Microwave Repair in Charlotte, NC

We repair over-the-range and built-in microwaves in homes across Charlotte, NC and nearby towns. These are the ones mounted under a cabinet or set into the wall, where a replacement means new mounting, venting and trim.

For a small countertop microwave, replacing it often makes more sense than a repair. If that is your case, we tell you before you spend money.

Common microwave problems we fix

These are the likely causes, not a diagnosis. We confirm the cause with tests before we replace any part.

Runs but doesn't heat

Likely cause: A failed magnetron, high-voltage diode, capacitor or high-voltage fuse.
What we do: We discharge the capacitor safely and test each part of the high-voltage circuit.

Completely dead

Likely cause: A blown main fuse, often caused by a failing door switch, or a tripped thermal cutoff.
What we do: We replace the fuse and find what blew it, so it does not blow again.

Sparking inside

Likely cause: Metal inside, food buildup, or a burned waveguide cover (the small panel on the side wall).
What we do: Stop using it. We replace the waveguide cover and check the inside walls for damage.

Turntable doesn't turn

Likely cause: The plate is off its coupler, the roller ring is dirty, or the turntable motor failed.
What we do: We reseat the plate and test or replace the motor.

Vent fan turns on by itself

Likely cause: Over-the-range models turn the fan on when they sense heat from the cooktop below. If it stays on when everything is cool, a sensor or relay may have failed.
What we do: We check the heat sensor and the control relays.

Buttons don't respond

Likely cause: The control lock is on, or the keypad or control board failed.
What we do: We check the lock and test the keypad and the board.

Door won't latch or close right

Likely cause: A broken latch hook or a worn door switch.
What we do: We replace the latch parts and test the door switches, which also stop the microwave when the door opens.

Microwave safety

Do not open the microwave's outer case. It holds a dangerous high-voltage charge in its capacitor even after it is unplugged.
If it sparks, stop it and do not use it again until it is checked.
If the door is bent, a hinge is broken, or the door seal is damaged, stop using it.
Never run it empty. Running a microwave with nothing inside can damage it.

Quick checks before you book

Check the breaker, and the outlet for plug-in models.
Look for a control lock. Many models lock when you hold Cancel or Start for a few seconds.
Make sure the turntable sits on its coupler.
Clean food splatter off the inside walls and the small panel on the side wall.

Microwave repair questions

Is it worth repairing my microwave?

For over-the-range and built-in microwaves, often yes, because replacing one means new mounting and sometimes new trim. For a basic countertop microwave, replacing it usually makes more sense. Call us and we will help you decide.

Why does my microwave run but not heat?

A part in the high-voltage circuit has failed: the magnetron, the diode, the capacitor or a high-voltage fuse. These parts are dangerous to test without training.

Can I keep using a microwave that sparks?

No. Stop using it. Sparking usually means a burned waveguide cover or metal inside, and it can damage the microwave further.

Why does the fan come on by itself?

Many over-the-range microwaves turn the vent fan on when they sense heat from the cooktop below. That is normal. If it stays on with the cooktop off and cool, something in the control has failed.

Do you repair microwave and wall oven combos?

Yes. We work on combination units and check both parts when one fails.
