12. Anti-Slush (S5 dip switch 5)
This dip switch setting provides anti-slush control during the freeze cycle. When the
evaporator temperature reaches 36°F (2.2°C) the control board reads a 5.8 kΩ signal
from the thermistor and de-energizes the water pump for 10 sec. to melt the ice slush
and prevent the ice slush from blocking the water supply tubing, causing irregular freeze
patterns.
NOTICE
Factory set for proper operation. Do not adjust. Adjustment outside the factory
default setting may result in damage to the appliance.
