U-Line 2115R, 2275DWRWS, 2175WCOL, CO2175F Display is showing something other than SP 38, ER or CL

Section 3 - Service and Repair

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 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 cooler 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 process 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 equipped, 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 stand pipe 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 CLRCO2175 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 “SP (38),” “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 returns 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 LIGHT 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.

Refrigerator not cooling but ice maker working

Check to ensure the refrigerator thermistor is working properly.

Ice maker not operating—no water flowing over mold

The refrigerator needs to be at or below set-point (or 42°F) to start the ice-making process. If the unit is cool enough there could be a defective bin thermistor, defective condenser thermistor or defective solenoid coil.
