MAGNETRON TESTING

WARNING!!

The microwave circuit cannot be worked
on with the unit on. The unit must be
disconnected from the power source.
Failure to do so could result in injury or
death.

WARNING!!

The HV Capacitor must be discharged
before proceeding.

Checking a Magnetron for Open or Shorted
Filaments:

1. Disconnect the AC power source and

discharge the High Voltage Capacitors.

2. Isolate the magnetron from the circuit by

removing the wires from the F and FA
terminals.

3. An ohmmeter connected between the filament

terminals (F, FA) should indicate a reading of
less than 1 Ohm.

4. A continuity check between either filament

terminal and the magnetron chassis should
indicate an infinite resistance (open).

MAGNETRON REMOVAL AND REPLACEMENT

1. Remove door hinge bar support angle.

2. Remove magnetron cooling fan, duct work and

magnetron as an assembly.

3. Unplug and remove magnetron.

4. Install new magnetron.

5. Check the oven for microwave leakage. Refer

to page 6-1 for instructions.
