something got hot enough to melt the top side of the plastic shroud around the magnetron fan.  The heat  changed the plastic fan shroud's shape so fan can not turn.  I have cut that away and fan can turn now.  The unit buzzes when the door is shut and there is current flow to magnetron and capacitor from transformer.

Likely the high voltage  relay on the control board.

Thanks for the diagnosis, would this also cause a buzzing that seems much louder than normal operation?  by the way, I did check the door switches before I read this and they are all good.

Thanks,

I stand corrected, this is the correct board per Marcone as well...
