THIS COMPONENT REQUIRES
REMOVAL OF MICROWAVE
OVEN FROM INSTALLATION FOR
SERVICING.
RUN CAPACITOR
The run capacitor is located behind the top grill
above the control area. The capacitor is used
for more torque and electrical phasing. Without
the capacitor the blower might run but would be
much slower.
TO TEST THE CAPACITOR
1. Remove grill, discharge capacitor and
disconnect one capacitor lead.
2. Make appropriate capacitor check (with analog
meter needle should rise then fall, cap is
charging then discharging).
TO TEST BLOWER WINDINGS:
1. Disconnect power and remove grill.
2. Open control panel and discharge capacitor.
3. Disconnent two wires to run capacitor.
Continuity test across the two wires should be
approximately 50 ohms of resistance. This test
allows you to read across all three windings at
the same time.
TO REMOVE VENT BLOWER
1. Remove unit from its installation.
2. Remove 3 screws securing motor to top and
back of unit and lift off. (1 screw is located
under damper.)
3. Disconnect blower plug.
NOTE: Place blower wires in routing slots to avoid
pinching of wires.
NOTE: It's normal that connector bracket bends
when reconnecting Hood Blower Motor
connector.
