How the Ice Maker Produces Ice

After the unit is powered on, the ice maker begins by rotating the ice case into a horizontal water fill
position under the evaporator. The water pump is engaged and fills the ice case with water. Water
overflows for a few seconds before the compressor turns on. The compressor then pumps refrigerant,
and the fan will turn on automatically after the condenser heats up. The unit then produces bullet-
shaped ice around the evaporator. When a batch of ice has been fully formed, the ice maker stops
the freeze cycle and begins the harvest cycle.
A valve opens, diverting hot refrigerant gas into the evaporator. The gas heats the evaporator,
causing ice bullets to slide off the evaporator. The ice shovel will automatically push the newly formed
ice into the basket and will move the ice case back into the water fill position for the next batch. The
ice maker will produce ice until ice reaches the ice full sensor or until the unit is out of water. The ice
bin compartment is insulated, but not refrigerated and the ice in the bin will slowly melt. Once enough
of the ice has melted, the ice maker will automatically reuse this water to start making more ice.

Normal Sounds

The ice maker may make sounds during operation. Most of these sounds are normal. Hard surfaces
like the floor or walls can make the sounds seem louder than they actually are. The following
describes sounds you might hear and what might be causing them.
• The ice case motor will make a whirling noise when the ice case and shovel are moving.
• Rattling noises may be produced from the flow of the refrigerant.
• The compressor may make a pulsating or high-pitched sound.
• The compressor may also produce a low tone humming sound.
• Water that is being pumped into the ice case will make trickling, dripping or splashing sounds.
• As each cycle ends, you may hear a gurgling sound due to the refrigerant flowing.
• You may hear fan noise and air being forced over the condenser by the condenser fan.
• During the harvest cycle, you may hear the sound of ice cubes falling into the ice basket.
• If the ice maker is run without water, the water pump will make a screeching noise. Note: Do not
run the unit without water!
Notes:
• If the ice maker will not be used for an long period of time, you should unplug the unit
from power, drain the water from the reservoir and dry the interior with a clean soft cloth.
!
• Do not touch the power plug when your hands are wet.
• Do not try to remove the evaporator from the unit.
• Never unplug the unit by pulling on the cord.
