5-8 VENT EXHAUST BLOWER MOTOR
THIS COMPONENT REQUIRE REMOVAL OF
MICROWAVE OVEN FROM INSTALLATION FOR
SERVICING.
The blower is a two speed (HI-LO) capacitor run
blower assembly located on top of the micro-
wave oven. The blower is operated by low
voltage relays located on the smart board.
The blower motor has 3 winding which can be
tested for continuity from the front by removing
the top grille and opening the control panel.
RUN CAPACITOR
The run capacitor is located behind the top
grille 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 grille, 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 grille.
2. Open control panel and discharfe capacitor.
3. Disconnent two wires to run capacitor.
Continuity test across the two wires should ve
approximately 75 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 5 screws securing damper and motor
assembly 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.
