Ice Dispensing Troubleshooting 

 

 

 

WARNING

 

Unplug unit before servicing or cleaning. 
 
Ice dispenser bin contains parts that can move at any 
time and will cause injury if hands are in  
the way. 

 

 

 

 

WARNING

 

Unplug unit before servicing or cleaning. 
 

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.
