High Voltage Diode Blown But Nothing Else Is Bad

crwdns2893800:0crwdne2893800:0:

My microwave was no longer heating. I took it apart and found the high voltage diode was bad but nothing else looked bad. I replaced the diode and it still didn’t heat yet the high voltage diode was not blown again. [br]
I’ve since checked all associated components and none look bad: HV capacitor, magnetron, HV diode, fuse.
What could have blown the diode, not looked bad yet not not blow it a second time when it still didn’t heat?

+Must my new magnetron look like this one?
