Harv est: During the harvest cycle the compressor is still operating, but the water pump
has stopped. Two other components have been energized: the hot gas valve and the water
inlet valve. These two valves open and warm up the freezing surface, allowing the cubes to
fall into the bin. The freeze cycle will restart when all the cubes have been harvested.

freezing portion of the ice-making cycle, the water in the sump will become highly
concentrated with mineral impurities.
During the harvest cycle, fresh water flows into the machine to dilute the bin water and
rinse the concentrated minerals down the drain.

Your new ice maker may make sounds that are not familiar to you. Most of the new
sounds are normal. Hard surfaces like the floor and walls can make the sounds seem
louder than they actually are. The following describes the kinds of sounds that might be
new to you and what may be making them.
•
You will hear a swooshing sound when the water valve opens to fill the water sump
for each cycle.
•
Rattling noises may come from the flow of the refrigerant or the water line. Items
stored on top of the ice maker can also make noises.
•
The high-efficiency compressor may make a pulsating or high-pitched sound.

The ice maker
begins with a fixed
charge of water that
is contained in the
water sump. As the
water is sprayed
against the freezing
evaporator surface,
the portion of water
that does not contain
mineral impurities
will freeze and stick
to the ice cube molds.
The water containing
impurities falls back
into the water sump.
