How the Ice Maker Produces Ice

After the unit is powered on, the ice maker rotates the ice case into the 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 produces bullet shaped ice
around the evaporator.
When a batch of ice has 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 the ice cube bullets to slide off the evaporator. The ice shovel will push this ice into the
ice basket and 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 and the water will
be reused. Once enough of the ice has melted, the ice maker will automatically start making more ice.

Normal Sounds

The ice maker may make sounds that are not familiar to you. Most of the new sounds are normal.
Hard surfaces like the floor, 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.
• 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.
