Switch Nos. 1 and 2:

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.

Switch Nos. 5 and 6:

Used for adjustment of the drain counter. The pump motor drains the water tank at the frequency determined by the drain counter.

Switch Nos. 7 and 8:

Used only for checking the controller board. Usually set in OFF position.

Switch Nos. 9 and 10:

Used for adjustment of freeze timer. The freeze timer determines maximum freeze cycle time. Upon termination of freeze timer, machine initiates the harvest cycle. After 2 consecutive timer terminations, machine will shut down, possibly indicating a problem.
