The part(s) or condition(s) listed below for the symptom Refrigerator ice dispenser not working are ordered from most likely to least likely to occur. Check or test each item, starting with the items at the top of the page.
The dispenser control board governs most of the functions of the dispenser system. If the control board is faulty, it may stop supplying power to the entire dispenser system. If only one dispenser part is not working, test each of the dispenser components before testing the control board. It is more likely that a single part has failed. If the entire dispenser system is not working, the control board is more likely to be at fault.
The auger motor spins the auger blade and pushes the ice through the dispenser chute. If the auger motor is burned out or defective, the ice won’t move forward and fall through the chute. To determine if the auger motor is defective, pull out the ice bucket and turn the bucket auger by hand. If the auger turns freely, use a multimeter to test the auger motor for continuity. If the auger motor does not have continuity, or if the motor is getting power but won’t run, replace the auger motor.
When the dispenser lever is pressed, the auger motor rotates the auger. As the auger rotates, it pushes the ice toward the dispenser door and down the chute. If the auger is defective, it won’t be able to push the ice out of the dispenser. Check the auger to determine if it is broken or if it is disconnected from the auger motor. If the auger is broken, replace it.
