Frequently asked questions
Why does my microwave run but not heat?
This is most often a failed magnetron or high-voltage diode. Because microwaves store high voltage, this should only be diagnosed by a trained technician.
Is it worth repairing a microwave?
For inexpensive countertop units, replacement is often cheaper. For built-in and over-the-range models, repair usually makes good sense — we will tell you honestly.
My microwave sparks inside — what should I do?
Stop using it and have it checked. Sparking is often a damaged waveguide cover or rack, which is a quick repair but should not be ignored.
Do you repair over-the-range microwaves?
Yes, including the vent fan and light functions on over-the-range models.
