How unit works — lever models
The dispense wheel motor and dispense solenoid are energized through the power and ice dispense switches. The water
solenoid valve is energized through the power and water dispense switches. The icemaker receives the bin signal through
the power switch, the normally closed bin thermostat and the icemaker switch.
When the bin level thermostat is calling for
ice, a 115V bin signal is applied to the bin signal terminals on the icemaker circuit board.
When ice builds up around the bin
thermostat, the contacts open, cutting the bin signal to the icemaker.
