To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit, unless test
procedures require power to be connected. Discharge capacitor through a resistor before attempting to service.
Ensure all ground wires are connected before certifying unit as repaired and/or operational.

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 back
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.
Colder freezer settings and free air space
around the ice maker to let air circulate will
help make ice faster. After the ice forms, the
ice maker continues to wait until it reaches
15ºF before it
starts the harvest cycle. This ensures that
the ice is solid in all the cavities. At 15ºF 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.
Just before the ejector completes the second
revolution, the ice maker turns the water
valve on for approximately 7 seconds and
refills the mold with approximately 4 ounces
of water and the freezing cycle is ready to
begin again.
To access the ice maker, open the freezer
door, remove bottom cover and the ice maker
is accessible.
To access module, motor, and support
assembly loosen screws in module access
ports, disconnect shutoff arm, disconnect
wiring harness and remove mold from
support assembly.
