and "DRAIN."
a) ICE
When the control switch is in the "ICE" position, the control switch closes a 5VDC
circuit from control board K4 connector pin #3 (W/R) to control board K4 connector
pin #4 (W/R). When the control board receives 5VDC on K4 connector pin #4 (W/R),
the control starts the icemaking process.

c) DRAIN
When the control switch is in the "DRAIN" position, the control switch closes a 5VDC
circuit from control board K4 connector pin #1 (W/BK) to control board K4 connector
pin #2 (W/BK). When the control board receives 5VDC on K4 connector
pin #2 (W/BK), the control board directs 24VAC to the drain valve and the drain valve
energizes.
