TROUBLESHOOTING (CONTINUED)
No ice
Check the ice bin temperature. If the temperature is in the 34-
35°F range, the unit is shut down due to low temperature inside.
This could be caused by low ambient temperatures or running the
unit without a water supply attached.
If the ice bin temperature is above 35°F, the unit should be
producing ice. Check to ensure the water trough is full and the
pump is operating.
Too much ice
Ensure there is Permagum around the thermistor hole. If there is,
proceed to the next step.
The control board is equipped with an adjustment to adjust the
level of ice in the bin for customer preference or when used in
abnormal installations. With ice stacked to the desired level, check
the bin temperature by holding WARMER and COLDER for five
seconds. We’ll assume the display showed 38°F for this example.
Go to service mode #24 and adjust the setting to that number.
This will allow the bin to shut off at this ice level. This temperature
needs to be checked after the door has been closed for at least 10
minutes in order for the thermistor temperature to stabilize.
Too little ice
If this is a recurring issue, try adjusting service option #24 colder in
1 or 2° increments until the desired level of ice is achieved.
Ice not sized to customer satisfaction
The thickness of the cubes can be adjusted per the ice thickness
section of the manual.
Noise
Some noise from this unit is normal. You may hear the sound of ice
dropping into the bin, especially when it is empty. The harvesting
processes involves flowing refrigerant and water through valves
which may produce a rushing type sound during the harvest. The
fan and compressor will produce a continuous low motor noise. If
installed, the P60 pump will produce noise at regular intervals as it
empties water from the unit. If any of these is objectionable, the
unit has an Office mode which can be entered for three hours at a
time. During this mode the unit will not produce ice; however, the
drain pump will continue to operate.
No water in trough
Ensure the standpipe is fully inserted into the trough.
Check the water valve to see if it is filling the unit.
Watch the water flow over the mold to see if excess water is being
splashed out of the trough. This could be the result of improper
leveling.
Ice does not release from evaporator
This could be caused by improper leveling or the unit is in need of
cleaning.
Poor ice quality
This can be caused by poor incoming water quality. The CLR2160
is designed to produce clear ice in most water; however, abnormal
water conditions may result in the need for further filtering.
Water in ice bin
A defect in the drain from the unit will cause water to stop
draining from the unit.
Display is showing something other than “Ice,” “ER”
or “CL.”
Push one of the keys to see if the display is reset.
Turn unit on and off via the display pad.
Unplug unit, wait one minute and plug back in. If any of these steps
return the unit to operation the unit was probably accidently
entered into a service mode.
Display is showing a random snaking of characters
or a degree symbol is flashing.
The unit is in a special showroom mode. Hold the COLDER key
and press the LIGHT key three times to exit.
Display not illuminating but unit operating
First try to plug and unplug the unit. If the display still does not
illuminate, there is a four-wire pin connector running from the
main board in the base to the display board. One of the wires is
disconnected or damaged.
Unit is not operating—no cooling—no fans.
Unplug unit and plug back in. If main board beeps when plugging in
the unit then this is most likely a system problem not a board issue.
If board does not beep when plugging in the unit, check the power
supply to ensure the outlet is working. Also, check the fuse on the
circuit board.
