DRIVE MOTOR, THERMAL
OVERLOAD, & CENTRIFUGAL
SWITCH
Refer to page 4-21 for the procedure for ac-
cessing the drive motor.
1. Unplug dryer or disconnect power.
2. Turn off gas supply to dryer.
3. Disconnect the two blue wires from the belt
switch terminals and tape the wire ends to
-
gether so the bare ends are making con
-
tact.
4. Disconnect the drive motor wire connector.
5. Set the ohmmeter to the R x 1 scale.
6. Drive Motor Start Winding: Touch the
ohmmeter test leads to motor plug pins 3
and 4 (top right photo). The meter should
indicate between 1.4 and 2.8 Ω.
7. Drive Motor Main Winding: Touch the
ohmmeter test leads to motor plug pins 4
and 5. The meter should indicate between
1.4 and 2.6 Ω.
8. Thermal Overload: Touch the ohmmeter
test leads to the thermal overload termi
-
nals. The meter should indicate a closed
circuit (0
Ω).
9.
Centrifugal Switch:
a) Touch the ohmmeter test leads to
motor plug pins 6 and 5. The meter
should indicate an open circuit (infi
-
nite).
b) Touch the ohmmeter test leads to
motor plug pins 1 and 2. The meter
should indicate an open circuit (infi
-
nite).
c) Push and hold the centrifugal switch
actuator to activate the switch con
-
tacts (see bottom photos). Perform
steps 9a and 9b again. The readings
should each be reversed.

Electrical Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
