ERROR DISPLAYS
These errors will occur at any time during normal operation if a thermistor fails.
2 Blinks — Service Light is blinking twice in repeating intervals – This signifi es a bin thermistor
failure. Check that the bin thermistor is plugged in to the control box. Check that the bin thermis-
tor is not open or shorted. Replace the thermistor if it is open or shorted.
3 Blinks — Service Light is blinking three times in repeating intervals – This signifi es a harvest
failure. Check that the evaporator thermistor is connected to the sealed system tubing. If the
thermistor is plugged in, ensure that it is fully connected to the control box. (The ice maker will
operate on a timed cycle if the evaporator thermistor is unplugged.) Check the resistance of the
thermistor. If the thermistor checks good, then look for a frost pattern on the evaporator plate.
The unit may be low on refrigerant.
