that has not reached 52°F. This may be due to a loose or improperly positioned
thermistor, a hot gas valve failure, a sealed system leak, or a restriction.
The bin thermistor is constantly checked during Flush, Idle, and Harvest Modes, and
at the end of each Freeze Mode. If the LED is flashing in 1 second intervals, look for
a disconnected, or an open bin thermistor.
The Clean switch is continually checked during the Failure Mode, and if pressed, the
program switches to the Service Mode.
