Title:

Magnetron or Diode or both?

Text:

Hey folks, I have a GE Profile microwave and it started arcing.  I took it apart and pulled the magnatron.  It was arcing between the top of the magnatron tube and the shielding on the microwave.  I tested the diode and it is bad for sure.  My main question is did the magnatron possibly go bad and arc causing the diode to blow, or would the diode going bad cause the magnatron to arc.  I suppose my question boils down to do I just replace the diode or are both parts bad.  Oh and I tested the resistance on the Magnatron, the schematic calls for .5ohm and it measure .6-.7

Any help is appreciated.

Thanks,

Brett
