Common Microwave Problems

February 3, 2021 Published by Leave your thoughts

Microwaves are one of the kitchen appliances people use most often. They’re convenient for everything from reheating leftovers for lunch to melting chocolate for dessert recipes. If you have microwave problems, it can ruin your plans, your lunch and your day. If you are in need of appliance repair in St. Peters, MO, you’re in luck. Here are some of the microwave problems that Crews Appliance Repair can help you address.

Microwave starts then stops

If your microwave starts but then stops before it runs through the timer, there are several things that could be wrong with your appliance. Possible reasons a microwave might start and then stop are a faulty door switch, a failed transformer, a defective touch pad or a faulty fan motor. Some of these issues are easier to repair than others, but none of them will stump an experienced professional.

Microwave stops heating up

Nothing is more frustrating than popping something in the microwave for a quick meal, hearing the timer ding and realizing that the microwave isn’t heating up at all. Usually, if this microwave problem happens to you, the problem is a magnetron failure. Microwaves cook your food through magnetrons, which use high voltage to produce microwave frequencies. You can damage the magnetron in your microwave by turning it on without anything in it. This will cause the magnetron to burn out.

Unfortunately, a burnt-out magnetron cannot be repaired, so you will have to have it replaced by a professional. If you find your magnetron is doing fine but your microwave still isn’t heating up properly, you might be facing faulty diodes, capacitor burn, a defective door switch or even transformer failure.

Sparking inside microwave

If this happens to you, be sure to immediately turn off your microwave and inspect it to see if the problem is clear. If you haven’t accidentally used your microwave with metal inside it, the problem could be a damaged rack support or paint wear on the microwave walls. You could also have a damaged wave guide cover or burned diode. Be sure to consult a professional if you have this problem.

Plate stops spinning

Microwaves have a rotating motor which spins the plate, making sure food heats evenly. If your microwave plate stops spinning, it’s reasonable to assume there’s something wrong with your rotating motor. These motors can just wear out after years of use, and it’s best if that’s the thing that’s causing your problem, because they are easy to replace. However, if your motor looks good, you could have bigger problems on your hands. The main control board, control panel or even touch pad could possibly cause this issue as well.

Microwave light bulb stops working

If the bulb located behind your microwave’s grill stops lighting up when the microwave is on, it could have fused. You could also have a faulty bulb socket or bad wiring, or even a control board issue.
