This Amana over the range micro makes a humming/buzzing sound as the turntable rotates, but does not heat. Internet troubleshooting suggests that it might be a bad diode. Do you have a video that would describe diode replacement?
ANSWER Hello Lp. Sorry, there is no video at this time for diode replacement. It sounds like the diode and the magnetron will need to be replaced in the unit.
