Question about Microwave Ovens
Posted by Anonymous on
Check the door safety interlock safety switches for proper operation. You will find them inside the cabinet.
If they have failed, the oven thinks the door is open and therefore will not turn on the heat. This is the most common reason for failure.

It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.
