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.

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.

If the control board is fine then check touch pad or control panel for the problem.

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.

    I want to know who the genius is who thought that making all the buttons on a microwave dark colored like the background was a good idea. Not all of us has a spotlight on our microwaves to see the buttons clearly. They should all be in white against the dark background.
