Electric Shock Hazard.
Problem: Ice Does Not Dispense When Rocking Chute is Depressed.
Problem Possible Cause To Correct
There is power to the
dispenser, however nothing
runs. The dispenser is plugged in with
power to the receptacle. With a
meter, check to see if power is getting
to the white and black cord wires
inside the electric box.
Is power able to conduct through the
microswitch? With the dispenser
unplugged and the ohm meter probes
on the “C” and “NC” terminals,
depress the microswitch lever. The
mere reading should display ohms.
Release the microswitch lever. The
ohm value should register continuity.
If the gearmotor attempts to start but
fails to do so, check the capacitor.
Use a capacitor checker according to
the instructions supplied.
If gearmotor fails to attempt to start,
check the gearmotor. First,
disconnect power from the dispenser.
Then disconnect the gearmotor wires
in the junction box. Check for
continuity through the gearmotor. If no power is present, check the
cord and plug of the dispenser,
Replace cord set if wire is broken.
Check continuity at the microswitch,
replace the switch or repair the
connection if defective.
If the capacitor does not test
correctly, replace the capacitor.
If gearmotor tests open, replace the
gearmotor.
