SOURCE: Microwave doesn't heat anything

Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.

The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.

There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

Hello & Welcome to FixYa

F3H error means a failure in moisture sensor however, if you leave it unplugged for 15 minutes it should work, if won't then the sensor or the control board needs replacement. Please get back to me if you have any other questions.

My GE Profile JVM3670SK02 microwave stopped heating. Can it be fixed?


Anything can be fixed, it all depends on how much it will cost to repair. Sometimes it just pays to buy another microwave oven they have come down in price quite a bit

Good luck

Everything appears to work fine but it is not heating anymore.


If the microwave oven appears to be working but it is not heating the food, it is very possible that the magnetron, or its power supply has failed.

Microwave appears to work fine but will not heat at all.


Sounds like the thermal protector on the mag tube quit. It may have gotten too hot and opened up. That is the lesser of all the evils that can happen to a Microwave.
