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.
