Used for adjustment of the defrost timer. The defrost timer starts counting when the
thermistor reads a certain temperature at the evaporator outlet.

Used for adjustment of the drain timer. When a freeze cycle is completed, the pump
motor stops, and the icemaker resumes operation in 2 seconds. Then the pump motor
drains the water tank for the time determined by the drain timer. The drain timer also
determines the time to restrain completion of a defrost cycle, i.e. the minimum defrost
time.

frequency determined by the drain counter.

The freeze timer determines maximum
freeze cycle time. Upon termination of

harvest cycle. After 2 consecutive timer
terminations, machine will shut down,
possibly indicating a problem.
