TO REMOVE AND REPAIR THE GEARMOTOR ASSEMBLY
(Assuming that the procedures through removal of
the water seal have been performed.)
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.
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, quickly
check the gears and bearings. They
are likely to be fine if the oil is.
If there is evidence of water in the
oil (rusty bearings and gears; the oil
having a creamy white appearance;
oil level too high) carefully inspect
the bearings and gears. If in doubt
about the condition of a part,
replace it. The oil quantity is 14 fluid
ounces, do not overfill.
Note: The gears and bearings are
available only as pressed together
sets.
D) After replacing parts as required, (if any)
reassemble the gearcase. The two smaller gears
and the oil should be in the lower case, the output
gear will be with the cover. As you lower the cover
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.
