5-1 High Voltage Transformer
1. Remove connectors from the transformer terminals
and check continuity.
2. Normal resistance readings should be as follows:
Secondary ..........................Approx. 123
Ω
Filament .............................Approx. 0
Ω
Primary...............................Approx. 2.30
Ω
(Room temperature = 20
˚C)
5-2 Magnetron
1. Continuity checks can only indicate an open filament or a
shorted magnetron. To diagnose an open filament or
shorted magnetron.
2. Isolate the magnetron from the circuit by disconnecting its
leads.
3. A continuity check across the magnetron filament
terminals should indicate one ohm or less.
4. A continuity check between each filament terminal and the
magnetron case should read "open".

PRECAUTION
1. High voltage is present at the high voltage terminal of the high voltage transformer during any cook cycle.
2. It is neither necessary nor advisable to attempt measurement of the high voltage.
3. Before touching any oven components, or wiring, always unplug the oven from its power source and discharge the high voltage
capacitor.
