Normal operation – Stage 2
The water sensor verifies water in the float. 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 compressor is started through a current style relay that is pulled in by the initial high current draw of the
compressor. The gearmotor start windings are also energized through a current relay. The B-E 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, dropping out
the start winding of the compressor. The icemaker is now in a normal icemaking mode. The icemaker will produce
ice until the bin level control in the ice dispenser is satisfied. The B-E, DR, C and WTR LEDs are all on.
