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 signifies 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 signifies 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.
HOLIDAY MODE
The Holiday Mode feature is designed for the traveler or for those whose religious observances require turning off the lights and the ice maker. By selecting this feature, ice production and the interior lights will be disabled. Press and hold the Holiday Mode button to turn on the Holiday Mode feature. Press and hold the button again to turn off the feature.
The Holiday mode LED is lite constantly in this mode.
