagnosis, sometimes same-day from the initial call. If a part needs sourcing, turnaround depends on part availability, though there's no unnecessary delay built into the process.
What does the warranty actually cover?
The 12-month parts warranty and 3-month labour warranty cover the specific repair and parts supplied, not the whole appliance or unrelated future faults. If the same issue recurs within the warranty period, that's covered.
The Bottom Line
Booking an appliance repair doesn't need to be a mystery. Call, describe the problem, get a technician out, get a clear quote before anything happens, and walk away with a working appliance and a warranty behind the work. Get in touch with National Appliance Repairs or call 1300 434 380 to book, with same-day appointments often available, subject to availability, across Melbourne, Sydney, Brisbane, Adelaide, and Perth.
A fridge that fails overnight, a fryer that won't heat during service, or an exhaust fan that trips a health inspection all have the same root cause more often than not: equipment that only gets attention once it's already broken. In a commercial kitchen, that's an expensive way to run things, since downtime during service hours costs far more than the maintenance that would have prevented it.
Here's a practical maintenance schedule from the team at National Appliance Repairs, covering the equipment zones that matter most, along with where Australian standards and food safety requirements come into play.
Why This Matters Beyond Just Avoiding Breakdowns
Equipment maintenance in a commercial kitchen isn't only about keeping things running. Exhaust and ventilation systems fall under fire safety requirements, grease build-up in ductwork is a recognised fire hazard, and inspectors checking food safety compliance look at equipment condition and cleanliness as part of a broader HACCP-aligned assessment, not just food handling on the day. A kitchen with documented, regular maintenance has an easier time at both fire safety and health inspections, since it can show a history rather than just a snapshot.
Daily Checks
Confirm exhaust fans are running before igniting any cooking equipment, and never operate cooking equipment without active ventilation
Wipe down and visually check grease filters for visible build-up, and empty drip trays
Check fridge and freezer temperatures at the start and end of service, logging both
Inspect dishwasher spray arms and filters for visible blockages before the first wash of the day
Check gas cooking equipment for any smell of gas before ignition
Weekly Checks
Remove and properly degrease baffle or mesh filters rather than just wiping the visible surface
Check make-up air grilles and supply louvers for blockages, since reduced make-up air causes negative pressure and can push smoke back into the kitchen
Inspect door seals on fridges, freezers, and ovens for gaps or damage
Test that all safety cut-offs and emergency stops on cooking equipment respond correctly
Clean condenser coils on refrigeration units where accessible, since dust and grease build-up here is one of the more common causes of sudden compressor failure
Monthly Checks
Full clean of exhaust hood interior surfaces, not just the filters
Check gas connections and fittings on cooktops, fryers, and combi ovens for any signs of wear or leakage
Inspect and clean dishwasher spray arm jets thoroughly, not just a rinse
Review temperature logs for any patterns suggesting a fridge or freezer is starting to underperform before it fails outright
Check door hinges and closers on walk-in coolers and freezers, since a door that doesn't seal properly drives up both energy costs and compressor strain
High-volume kitchens running dedicated commercial warewashers or glasswashers rather than a standard dishwasher should apply the same monthly spray jet and filter routine, since these units see far more cycles per day and clog proportionally faster.
Quarterly and Annual Requirements
Ducted exhaust systems in commercial kitchens typically fall under fire protection maintenance standards, commonly referenced against AS 1851 for scheduled servicing of fire protection systems including kitchen exhaust ductwork, alongside the ventilation design principles set out in AS 1668. Grease accumulation inside ductwork that isn't visible from the kitchen is one of the more serious commercial fire risks, and it needs a professional clean rather than an in-house wipe-down. Depending on your local council and insurer requirements, this is often required semi-annually or annually, with documentation kept on file.
Gas appliances should have a professional service and safety check at least annually, checking burner condition, gas pressure, and ignition systems, ideally timed before your busiest trading period rather than during it.

Building This Into Daily Operations
The checklist only works if it's actually followed, which usually comes down to how it's built into the shift rather than treated as an extra task. A few things that help:
Assign specific checks to specific roles rather than leaving them as a general team responsibility that no one owns
Keep temperature and cleaning logs somewhere they'll actually be filled in during service, not buried in an office
Schedule the less-frequent checks (weekly, monthly) on a set day rather than "whenever there's time," since that's how they get skipped
Treat unusual noises, smells, or slow-to-recover temperatures as early warning signs worth acting on, not something to note and revisit later
A fridge that fails during Friday dinner service costs far more than the maintenance that would have caught the early signs, both in lost stock and lost trade. Equipment that's regularly serviced also tends to fail more predictably, giving you time to plan a repair around quieter service periods rather than scrambling mid-shift.
Our commercial team offers extended hours and priority scheduling to minimise disruption to service.
Frequently Asked Questions
How often should commercial kitchen exhaust systems be professionally cleaned?
This generally sits at semi-annual to annual, depending on cooking volume, local council requirements, and insurer expectations. Kitchens with high-volume frying or grilling typically need more frequent cleaning than lighter-use café setups.
What's the difference between AS 1668 and AS 1851 for kitchen ventilation?
AS 1668 covers the design and mechanical ventilation requirements for commercial kitchens. AS 1851 covers the ongoing servicing and maintenance of fire protection systems, which typically includes kitchen exhaust ductwork given its fire risk from grease accumulation.
Do I need written maintenance records for health inspections?
Documented cleaning and temperature logs are a standard part of demonstrating HACCP-aligned food safety practices, and they make both routine and unannounced inspections considerably smoother. Check your specific requirements with your local council, since they vary by jurisdiction.
What's the most commonly overlooked piece of commercial kitchen maintenance?
Condenser coil cleaning on refrigeration units. It's out of sight, it's not part of daily service, and dust and grease build-up here is one of the most common causes of a fridge or freezer failing suddenly rather than gradually.
How much does commercial preventative maintenance typically cost?
It depends on your equipment count and service frequency. Call 1300 434 380 to discuss a maintenance plan tailored to your kitchen and get a clear cost breakdown.
The Bottom Line
Consistent, scheduled maintenance across cooking equipment, refrigeration, ventilation, and warewashing keeps a commercial kitchen running predictably and makes compliance far less stressful than treating it as a once-a-year scramble. If you'd like a maintenance plan built around your specific kitchen, contact National Appliance Repairs or call 1300 434 380 to discuss commercial servicing options across Melbourne, Sydney, Brisbane, Adelaide, and Perth.
The fan's running, the light's on, everything looks normal, and smoke is still hanging around the kitchen well after you've finished cooking. If you've already cleaned the filter and you're still getting this, the problem has moved past routine maintenance and into something mechanical: the fan, the motor, or the ductwork behind it.
Here's how National Appliance Repairs suggests working out which one, and what's realistic to fix yourself versus what needs a technician.
Rule Out the Filter First
If you haven't already, this is still the fastest thing to check. A saturated grease filter can cut airflow by a huge margin, and it's the single most common reason a rangehood stops clearing the air properly. Our guide on cleaning your rangehood filters covers that in detail. If the filter's already clean and the problem persists, keep reading.
The Paper Test
A simple way to check whether the motor's actually creating suction: turn the rangehood to its highest setting, and hold a piece of paper flat against the filter. If the motor's working, the paper should stick on its own. If it falls straight away, the motor either isn't generating suction at all, or something's blocking the airflow further along the system. This one test tells you almost immediately whether you're dealing with a motor problem or an airflow problem, which changes where you look next.
If the Motor Has No Suction at All
Start with power. Check the rangehood is properly plugged in, and check the circuit breaker hasn't tripped. Plug something else into the same outlet to confirm it's actually live.
If power's confirmed and the motor still isn't spinning, or it's spinning but weak, a failing capacitor is a common cause. The capacitor gives the motor the initial push it needs to start turning at speed, and when it degrades, the motor can hum without actually turning, or spin up slowly and never reach full power. This isn't something to test or replace yourself, since it involves live electrical components inside a sealed housing.
If the Motor Spins but Airflow Is Still Weak
This points away from the motor and toward the path the air has to travel. A few things to check:
Ductwork blockages or damage
Grease and debris build up inside ducting over years of use, the same way it builds up on a filter, just somewhere you can't see it. A flashlight down the duct opening, once the filter's out, will often show visible buildup or an obvious kink.
Duct length and bends
Every 90-degree bend in a duct run adds resistance, and a long run with several bends can genuinely overwhelm a motor that was never designed to push air that far. This is more of an installation issue than a fault, but it's worth knowing if you've recently renovated or the ducting was changed.
A blocked or stuck damper
Many ducted rangehoods have a damper flap at the exit point that's meant to open when the fan runs. If it's stuck shut, the fan is pushing air against a closed door, which both kills performance and puts unnecessary strain on the motor.
Make-up air
In a well-sealed kitchen, the rangehood needs somewhere for replacement air to come from. Without it, the fan can struggle against negative pressure in the room, which shows up as reduced performance even though nothing's actually broken.
Noise Is Often the Earliest Warning Sign
Rattling, buzzing, or grinding noises usually show up before a motor fails completely, and they're worth paying attention to rather than living with. Loose screws or a fan blade that's come slightly out of balance are common, low-cost causes. A grinding or screeching noise more often points to worn motor bearings, which will eventually lead to full motor failure if left alone.

What You Can Check Yourself
Run the paper test to confirm whether the motor is actually generating suction
Check the ductwork with a flashlight for visible blockages once the filter's removed
Check the damper flap opens freely when the fan runs
Tighten any visibly loose screws or panels if you're hearing rattling rather than grinding
Confirm the rangehood is on its own circuit or at least not sharing one with something that trips the breaker regularly
Why Motor and Fan Repairs Need a Professional
A rangehood sits directly above a heat source, and its motor and electrical components are the parts most likely to be affected by years of grease and heat exposure. Testing a capacitor, replacing a motor, or working inside the housing involves live electrical components in a location where getting it wrong has real consequences. This isn't a filter clean, and treating it like one is how minor electrical faults turn into bigger, more expensive problems.
National Appliance Repairs technicians handle rangehood repairs across all major brands, including motor replacements, capacitor faults, and wiring issues. Most jobs are diagnosed and fixed in a single visit, backed by a 12-month parts warranty and 3-month labour warranty.
Frequently Asked Questions
How do I know if it's the motor or the filter causing weak suction?
Clean the filter first, since it's the more common and easier cause to rule out. If the problem persists with a genuinely clean filter, run the paper test: hold paper against the filter at full fan speed. If it doesn't stick, the issue is with the motor or something blocking airflow further along.
Why does my rangehood make a humming noise but the fan doesn't spin?
This usually points to a failing capacitor, which is meant to give the motor the push it needs to start turning. A motor that hums without spinning, or spins weakly, needs a technician to confirm and replace the capacitor.
Can I clean the ductwork myself?
You can inspect it with a flashlight once the filter's removed, but a genuine deep clean of long duct runs usually needs professional equipment to do properly, especially on rangehoods that haven't been serviced in several years.
Why is my rangehood not clearing smoke even though the fan is running at full power?
This can mean the hood was undersized for the cooktop to begin with, or that duct resistance from a long or bent run is overwhelming the motor's capacity. Both are worth having assessed rather than assuming a simple fix will solve it.
How much does it cost to repair a rangehood motor?
It depends on the fault. A capacitor replacement is a smaller job than a full motor replacement. Call 1300 434 380 for a free phone consultation and ballpark pricing before booking.
The Bottom Line
A clean filter solves most rangehood complaints, but if that's already sorted and smoke or steam is still lingering, the fault has shifted to the motor, the ductwork, or the airflow path. The paper test takes ten seconds and tells you which direction to look. Still not clearing properly after that?
