When to Replace vs. Repair Your Appliance

Your dishwasher is making a grinding noise. Your oven takes 45 minutes to preheat. Your microwave sparks when you heat soup. The question every homeowner eventually faces: do I fix this thing or just buy a new one?

I install new appliances for a living, so you’d think I’d always say “replace it.” But that’s not honest, and this isn’t that kind of article. Sometimes a $150 repair buys you five more years. Sometimes a $300 repair delays the inevitable by six months. Here’s how to think about it.

The 50% Rule

This is the simplest framework, and it works most of the time:

If the repair costs more than 50% of a new replacement, replace it.

A dishwasher costs $500–800 new (installed). If the repair estimate is $300+, buy a new one. A wall oven costs $1,200–2,500 new. If the repair is $400, it’s probably worth fixing.

The math is straightforward, but there are factors the 50% rule doesn’t capture.

Average Appliance Lifespans

Here’s how long appliances typically last, based on what I see in the field:

Appliance	Average Lifespan	Signs It’s Dying
Dishwasher	9–12 years	Doesn’t clean well, leaks at door, motor noise
Microwave	7–10 years	Uneven heating, sparking, loud operation
Range Hood	10–15 years	Motor noise, weak suction, light failure
Electric Range	13–15 years	Inconsistent heating, element won’t cycle off
Gas Cooktop	15–17 years	Igniter clicks but won’t light, uneven flames
Wall Oven	14–16 years	Temperature way off, door seal damaged
Garbage Disposal	8–12 years	Frequent jams, leaks from bottom, slow grinding
Washer	10–13 years	Excessive vibration, won’t drain, mold smell
Dryer	10–13 years	Takes multiple cycles to dry, burns smell

If your appliance is within 2 years of these averages and needs a major repair, lean toward replacement.

When to Repair

It’s Young

A 3-year-old dishwasher with a failed pump is worth repairing. You’ve got 6–8 years of useful life left. The pump replacement might run $150–200, but you’d spend $700+ on a new dishwasher plus installation.

The Fix Is Simple

Some common repairs are cheap and easy:

• Dishwasher not draining: Clogged drain hose or bad drain pump ($80–150)
• Oven not heating: Failed heating element ($100–200)
• Microwave turntable not spinning: Motor replacement ($50–80)
• Disposal jammed: Reset button or foreign object (often free)

If the problem is isolated to one component and the rest of the appliance works well, repair usually makes sense.

It’s High-End

A Wolf or Sub-Zero range that needs a $500 repair is still a better value than a $5,000 replacement. Premium appliances are built to last and parts are available for decades. The calculus is different than with a $600 GE.

When to Replace

It’s Old and Needs a Major Repair

A 10-year-old dishwasher that needs a new motor, control board, AND has a leaking tub? That’s three problems on an appliance that’s already past its expected lifespan. Even if each repair is individually reasonable, stacking them up on an aging unit is throwing money away.

The Repair Would Cost More Than 50% of New

Self-explanatory. Do the math. Include installation in the “new” price — because you’ll need that installed too.

It’s a Safety Concern

Gas leaks, electrical faults, broken door latches on ovens — these aren’t “wait and see” situations. If an appliance has a safety issue and the repair is uncertain, replace it. Your family’s safety is worth more than the repair savings.

It Doesn’t Meet Your Needs Anymore

Sometimes the appliance works fine but doesn’t fit your life anymore. You remodeled the kitchen and need a different size. You switched from electric to gas. You need a larger capacity because your family grew. That’s not a repair decision — it’s an upgrade decision.

Energy Efficiency

Modern appliances are significantly more efficient than models from 10+ years ago. A new Energy Star dishwasher uses 3.5 gallons per cycle vs. 6+ gallons for older models. Over 5 years, the water and energy savings can offset a meaningful chunk of the replacement cost. This matters most for appliances you run frequently: dishwashers, washers, dryers.

The Gray Zone

Some situations genuinely could go either way:

A 7-year-old oven with a bad control board ($250 repair). The oven has maybe 7–8 years left. The repair is under 50% of replacement cost. But control boards are the most failure-prone component — if it fails again in 2 years, you’re out $500 in repairs on an aging appliance. I’d lean toward repair here, but it’s close.

A 5-year-old dishwasher with persistent leak. If the leak is from the door seal, that’s a cheap fix. If it’s from the tub (internal crack), that’s basically unrepairable. The diagnosis matters more than the age here.

A working appliance that’s ugly or outdated. This is a lifestyle decision, not a repair decision. If you’re remodeling and want matching stainless steel, just budget for new appliances as part of the remodel. Don’t feel guilty about replacing something that works.

What I Tell My Customers

When someone asks me whether to repair or replace, I give them the honest answer even when it means I don’t get an installation job. My reputation matters more than one install fee.

Here’s my quick decision framework:

1. How old is it? Past average lifespan → lean replace
2. What’s the repair cost? Over 50% of new → replace
3. Is it the first major repair? First one → probably repair. Second or third → replace
4. Is it a safety issue? Yes → replace immediately
5. Would you need to replace it within 2 years anyway? Yes → replace now and be done with it
