Can anyone confirm whether following microwave oven components are
dead
-diode hvr1x8019:tested with analog ohm meter-short both directions
-rectifier 2x062h 8025:..open in both directions
tnx
The diode that reads short in both directions is definitely bad. The other, if
it's a high voltage rectifier, might have too high Vf to be properly tested by a
multimeter. Those are best tested by a Huntron Tracker or by replacement.
Or test them by applying mains voltage through one to a low wattage
incandescent bulb. If the diode is working, the bulb will be dim and
flicker slightly running on half wave power.
