Ice machine disposition
Legend:
ON
1. Ice machine is in running
condition but not making ice.
2. The CPU is not fl ashing.
3. Machine in TIME DELAY without
full bin.
4. Ice machine is not making ice.

5. Ice machine is not making ice.
HI AMPS.
Possible causes
OFF ON or OFF
1. Defective compressor.
2. Defective start relay.
3. Defective start capacitor.
4. Defective run capacitor.
5. Defective main contactor.
6. No output from PC board.
1. Processor has been damaged.
1. Ice jamming due to improperly
installed transport tube causing
a false shuttle.
2. Shuttle stuck in up position.
3. Damaged or improperly installed
thermostat (open).
4. Transport tube backed-out of
coupling.
1. A self-fl ush occurred but could
not drain evaporator due to a
failed drain solenoid valve.
2. A self-fl ush occurred but could
not drain evaporator due to water
reservoir or ice machine not
being level.
1. Poor water quality causing ice to
jam auger.
2. Damaged shuttle mechanism or
thermostat (closed).
3. Kinked transport tube
(thermostat systems).
4. Intermittent drive output from
