Normal operation – Stage 3
The gearmotor comes up to its normal running speed and the centrifugal switch located in the gearmotor opens,
dropping out the start winding. As the compressor comes up to normal running speed, the compressor start relay
contacts 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 satisfied. The 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 LED (C), compressor, and
fan motor go off. (Should the ice level control not remain open for 10 seconds, the ice maker 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.
