3A. ICE RUN OUT
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 compressor
de-energizes. To allow excess ice to
run out, the gear motor and the water
float valve solenoid remain energized
for an additional 45 seconds, then
de-energize.
