Microwave Repair
Chicago - not heating or sparking?
Built-in and over-the-range microwaves are worth repairing because replacing one means matching a cabinet cutout. We service the units that are part of your kitchen, not the countertop ones.

Countertop microwaves are usually cheaper to replace than repair, and we will tell you that on the phone. Built-in, over-the-range and microwave-oven combination units are a completely different calculation, because replacement means matching a cabinet opening and a trim kit.
The most common fault by far is a unit that runs, lights up and turns the plate but produces no heat. That points at the magnetron, the high-voltage diode or the capacitor - and which one it is determines whether the repair is worth doing.
Microwave repair also involves stored high voltage that remains dangerous after the unit is unplugged. This is genuinely not a DIY appliance, and our technicians are trained and equipped for it.
Symptoms
Microwave Repair - faults we fix every week
If your appliance is doing any of the following, it is a repair we handle routinely and usually finish in one visit.
- Runs and lights up but food stays cold
- Sparking or arcing inside the cavity
- Loud buzzing or humming during operation
- Turntable will not rotate
- Door will not latch or unit stops when closed
- Touchpad unresponsive or keys stuck
- Over-the-range vent fan dead
- Interior light out or flickering
What actually fails
Magnetron. The component that actually generates heat. When it fails the unit still runs normally in every other respect, which is why customers assume the machine is fine and the food is at fault.
High-voltage diode and capacitor. These fail with the same no-heat symptom as a magnetron but cost far less to replace, so testing them first can be the difference between a $200 repair and a $450 one.
Door interlock switches. Three switches confirm the door is closed. When one fails the microwave refuses to run at all - a safety design working exactly as intended.
Waveguide cover. Arcing inside the cavity is usually a burnt waveguide cover, not a dying magnetron. It is a small part and a fast fix, but running the unit that way will damage the magnetron.
Touchpad and control board. Dead or intermittent keys come from a failed membrane touchpad. On built-in units this is a routine replacement.

Questions
Microwave Repair FAQ
My microwave runs but does not heat. What failed?
The magnetron, the high-voltage diode or the capacitor. We test the cheaper components first, because a diode repair costs roughly half of a magnetron job.
Is it worth repairing a microwave?
For a built-in or over-the-range unit, usually yes - replacement means matching a cabinet cutout and trim. For a countertop unit under $200, usually not, and we will say so.
There is sparking inside. Can I keep using it?
No. Stop using it. Arcing is normally a burnt waveguide cover, which is cheap to replace, but continuing to run it will destroy the magnetron.
Can I fix a microwave myself?
We strongly advise against it. The capacitor holds a dangerous charge even after the unit is unplugged.
Do you repair microwave-oven combination units?
Yes. Combination wall units are built-in appliances where repair is almost always the economical choice.
