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.

The pump motor drains the water tank at the frequency determined by the drain counter.
Switch Nos. 7 and 8:
