Refer to page 3-10 for the procedure for servic-
ing the vent motor capacitor, page 3-8 for the
line fuse and oven thermostat, and page 3-6 for
the door switches.
1. Disconnect the electrical power to the
microwave oven.
2. Set the ohmmeter to the R x 1 scale.
3. To test the vent motor capacitor:
a) Disconnect the vent motor power con-
nector from the main harness connec-
tor.
b) Touch the ohmmeter leads to the main
harness connector with the yellow (pin
6) and white (pin 3) wires. The meter
should indicate several ohms and
gradually return to infinity.

5. To test the oven thermostat:
a) Disconnect the wires from the termi-
nals.
b) Touch the ohmmeter leads to the ter-
minals.
c) When the thermostat is open, (opens
@ 194˚F / 90˚C), the meter will indi-
cate infinity across the terminals.
d) When the thermostat is closed, the
meter will indicate continuity.
6. To test the door switches:
a) Disconnect the wires from the termi-
nals.
b) Touch the ohmmeter leads to the ter-
minals of the primary or secondary
interlock switches (normally-open). The
meter should indicate an open circuit
(infinite).
c) Touch the ohmmeter leads to the ter-
minals of the monitor switch (normally-
closed). The meter should indicate a
closed circuit (0
Ω
).
NOTE: Pressing the actuator button should
result in opposite readings (normally-open
should read closed, and normally-closed
should read open).
4. To test the 20A line fuse , touch the
ohmmeter leads to the ends of the fuse.
The meter should indicate continuity.
ELECTRICAL SHOCK HAZARD
Disconnect power before servicing.
Replace all panels before operating.
Failure to do so could result in death or
electrical shock.
