Over-the-range microwaves also work as the vent hood for the cooktop, so a fan or light problem matters as much as heating. Microwaves store high voltage even when unplugged, which is why internal repairs are not a DIY job.
Common problems
Microwave not heating
A microwave that runs but does not heat usually has a failed magnetron, diode or door switch.
Check first: Test with a cup of water for one minute.
When to call: Call if the water stays cold.
Microwave turntable not turning
The plate may be off its coupler, or the turntable motor may have failed.
Check first: Reseat the glass plate and roller ring.
When to call: Call if it still does not turn.
Microwave sparking
Sparks usually come from metal inside, a damaged waveguide cover, or burned spots on the cavity paint.
Check first: Stop using it and check for foil or metal trim on dishes.
When to call: Call before using it again.
Microwave making noise
Loud humming or grinding can come from the turntable motor, the fan, or the magnetron.
Check first: Note whether the noise happens with the vent fan off.
When to call: Call if it gets louder or stops heating.
Microwave door latch problem
A broken latch or door switch stops the microwave from starting, for safety.
Check first: Check whether the door closes with a firm click.
When to call: Call; door switches must be replaced correctly.
Over-the-range microwave vent fan problem
On over-the-range models, the vent fan pulls smoke and steam from the cooktop. A failed fan or switch leaves the kitchen smoky.
Check first: Clean the grease filters and test each fan speed.
When to call: Call if the fan will not run or will not shut off.
