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 ice
machine 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.
