Normal operation – Stage 4
Once the ice level control opens, the B-E LED goes out. After a 10 second delay the LED (C), compressor, and
fan motor go off and the B-T LED comes on. (Should the ice level control not remain open for 10 seconds, the ice
machine will continue to run.) The gearmotor continues to run 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.
