Microwave Repair

Microwave repair and replacement.

Over-the-range microwaves are the most common call, they share a vent with the range and fail in specific patterns: door switches, magnetrons, turntable motors, and control boards. Countertop and built-in trim-kit units are covered too. Safety first: the tech discharges the high-voltage capacitor before any internal work.

What do homeowners ask about Microwave Repair?

Is it worth repairing a microwave or should I replace?

Cheap countertop units are rarely worth repairing, just replace. Over-the-range and built-in units cost several times as much to replace, so they are almost always worth repairing. Magnetron swaps on a built-in are a classic repair-wins case.

What's the #1 microwave failure you see?

Door switches (interlock switches). They're mechanical and wear out at about the 6-year mark. When they fail the microwave won't start at all, or it runs but doesn't heat. It's one of the quickest, most affordable microwave fixes.

Is microwave repair dangerous?

It can be, for someone without training. The high-voltage capacitor stores lethal charge even after unplugging. The tech discharges it safely on every call before touching internals. This isn't a DIY-safe repair beyond cleaning and bulb changes.

My over-the-range microwave vent isn't working. Can you fix that?

Yes. Usually it's the fan motor, the speed-control board, or a blocked duct. The tech tests all three and quotes in writing. An OTR service call is also the right time to have the charcoal filter and grease filter cleaned; ask the tech to include it in the quote.

Do you work on built-in microwaves with trim kits?

Yes. Built-in units usually require the trim kit to be removed for access, which the tech handles as part of the repair, including reassembly and realignment.
