Electrical Shock

Hazard.

Disconnect electrical power to the icemaker - dispenser before beginning.

1.Remove the electrical wires from the gear drive motor.

2.Unscrew the 4 cap screws holding the gearmotor to the gearmotor plate.

3.Remove the gearmotor from the icemaker.

To Inspect the gearmotor.

onto the lower case, cover will have to be moved closer to the second gear after the output gear has cleared the second gear top bearing.

E)After the case is together, and the locating pins are secure in both ends, replace all cap screws.

4.Bench test the gearmotor, check for oil leaks, noise, and amp draw.

A)Remove the cap screws holding the gearmotor case halves together and pry the two cases apart.

B)To lift off the cover, lift up until you can feel internal contact, then pull the cover towards the output gear end, and then

lift the cover (with drive motor attached) up and away from the gear motor case.

Note: The case cover output gear, bearings, and shaft are one pressed together assembly. Replace as a unit.

C)Inspect the oil, gears, and bearings. If the oil level and condition is acceptable,
