I have a non-heating microwave oven that I just opened up. I tested the HV diode and it seems to be acting as a good diode. The capacitor measures 1.0
4 uF and >30 MEG-ohm, so it should also be good. That leaves the Magnetron. Is there a way to check the tube without powering it up with high voltage? Any visual signs might indicate it's bad?- posted
