Microwave is a popularly used kitchen appliance these days. Like any other home appliance a microwave fails and breaks in its lifetime. Here are the common problems with microwave and their possible solutions:
Microwave does not heat
Microwave not heating is one of the most common problems with microwave. Most popular reason behind this issue is magnetron failure. A magnetron uses high voltage to produce microwave frequency to cook food. If the microwave is turned on when it is empty, this cause the magnetron to burn out. A burned magnetron has to be replaced as it cannot be repaired. Other probable causes behind this problem are faulty diodes, capacitor burn, defective door switch and transformer failure.
Refer to “No oven mitts! Is your microwave not heating food?”

Our other recommended replacements:
Microwave plate does not spin
In a microwave there is a rotating motor below the plate which is responsible for the rotation of spinning plate. So the most probable cause behind this issue is a worn out or burned motor. Motor can be easily replaced. However, if the motor is not defective this indicates a fault in the main control board. If the control board is fine then check touch pad or control panel for the problem.

Microwave light-bulb does not turn on during operation
There is a small bulb inside your microwave located behind the grill, which lights when the microwave runs. If the bulb does not work then it may have fused. Another possible reasons are faulty bulb socket and bad wiring. If the bulb, socket and wiring are fine then check the main control board. The control board may have gone bad and fails to send voltage to bulb socket.

What does the Waveguide Cover look like?
It was interesting to read that the control panel could also lead to the plate not turning. My grandmother noticed her plates were coming out hot from one side. It seems that the plate might not be rotating, so I’ll be sure to hire a technician to check it out.
Thanks for outlining these six common problems of microwaves.
We bought this microwave for my mother, this is the second oyster microwave we bought in less than a month that has had problems. We took that one back , bought another one and now this one the light bulb went out after the first week she used it! Im extremely unhappy. Oster used to be a good product, I’m not sure what is going on. This article tells me it can happen but not how to fix it. What can you do to help us? And what is going on with your quality control!?
Timer adds 24 seconds to any amount entered that is over 60 seconds. Under that number, it’s fine. Thanks for helping.

The main switch of my microwave remained on by mistake so it is not working now
My problem is up on top of microwave to right was a bad smell and smoke like it’s in the wires. Any idea?
We have a Panasonic Oven and Microwave, when my wife was baking a cake and after one hour she smelled burning and the not only was the cake burnt, but the internal glass window was crazed, Panasonic said it was miss use as we had must have scratched the glass and had not been cleaned it properly. Have contacted Trading Standards as it was Not fit for Purpose and in my professional opinion it was a malfunction of the electronics’ maybe the thermostat plus faulty manufactured hardened glass.
