Using a volt meter, measure the voltage (110-120 volts) between Wire #23 and ground, and Wire #22 and ground. If voltage
is present, or if only one wire (#22) has voltage, the centrifugal switch in the motor is bad. The entire motor must be replaced
(see Fig. 65).
NOTE: If line voltage is not present on either of the wires, recheck door switch, power switch and thermostat operation.
