LIQUID LINE

Ice will build up in the bin until it contacts the bin level probe. After ice contacts the bin level probe for 30 continuous seconds the liquid line solenoid valve de-energizes. To allow excess ice to run out, the gear motor and the water float valve solenoid remain energized for an additional 4 minutes, then de-energize.
