What is the problem if the microwave is not heating?

If your microwave oven doesn’t heat, you may have a problem with the magnetron. This component is part of the high voltage circuit and provides the microwaves that generate the heat.

How do I know if my microwave fuse is blown?

It’s easy to tell if a glass fuse is blown; it will show scorch marks, and the filament will be melted. To check a ceramic fuse, use an ohmmeter or continuity tester. With an ohmmeter or multimeter, you should see a reading close to zero ohms if the fuse is intact, or infinite if it’s blown.

How do you test a microwave Thermoprotector?

If the microwave overheats, the thermoprotector trips to cut off voltage to the microwave. To determine if the thermoprotector is at fault, use a multimeter to test it for continuity. If the thermoprotector does not have continuity, and it cannot be reset, replace it.
