Normal operation – Stage 2
The water sensor verifi es water in the fl oat reservoir. The water OK LED (WTR) comes on. At the same time, the
gearmotor, compressor and condenser fan motor come on, lighting the drive LED (DR) and compressor LED (C).
The gearmotor is started through a current style relay that is pulled in by the initial high current draw of the run
winding. The compressor is started with the start winding being energized through the normally closed contacts of
the potential relay, starting capacitor, and the run capacitor. The PWR, BE and WTR LED remain on.

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 open and the starting
capacitor drops out. The start winding remains energized through the run capacitor. 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.
