TO REPLACE BEARINGS
Disconnect power to the unit before servicing. Follow all lock out/tag out procedures established by the user. Verify all
power is off to the unit before performing any work.
Failure to comply could result in serious injury, death or damage to the equipment.
1. Dispense all ice from unit.
2. Remove panels.
3. Unplug Dispense Motor and Ice Level Switch.
4. Remove four screws holding dispense cover in place.
5. Remove dispense cover assembly.
6. Use an open end wrench on auger nut connected to bearing and turn and turn counterclockwise to remove
assembly.
7. Remove worn bearings. Replace with new bearings and then reinstall assembly.
NOTE: If auger turns with nut, remove cover on top of gear motor stator and hold rotor while loos-
ening nut.
8. Reconnect power to icemaker.
TROUBLESHOOTING COMPRESSOR
Basically the compressor problems can be narrowed down to three areas of checkout.
1. THE COMPRESSOR WILL NOT RUN
• No voltage to the compressor terminals - check circuit.
• Low voltage - below 90% of nameplate rated voltage.
• Problems in the compressor electrical circuit. See Electrical Checkout Instructions.
2. THE COMPRESSOR STARTS BUT TRIPS REPEATEDLY ON THE OVERLOAD PROTECTOR
• Check for proper fan operation and clean condenser.
• Check the compressor suction and discharge pressures.
• Voltage - The voltage should be within 10% of the rated nameplate voltage.
• High compressor amperage draw, it should never exceed 120% of the rated nameplate amperage. See
Electrical Checkout Instructions.
3. THE COMPRESSOR RUNS BUT WILL NOT REFRIGERATE
• Check the compressor suction and discharge pressures. See Chart on Page 12.
ELECTRICAL CHECKOUT
1. Be sure the unit is disconnected from the power source. Remove the compressor electrical box cover. Check
for obvious damage and loose wires.
2. Disconnect the fan motor leads. Since capacitors store energy, short the capacitor with a screwdriver. This will
prevent shocks.
3. Disconnect the compressor terminal wires.
