Ice machine disposition Possible causes Corrective action
FLASHING ON or OFF
Legend:
OFF ON
1. Ice machine is in running
condition but not making ice.
.
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.
7. Machine in Purge cycle. 1. Replace compressor.
2. Replace start relay.
3. Replace start capacitor.
4. Replace run capacitor.
5. Replace main contactor.
6. Replace PC board.
7. Check for Purge operation.
2. Machine in TIME DELAY without
full bin.
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. Correct transport tube routing.
2. Repair or replace shuttle
mechanism.
3. Replace or reposition
thermostat.
4. Correct coupling installation.
3. Ice machine is not making ice.
HI AMPS.
.
1. Poor water quality causing ice to
jam auger.
2. Damaged shuttle mechanism.
3. Intermittent drive output from
PC board. Evaporator will freeze
causing a HI AMPS error.
4. Gearmotor is unplugged.
1. Clean ice machine. Increase
fl ushing frequency.
2. Replace or repair shuttle
mechanism.
3. Replace PC board.
4. Plug in gearmotor.
4. Ice machine is not making ice.
HI PRESSURE.
.
1. High ambient temperatures
>100 F (38 C).
2. Poor ventilation or air
recirculation.
3. Clogged condenser (air-cooled).
4. No water fl ow through condenser
(water-cooled).
5. Fan not working properly. No
air fl ow.
• Blocked fan blades
• No fan output from PC board
• Faulty fan motor
1. Air condition area to below
100 F (38 C).
2. Reposition ice machine or
properly ventilate. Prevent
ice machine exhaust from
recirculating.
3. Clean condenser grille (air-
cooled).
4. Restore water fl ow to condenser.
5. Correct air fl ow.
• Remove any blockage from
fan blades
• Replace PC board
• Replace fan motor
5. Ice machine is not making ice.
Drain clog.
.
1. Drain hose kinked or plugged
causing water to back up.
2. Improper fl oor drain routing/pitch
causing water to back up.
3. High TDS levels and leaking
drain solenoid may cause an
errant drain clog.
4. No vent on external drain line.
1. Remove kink or blockage from
drain hose.
2. Re-route fl oor drain.
3. Clean area around drain sensor
and/or replace Drain solenoid
valve.
4. Add vent to drain line.
