Default Microwave - No Heat
Model Number: JVM1660WB005   Brand: GE   Age: 5 - 10 years   

Appliance Parts from AppliancePartPros.com


Everything works, just doesn't heat anything. I have 120 VAC on the primary side of the big transformer under the magnetron so I suspected I had a bad magnetron. I ordered a new one from AppliancePartsPros (order # 417722) and installed it, but no change.
I appreciate any help you can give.

Default Microwave - No Heat

Thanks for your help, but I am not familiar with any diode associated with the magnetron. Also, there is not a diode listed in the critical parts list for service that came with the microwave. Is it on the smart board or a stand alone part?
Thanks

It is connected to the high voltage capacitor.

You were right! The diode was shorted out. Thanks for the part number. While I'm ordering this part and have the microwave unit all apart, are there any other parts you would recommend I replace on a 7-year old unit?
Thanks again.

TRY REPLACING THE DIODE ON IT IT LOOKS LIKE A FUSE.
