the outside. No ice
production.

compressor, gearmotor and
fan motor running.
8. Compressor cycles
intermittently.
System status: gearmotor
and fan motor run.
9. Unit runs but not making
ice.

Troubleshooting chart
1. O ring seal broken.
1. Kink in ice transport tube.
2. Bin level control remains in closed
position.
3. Ice transport tube ruptured internally.
4. Worn evaporator bearings.
5. Faulty centrifugal switch. Icemaker
torques out within 5 seconds of start-up.
6. Torque out occurs when storage bin fills
to capacity.
1. Gearmotor running but no output
rotation.
2. Float reservoir empty.
1. Compressor start relay in wrong
position.
2. Intermittent voltage from circuit board to
compressor.
3. Clogged or dirty condenser coil.
4. Improper ventilation.
5. Defective compressor.
1. Clogged or dirty condenser coil.
2. Compressor not pumping.
3. Low refrigerant charge.
1. Compressor switch in OFF position.
2. No output on compressor and fan motor
terminals on control board.
1. Replace O ring.
1. Eliminate kink and check that tube
routing complies with Follett
icemaker installation manual.
2. Adjust or replace control.
3. Replace complete run of ice
transport tube.
4. Inspect bearings for roughness or
binding and replace if necessary.
5. Replace centrifugal switch.
6. Ensure that ice contacts bin
thermostat before backing ice up in
transport tube. Reference dispenser
manual for proper thermostat and
ice tube mounting.
1. Check for broken gearmotor output
shaft or damaged gearbox.
2. Check for defective water sensor
(water OK (WTR) LED remains on
even when float empty or probe
removed from water).
1. Position relay with arrow or word
"top".
2. Check for constant line voltage
output on board compressor
terminal and replace board if
intermittent.
3. Clean condenser coil.
4. Provide inlet and exhaust air
provisions per Follett icemaker
installation manual.
5. Replace compressor.
1. Clean condenser coil.
2. Replace compressor.
3. Check for leaks; repair, evacuate,
and weigh in correct charge.
1. Turn compressor switch on.
2. Replace control board.
