Microwave repair cost guide
Over-the-range microwaves are the shortest-lived major appliance, so the repair-versus-replace line comes early. Here is what the six common failures cost — from the line fuse and door-interlock switch through the turntable motor, high-voltage capacitor, magnetron, and control board — and why every one of them is pro-only once the cabinet is open.

The repair-vs-replace rule for microwaves
With new over-the-range units starting around $200 and mid-range models around $350, most repairs above ~$150 do not pay off. Nothing here is a homeowner job either: the cheap parts sit behind the same high-voltage capacitor as the expensive ones, so every quote carries a service call. Repair only a newer microwave with a genuinely cheap fault — otherwise replace.

Frequently asked questions
How long should a microwave last?
A mid-range microwave typically lasts 8–10 yrs. Budget models run shorter and premium units longer — see the lifespan table above for the full tier breakdown drawn from NAHB and InterNACHI data.
Is it worth repairing a microwave?
It depends on age and the specific part. A typical major microwave repair runs about $120–$300 installed. If that is more than half the price of a comparable new unit and the appliance is past two-thirds of its expected life, replacement usually wins.
What microwave repairs can I do myself?
None of them. Every failure in the table above sits behind a high-voltage capacitor that can hold a lethal charge long after the unit is unplugged, so no microwave repair on this page is homeowner-serviceable — not even the turntable / fan motor, the cheapest row above, where the part costs a few dollars but reaching it does not. Budget for a licensed technician on any of this work, and weigh that service call against the price of a new unit.
Does my location change the repair cost?
Yes. Labor is the largest share of most repair bills, and technician wages vary by metro. The same job can differ 25% or more between markets — check your local rate on the labor-cost pages, then run the calculator with your actual quote.
