I was heating my tea and I heard a loud pop and the unit turned off...I thought I had blown a fuse and went out and checked fuse box..flipped all fuses and microwave still not turning on at all...micorwave...


The description you provide indicates the magnetron has failed, "heats food" and blown the main fuse in the microwave oven, since the unit is 10 years old it is much cheaper to replace with a new one rather than have it repaired.

Microwave popped and now does not heat


Okay, first we need to separate the situations. You were boiling water on the stove and had the range hood fan running to **** up the steam. Then you put something in the microwave to heat and you heard a pop and then zip-o.

The water on the stove has nothing to do with the situation, the fan you turn on is not part of the microwave, so it has nothing to do with the microwave.

The pop you heard and then the humming suggests the magnetron failed. You said you found a blow fuse and replaced it and still nothing, right? The magnetron is the most likely culprit...I would think it is safe to say that the magnetron shorted and drew enough current to blow the fuse.

Replace the magnetron and if that doesn't work, let me know here. Good Luck!

Not heating anything, very loud


Sounds like the magnetron has failed. This is the component that produces the microwave that heats the food. The cost of the magnetron is about 95% of the cost of a microwave . 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.

Microwave on but does not heat


If it is less than 5 years old, it is probably worth it to fix it. Sounds like a magnetron. The part should be covered by GE
