Is It Worth Repairing My Microwave?
The honest answer depends on age, repair cost, and what's broken. Get a virtual second opinion from a 35-year expert for $49.
Microwaves are unique in the repair-vs-replace conversation. They're the cheapest major appliance to buy ($100-500), which means the 50% rule kicks in fast. But many microwave repairs are also very cheap — $50-150. The math depends heavily on whether you have a countertop model (easy and cheap to replace) or an over-the-range or built-in unit (expensive to swap out). Let's break it down by type.
How long should a microwave last?
Average lifespan: 9 years (range: 7-12 years)
For countertop microwaves ($100-250), the 50% threshold is only $50-125. Most repairs approach or exceed this. For over-the-range models ($250-500), the threshold is $125-250 — more room for repairs to make sense. For built-in models ($400-1,000+), repair almost always wins.
Common microwave repairs and what they cost
Door switch
$50-120The door switch is the most commonly failed part. If the microwave won't start, this is usually why. Cheap part, but labor can be half the cost of a new countertop model.
Worth repairing? Yes for OTR/built-in, maybe for countertop
Turntable motor
$40-100If the turntable doesn't spin, the motor has failed. Simple and affordable on any type of microwave.
Worth repairing? Yes
Magnetron
$100-250The magnetron generates the microwaves. Replacing it on a $150 countertop model doesn't make sense, but on a $400+ over-the-range unit it's worth it.
Worth repairing? Only on OTR/built-in
High-voltage diode or capacitor
$50-150These power supply components fail occasionally. Cheap parts but require careful handling due to stored electrical charge.
Worth repairing? Yes for OTR/built-in
Control panel/touchpad
$100-250Buttons stop responding or display goes blank. On a cheap microwave, not worth it. On a $500+ built-in, definitely.
Worth repairing? Only on premium models
Fuse
$50-100A blown fuse prevents the microwave from turning on at all. The cheapest possible repair — but investigate why it blew.
Worth repairing? Yes
Almost always worth repairing
- Over-the-range microwave repairs under $200 — replacement includes $100-200 installation labor
- Built-in microwave repairs under $300 — cabinet refitting makes replacement expensive
- Fuse replacement ($50-100) on any type
- Turntable motor ($40-100) on any type
Probably not worth repairing
- Magnetron failure on a countertop microwave — buy a new one
- Control panel failure on a basic model — repair cost exceeds replacement
- Any repair over $100 on a countertop microwave under $200
- Repeated fuse blowing — indicates a deeper problem (often the magnetron or capacitor)
Countertop vs over-the-range: different math
For countertop microwaves under $200, repairs rarely make financial sense unless it's a fuse or turntable motor. Just buy a new one. But over-the-range (OTR) microwaves are different — replacement means paying for both the unit ($250-500) and installation ($100-200), so the effective replacement cost is $350-700. That makes $200+ repairs worthwhile.
Safety warning: microwave capacitors
Microwave capacitors store lethal voltage even when the unit is unplugged. This isn't a scare tactic — microwave capacitors have killed people. If any repair requires opening the microwave case, it should be done by someone who knows how to safely discharge the capacitor. We can diagnose the problem over video, but we'll always tell you when a repair is 'pro only.'

FAQ
My microwave sparks inside — is it dangerous?+
Sparking is usually caused by damaged waveguide cover (the cardboard-like panel inside) or arcing from food residue. The waveguide cover is a $5-15 part you can replace yourself. If the sparking comes from the magnetron area, stop using it and get it diagnosed.
Should I repair a $150 countertop microwave?+
Probably not — unless it's a $50 fuse or turntable motor. Any repair over $75 on a $150 microwave means you're better off buying new. The exception: if you love that specific model and it's discontinued.
My over-the-range microwave is only 3 years old — repair or replace?+
Repair. At 3 years old with 7-12 years of expected life, almost any repair makes sense. And remember — OTR replacement includes installation labor ($100-200) on top of the unit cost.
Can you diagnose a microwave safely over video?+
Yes. We diagnose based on symptoms: not heating (magnetron, diode, or fuse), sparking (waveguide or magnetron), not turning on (fuse, door switch, or control board). We never ask you to open the case or touch internal components over video.
