Ice Maker
The unit uses an ice maker that consists of a mold
heater, thermostat, motor, and wire harness. The ice
maker always starts from and stops at the “park”
position. In the park position (the ejector blades
are pointing horizontally towards the side of the
ice maker). Just before reaching the park position
the mold is filled with water. At the park position
all electrical components are de-energized, even
though the shut-off arm is down, and the ice maker
is ready for the next freeze cycle. The ice maker
takes from 30 minutes to one hour to freeze the
water. The primary time factors are the temperature
in the freezer and the amount of airflow around the
ice maker.
By the use of the ice fan assembly, cold air is
directed at the ice maker mold to decrease the time
required to freeze the water in the mold. After the
ice forms, the ice maker continues to wait until it
reaches 15º F before it starts the harvest cycle. This
ensures that the ice is solid in all the cavities. At
15º F the thermostat closes, the mold heater turns
on, and the ejector blades rotate up and forward
until they stall out against the ice. The motor is
designed to stall out and is geared to generate a lot
of pressure. This minimizes the amount of melting
needed to extract the ice. As soon as the ice is
loose enough to move, the ejector pushes the ice
out of the mold during the second half of the first
revolution. During the second revolution the ejector
pushes the ice into the bucket.
To make ice, an ice maker needs power, water, and
sub-freezing temperatures.
Note:
The freezer door switch turns off power to
the ice maker when the freezer door is open. It will
be necessary to manually close the freezer door
switch for some troubleshooting steps. Ensure that
the shut-off arm is down and instruct customer on
its use if necessary.
To access the ice maker:
1.
Open doors and depress button on side of ice
bin assembly and remove.
2.
Insert a screwdriver blade into the slot on harness
cover and bend the inner tab down (1). At the
same time pull the cover forward to release (2).
WARNING
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power to unit using power
switch before servicing. Wires removed during disassembly must be replaced on proper terminals to insure
correct earth ground and polarization. After servicing, reconnect power using power switch.
