Section 3 - Service and Repair

Too much ice

Ensure the bin arm is correctly moving during an ice production cycle and that it can touch the top of the ice. If not, the arm may have been bent.

Excessive frost on evaporator

Force a defrost cycle via the keypad input. If the evaporator clears it was due to some type of abnormal operation. If the unit will continue to be used in this manner the defrost length can be lengthened in the service menu to prevent future issues. Extending this length may be detrimental to the freezer section by causing food to melt or ice to fuse more easily.

During the forced defrost, if no heating occurs, check the hot gas coil and heater for voltage and resistance.

Noise

These are frost-free units with two fans, compressor, and two solenoid valves. Some noise is normal such as a hum from the fans/ compressor. Also, during an ice harvest it is normal to hear water filling the mold and cubes dropping into the bucket.

Poor ice quality

This can be caused by poor incoming water quality.

Display is showing something other than “SP (38)” or “ER.”

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 accidentally 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.
