I too am facing the same problem; my microwave stopped heating the food, water, etc. Does anyone know how to actually diagnose if it is actually a magnetron tube problem, please advise.

Thanks, icansurf. I could find information on the microwave works but none on how to tell if the magnetron is faulty just looking at the outset. My microwave does not buzz and sounds just like it used to even now except no heating! So I can't be sure if its the HV Diode.
Oh hey icansurf,
Thanks a lot. I think I wasn't reading properly. On applicanceguru.com it is mentioned that it can be due to a circuit board or any high voltage component or a switch failure. Let's see; the technician would be here tomorrow from GE to see it. I will keep u posted on how it went.
Micro doesn't heat. All other controls appear to work. Is there a quick way to isolate the magnetron? Is the fuse only for the magnetron?
Microwave stopped during heating. Then microwave won t start. Light, timer nothing is on. The microwave is fixed in the furniture. Please advise
My microwave does not heat anything. Not sure if it is a magnetron or something different. Cannot open or find the service manual.
