Knowing When to Repair an Appliance and When It’s Time to Replace It

Is your 10-year-old washing machine making a terrible racket? Won’t the oven you’ve had ever since you bought the home heat evenly? Or your old dishwasher is leaving spots on everything?

Kitchen appliances tend to last a long time, but after a couple of years of working, they start showing problems. Most people will naturally wonder whether it’s even worth fixing or replacing it with a spanking-new model. With decades of experience fixing appliances, our technicians at National Appliance Repairs have heard this question a lot. What most people don’t know is that there’s actually a framework to help make this seemingly tough decision (that we use all the time!)

The 50% Rule -- And Why It Usually Works

If the repair cost is more than 50% of what a replacement would cost, replace it. Simple as that.

If your 10-year-old washing machine needs a new drum, for instance, that’s typically a $600 replacement job. A new washing machine from a reputable brand will run you about $1,200. That’s 50%, so it’s borderline. You could go either way depending on how long you’ve had the washing machine (and what feature the new model you’re eyeing have – if it’s got new bells and whistles like Wi-Fi control that seems more convenient to have, give it a shot!)

But if your fridge seal is cracked… we typically quote $150 for this. A new fridge will cost you $1,500 – so obviously, fix it.

Besides saving you money by stopping you from replacing a perfectly good appliance that just needs a quick, cheap fix, this rule also works because it accounts for the fact that if a major, expensive component is failing, others are probably close behind. 

Take our washing machine example: if you need a new drum for a washing machine that’s been serving for 10 years, you’ll likely need other repairs done soon. So rather than taking on the cost of the drum plus all those other future repairs, a new machine will serve you better.

How Old Is Too Old?

Appliance lifespan varies wildly:

• Washing machines: 8-12 years is typical. If yours is 7 years old and failing, repair it. If it's 13 years old, replacement might make sense even if the repair seems cheap. You'll be looking at more failures soon.
• Dishwashers: 7-10 years. These fail frequently in their final years. If it's under 7 and breaks, usually worth fixing.
• Fridges: 10-15 years. Older fridges often become very expensive to run. Even if a repair is cheap, the energy cost of an aging fridge might justify replacement.
• Ovens: 10-15 years for gas, 13-15 for electric. Ovens often outlast other appliances. If yours is still under 10 and something goes wrong, fix it.
• Cooktops: 10-15 years. Gas cooktops can last longer; electric ones less so.

These aren't hard rules. A well-maintained appliance might last longer, while a poorly used one might fail sooner, but you can use this list as a helpful reference sheet.

Asking the Right Questions

Question 1: What's the repair cost vs. replacement cost?

Get an actual quote before deciding. Don't guess. Call a technician and ask what the repair would cost. Check the price of a replacement model similar to yours (or better, if you're considering an upgrade). Then apply the 50% rule.

Question 2: How old is the appliance?

If it's close to the typical end-of-life age according to the sheet above and needs a major repair, lean toward replacement. If it's younger and just needs a component, lean toward repair.

Question 3: What's failing?

Some failures are death sentences. A compressor going bad in a fridge? Probably replace it. A seal on a door? Definitely repair it. The specific part matters tremendously.

Question 4: Is it a recurring problem?

Is this the first issue you've had, or the third visit from the repair technician in two years? Chronic problems that keep recurring signal a machine that's ready to go. One major issue on an otherwise reliable appliance? Fix it.

Question 5: What will you do with the replaced appliance?

If you're replacing with something significantly better (more energy-efficient, more features, better brand), the financial comparison changes. A $150 repair on an old fridge might make sense against a basic $600 replacement. But if you could get a better, more efficient model for $900, that's worth considering.

The Hidden Costs of Older Appliances

Energy usage is the killer nobody thinks about. An old refrigerator uses 30-50% more electricity than a modern model. Over a decade, that adds thousands to your power bill. In Perth and Adelaide, where air conditioning and heating strain the grid, an old fridge running constantly becomes genuinely expensive.

Likewise, an older washing machine might use 40% more water per load. An older dishwasher the same. These aren't huge differences per load, but they compound over years.

When you're deciding whether to repair an 12-year-old fridge or replace it, don't just compare the repair cost to the new fridge cost. Factor in that the old fridge will cost $300+ more per year to run.

Common Scenarios and the Smart Decision

Frequently Asked Questions (FAQs)

If my appliance is under warranty, should I always repair rather than replace?

Not necessarily. Warranty doesn't change the economics. If the repair is still more than 50% of replacement cost, the decision stays the same. However, check your warranty terms first. Some warranties only cover specific parts, leaving you responsible for labour costs.

What if the repair technician recommends replacement but I think repair is worth trying?

You have the right to try. Ask them to be specific about why they think replacement makes sense. Is it because the repair is risky and might fail again? Because parts are hard to source? Because the appliance is near typical end-of-life? Understanding their reasoning helps. If you still want to repair, get a written quote and understand the risks.

Are refurbished appliances a good middle-ground option?

Sometimes. A refurbished appliance from a reputable seller offers some risk reduction compared to used. But quality varies wildly. Check the warranty carefully. A refurbished appliance with only a 30-day warranty is risky. A 1-year warranty is better. Refurbished makes sense when you want an upgrade without buying brand new.

Should I factor in the hassle and inconvenience of being without an appliance?

Yes, this matters but often gets undervalued. A washing machine or dishwasher repair might take a week. That's genuinely inconvenient. But don't let inconvenience alone drive a bad financial decision. Instead, ask: can I live without it for that long? If waiting a week for a repair means renting a hotel or eating out constantly, replacement starts looking better. But if it's just a minor inconvenience, it shouldn't override the 50% rule.

I'm going to stay in my home for 20+ more years. Does that change the repair vs. replace calculation?

Somewhat. If you're staying long-term, longevity matters more. A 12-year-old appliance with one repair might fail again within 3 years, costing you another repair. Replacement with a new, reliable appliance protects you for the next decade-plus. This is where preventative replacement makes sense. However, the 50% rule still applies. Don't replace something just because it's old if the repair is cheap and it's otherwise reliable.
