Here is a picture of everything installed: http://imgur.com/QsAMukc
I replaced the magnetron, diode, and capacitor. Microwave still buzzes loudly and does not heat. Any ideas? Is my wiring correct?
model is FGMV174KFB
had a similar issue. i hummed loudly for a bit but would cook…very slowly.
New mag didnt do it, but looks like replacing the high voltage transformer fixed it. Sounds like that is the only significant part you havent replaced yet.
You can chat with them, they seem to have a clue. They havent replied to these forum messages in a while
They told me part AP2148473 Fuse, Thermal Cutout was the reason for Hum and no heat. $50 but I will only buy a new one as my wife won’t use it repaired.
