Normal operation – Stage 2
The water sensor verifies water in the float 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 high initial current draw of the compressor run winding closes the contacts of the current relay energizing the
start winding through the run capacitor. The gearmotor is also started through a current style relay that is pulled in
by the initial high current draw of the run winding. The PWR, 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 also 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 PWR, B-E, DR, C and WTR LEDs are all on.
