Failure Mode: This mode will last indefi nitely until the failure is corrected. The Service Button,
(not on all models) will reset the failure mode.
NOTE: If the Clean LED is fl ashing 3 blinks, look for an evaporator thermistor that has not reached
52°F. This may be due to a loose or improperly positioned thermistor, a hot gas failure, a sealed
system leak or restriction.
The bin thermistor is constantly checked during the Flush, Idle, and Harvest Modes, and the
end of each Freeze Mode. If the LED is fl ashing 2 blinks, look for a disconnected or open bin
thermistor.
