Everything works except heat

A common symptom of a failed magnetron is a failure to heat with everything else (magnetron fan, stirrer, timer, etc.) working fine. Check the GE manufacture date for the unit on its nameplate to determine the age of the magnetron. For GE models of the past, magnetrons had a 10 year parts replacement warranty. Magnetrons can be expensive, so you need to weigh all your options, i.e., repair versus replacement, before you commit to one solution.

There three area's of concern, magnetron, "heats food" the high voltage diode, "sometimes crack" the high voltage capacitor, "usually shorts"

remove the cover; you will see a large white ceramic cylinder fuse in clips, on top; replace it: radio shack sells the part.

magnetron problem DON'T KNOW IF WITH FIXING - WOULD LIKE TO KNOW MYSELF

Probably a burned out magnatron. Repair costs approach and sometimes exceed the cost of a new one! Get a new one.

Sounds like you've had a failure in the microwave portion of the unit.

Microwave not heating problems when the timer/controller board appears to function properly, are related to the following components -

1) Diode
2) Capacitor
3) Transformer
4) Magnetron
