Remove Gear Reducer
Removal
Note: Below steps assume the bin has been removed.
Remove or melt out all ice.
1. Disconnect electrical power to unit.
2. Disconnect wires to auger motor.
3. Remove 3 screws holding motor cover to motor.
4. Remove 4 screws holding rotation sensor holder
to motor.
5. Use a cordless impact driver to remove the screw
holding the magnet rotor. If needed use the
special thin wrench to hold motor shaft.
6. Remove four 1/2” hex head bolts securing
evaporator assembly to gear reducer cover.
7. Remove four 1/2” hex head bolts securing gear
reducer condensate pan to chassis.
8. Separate gear reducer from evaporator and lift it
from the machine.
9. Remove three 1/4 hex socket head screws
securing pan to gear reducer.
Install new gear reducer. Be sure vent plug is open
Gear Reducer
The gear reducer is a sealed component. No gears or
shaft bearings are available. A gear reducer without
motor is available.
A properly operating gear reducer will operate quietly
and draw a consistent amount of amps. It will not leak
lubricant. Oil discharge is a strong indicator of water
infiltration and is cause for replacement.
High amp draw could be caused by scale build up in
the evaporator. Clean it first, then check amp draw.
Confirm the top and lower bearings are not seized or
rough.
A motor that rotates but the output shaft does not turn
indicates a stripped gear and is cause for the gear
reducer section to be replaced.
