10.3 Magnetron
Continuity checks can only indicate an open filament or a shorted magnetron. To diagnose an open filament or
shorted magnetron.
1. Isolate the magnetron from the circuit by disconnecting the HV leads
2. A continuity check across the magnetron filament terminals should indicate one ohm or less
3. A continuity check between each filament terminal and the magnetron case should read open.
