Microwave Repair Questions, Answered
Why is my microwave running but not heating?
A failed magnetron, a bad high-voltage diode or capacitor, or a faulty fuse are common causes. These parts hold a strong charge, so do not open the case. Call us and we will test them safely.
Why is my microwave sparking?
Metal inside, a damaged waveguide cover, or burnt food buildup can cause sparks. Stop using it, unplug it, and call us. Do not run it again until it is checked.
Why is my microwave turntable not spinning?
A loose or cracked roller ring, a worn coupler, or a failed turntable motor can stop the plate. Check that the ring and plate sit correctly. If it still will not spin, we can replace the part.
Is it safe to fix a microwave myself?
No. Even when unplugged, a microwave can hold a strong charge inside. Leave the case closed and call a technician.
How much does microwave repair cost in Sammamish?
The price depends on the part and the labor. We find the problem first, then give you the full price before any work starts. You choose whether to go ahead.
Is it worth repairing a microwave?
Sometimes. A basic countertop microwave is often cheaper to replace. Built-in, drawer, and over-the-range models are usually worth repairing. Your technician will give you honest advice. See our repair vs. replace guide for more.
Do you repair over-the-range and built-in microwaves?
Yes. We repair countertop, built-in, over-the-range, and drawer microwaves, including luxury models. See the brands we repair.
Can I get same-day or emergency microwave repair near me?
We do our best to offer same-day visits, depending on our schedule and the parts needed. You can send a request 24 hours a day on our contact page, or call now for emergency help.
Is it dangerous to keep using a sparking microwave?
Stop using it right away. Sparking usually means a damaged interior panel, loose wiring, or metal contact inside, and continuing to run it is a fire risk. Unplug it and call us.
Is it safe to run a microwave with a damaged door seal?
No. A damaged door seal can let microwave energy leak, so stop using it and call us to check the door switches and seal before you run it again.
Can a microwave be repaired if the keypad buttons don't respond?
Usually, yes. A dead keypad is often the control board or the membrane under the buttons, which we can test separately from the heating components.
Do you offer a warranty on microwave repairs?
Warranty terms depend on the repair and the parts used. We explain what is covered before you approve any work.
Can a microwave door that will not latch be repaired?
Yes, usually a latch or door switch replacement. Microwaves are designed not to run with the door open as a safety feature, so this needs fixing before the microwave will heat.
Do you repair microwave and range hood combo units?
Yes. Over-the-range microwaves that also vent as a range hood are repaired for both functions.
How long does a typical microwave repair take?
Most microwave repairs are finished in one visit. If a part like a magnetron has to be ordered, we tell you the wait time and book a return visit.
