You cannot test the HV diode with your meter. Your DVM would never have
enough break-over voltage to get the junction to properly conduct.
It is best to use a proper HV diode tester to check this type of diode. The
safest testing if you do not have the proper test gear, such as the HV
probe, microwave radiation checker, and etc, is to use parts substitution.
It is possible that any one or combination of parts can cause the microwave
to not function properly.

The high voltage diode tests open in both directions with my meter. I've never tested one of these puppies before. Can I assume it tests just like an ordinary diode? >From the sound I'd say the hi voltage transformer is working. Windings check out ok with meter as well as the filament in the tube seems ok. Getting about 85 ohms from the filament connections to the metal case of the tube. That's another one I'm clueless about, don't know if that's good or bad? Thanks in advance for any advice. I've got some regular electronics experience but never fooled around with a microwave before.
