Gene,

I have determined that the HV Diode is no good. It tests 'infinity' (open) in both bias directions (tested with a high quality Fluke Meter)
I would like to know; in your opinion; if I should order more parts than just the diode? I didn't get any spark whatsoever out of the HV Capacitor when I went to discharge it prior to removal of the diode for testing. I did not, however, test the capacitor, after I found the diode bad.

Thanks,
Al

My Amana ACO 1860 AW (over the range) microwave is not heating.
It seems everything else works fine.
I located the tip sheet inside under control cover.
Fuse tests OK.
Magnetron tests OK.
HV Transformer tests OK except for Filaments to chassis tests shorted....sheet says they should test infinite.
Does this tell me that the HV transformer is NG? <snip>
