Normal operation – Stage 3

After the initial high current draw drops off, the gearmotor start relay contacts open, dropping out the start winding (or 
start capacitor). 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.
