AUGER & EXTRUDING HEAD REMOVAL
FIGURE 9. UPPER NUT AND BEARING
The upper bearings located on top of the auger is used to absorb the force between the auger and extruding
head.
The bearings are 3/32” thick. When they wear below 1/16” they should be replaced. Bearings to be
inspected for wear during quarterly maintenance. See Figure 9.
TO REPLACE BEARINGS
1. Dispense all ice from unit.
2. Disconnect unit from electrical power.
3. Remove panels.
4. Unplug Dispense Motor and Ice Level Switch.
5. Remove four screws holding dispense cover in place.
6. Remove dispense cover assembly.
7. Use an open end wrench on auger nut connected to bearing and turn and turn counterclockwise to remove
assembly.
8. 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 loosening nut.
9. 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
A.
No voltage to the compressor terminals – check circuit.
B.
Low voltage – below 90% of nameplate rated voltage.
C.
Problems in the compressor electrical circuit. See Electrical Checkout instructions.
2. THE COMPRESSOR STARTS BUT TRIPS REPEATEDLY ON THE OVERLOAD PROTECTOR
A.
Check for proper fan operation and clean condenser.
B.
Check the compressor suction and discharge pressures.
C.
Voltage – The voltage should be within 10% of the rated nameplate voltage.
D.
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
A.
Check the compressor suction and discharge pressures. See Chart on Page 10.
