WARNING
To avoid risk of electrical shock, personal injury, or death, disconnect power to oven and discharge capacitor
before servicing, unless testing requires power.
Illustration Component Testing Results
Open at 104° C (219° F).
Open at 138° C (280° F) and
closed at 82° C (180° F).
Infinite resistance should be
measured in one direction and 50KΩ
or more in the opposite direction.
NOTE: Analog meter must contain a
battery of 6 volts minimum.
Caution - Do not operate oven
when wire to terminal MT2 is
removed.
Infinite.
Approximately 40 Ω or more.

Infinite.
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.
Infinite.
Between Terminals: Less than 1 Ω.
Each terminal to ground measures
Infinite resistance.
NOTE: This test is not conclusive. If
oven does not heat and all other
components test good, replace the
magnetron and retest.
