the way.
WARNING

Electric Shock Hazard.
Problem: Dispenser does not dispense ice
Problem Possible Cause To Correct
There is no power to the
dispenser. Is the dispenser plugged in?
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. Plug the dispenser in.
If no power is present, check the
cord and plug of the dispenser,
Replace cord set if wire is broken.
There is power to the
dispenser, however nothing
runs. 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. 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 does not test correctly,
replace the gearmotor.
