Normal operation – Stage 3

After the initial high current draw drops off, the gearmotor start relay contacts open, dropping out the start winding. As
the compressor comes up to normal running speed, the compressor start relay contacts also open, dropping out the
start winding of the compressor. The icemaker is now in a normal icemaking mode. The icemaker will begin to produce
ice and continue to produce ice until the bin level control in the ice dispenser is satisfi ed. The PWR, B-E, DR, C and
WTR LEDs are all on.

Normal operation – Stage 4

Once the ice level control opens, the B-E LED goes out. After a 10 second delay the compressor LED (C), compressor
and fan motor go off. (Should the ice level control not remain open for 10 seconds, the icemaker will continue to run.)
The gearmotor continues to run and the DR LED remains lighted for 60 seconds. The purpose of this function is to
drive the remaining ice out of the evaporator and to boil off any refrigerant remaining in the evaporator. The bin timer
LED (BT) comes on, starting the twenty minute off cycle time delay.
