Troubleshooting
(Note: All wire colors are subject to change)
Problem Possible Cause Possible Solution
Ice Flaker will not run
1. Unplugged or defective Photo Eye(s). 1. Ensure Molex plugs are properly and securely connected. Place a wire jumper
between terminals #10 (blue) and #11(black) at the Level Control Relay (LC1). If Ice
Flaker starts, Photo Eyes may be defective and need to be replaced.
2. Defective Level Control Relay (LC1). 2. Place a wire jumper between terminals #5 (red) and #6 (red) at the Level Control
Relay (LC1). If Ice Flaker starts, Level Control Relay (LC1) may be defective and
need to be replaced.
3. No control power from Transformer (T1). 3. Check voltage across Term 1 (purple) and Term 2 (yellow/orange) at Control
Module (CM). If 24 VAC not present, Transformer (T1) may be defective and need
to be replaced.
4. Open switch or loose wiring. 4. Place a wire jumper between Term 2 (yellow/orange) and Term 3 (red) at Control
Module (CM). If Ice Flaker starts, trace voltage from Term 3. Check all wire
terminals and tighten as necessary.
5. Defective Control Module (CM). 5. Place a wire jumper between Term 2 (yellow/orange) and Term 3 (red) at Control
Module (CM). If Ice Flaker does not start, Control Module (CM) may be defective
and need to be replaced.
Ice Flaker does not
shut down when
Ice Bin is full
1. Defective Emitter Photo Eye. 1. Unplug Emitter Photo Eye and wait longer than Off ‐ Delay setting. If Ice Flaker
stops, Emitter Photo Eye may be defective and need to be replaced.
2. Defective Receiver Photo Eye. 2. Unplug Receiver Photo Eye and wait longer than Off ‐ Delay setting. If Ice Flaker
stops, Receiver Photo Eye may be defective and need to be replaced.
3. Level Control Relay (LC1) is jumped out. 3. Check for a wire jumper between terminals #5 (red) and #6 (blue) at Level Control
Relay (LC1). If present remove wire jumper.
4. Defective Control Module (CM). 4. Remove wire from Term 3 (red) at Control Module (CM) and wait longer than Off ‐
Delay setting. If Ice Flaker does not stop, Control Module (CM) may be defective
and need to be replaced.
Solenoid Valve will not open
1. Defective Control Module (CM). 1. Verify 24 VAC present across Term 1 (purple) and Term 3 (red) at Control Module
(CM). Remove wires and check for continuity between Term 7 (black) and Term 8
(red). If the contacts remain open, Control Module (CM) may be defective and
need to be replaced.
2. Defective Solenoid Valve. 2. Verify control voltage at Solenoid Valve wire leads. If voltage is present, Solenoid
Valve may be defective and need to be replaced.
3. Defective Motor Relay (R1). 3. Place a wire jumper between terminals #6 (yellow) and #7 (black) at Motor Relay
(R1). If Solenoid Valve opens, Motor Relay (R1) may be defective and need to be
replaced.
4. Loose wiring. 4. Check all wire terminals and tighten as necessary.
