Primary
terminals
Secondary
terminal
Filament
winding
High voltage
transformer
Disconnect wires from terminals.
Measure for continuity of following
terminals:
Ohmmeter set on R x 1 scale
Primary winding................................
Secondary terminal to ground...........
Filament winding...............................
Ohmmeter set on R x 1000 scale
Primary winding to ground................
Filament winding to ground...............
Approximately 0.3 − 0.6 Ω
Approximately 70 − 100 Ω
Less than 1 Ω
Infinite

Magnetron
Disconnect wires from terminals.
Measure for continuity of following
terminals:
Ohmmeter set on R x 1 scale
Filament winding...............................
Ohmmeter set on R x 1000 scale
Filament winding to ground...............
NOTE: When testing magnetron verify
magnetron gasket is positioned correctly
and verify gasket is in good condition.
Less than 1 Ω
Infinite
Perform Microwave Power Test.
High voltage
capacitor
Discharge capacitor
Remove wires from capacitor terminals
and connect ohmmeter, set on highest
resistance scale to terminals.
Also check between each terminal and
capacitor case.
Between Terminals: Meter should
momentarily deflect towards zero then
return to over 5 MΩ. If no deflection
occurs, or if continuous deflection
occurs, replace capacitor.
Terminal to Case: Infinite resistance
High voltage diode
Discharge capacitor
Remove diode lead from capacitor and
connect ohmmeter.
Reverse leads for second test.
Infinite resistance should be measured in
one direction and 50KΩ or more in the
opposite direction.
NOTE: Ohmmeter must contain a battery
of 6 volts minimum.
Heating element
Disconnect wires from terminals.
Measure resistance across heating
element.
Terminal to terminal..........................
Approximately 9.6 Ω @ 68 − 86°F
Damper motor
Disconnect wires from terminals.
Measure for resistance:
Terminal to terminal..........................
Approximately 2930 Ω
Turntable motor
Disconnect wires from terminals.
Measure for resistance:
Terminal to terminal..........................
Approximately 3480 Ω
