As the motor starts running, the motor switch
moves opening the start winding and trans­
ferring the power from the normal speed
winding to the slow speed winding. The mo­
tor is running on the slow speed winding in
the direction indicated.
MOTOR CIRCUIT TESTING
The motor overload protector, motor starting
switch and the motor are the three compo­
nents that should be tested if the motor as­
sembly is suspected of being the cause of a
service problem. The power cord should be
unplugged and all wiring connections from
the machine wiring harness to the motor start­
ing switch should be disconnected before any
testing is done to the motor.
draw. The contacts reset automatically when
they cool off. If the contacts open, all power
to the motor is cut off.
If the overload protector opens repeatedly,
check the following:
1. A binding condition in the motor or in the
drive train.
2. Poor electrical connections causing a low
voltage situation.
3. The motor overheats because of a re­
stricted air flow. (The motor can get as
hot as 200 degrees Fahrenheit and still be
operating within design specifications.)
