TrOuBLESHOOTING GuIdE

POSSIBLE CAUSE
1. The unit is unplugged.
2. Breaker is tripped or fuse is blown.
3. Ice Maker selector switch is in the "OFF"
position.
4. The evaporator and/or bin thermistors
are out of specification.
1. The unit has just been started and it
has been less than six hours.
2. Typical ice production cycle can take
up to one and a half hours. Initial startup
cycles can be longer.
3. The selector switch is in the "OFF" or
"CLEAN" position.
4. Build up of deposits on evaporator
plate.
5. Distributor tube is restricted or not
installed correctly.
6. Grid-cutter is unplugged.
7. No water in the reservoir.
8. Inadequate drain system.
9. Condenser fan air flow is restricted.
Plug in the unit.
Reset breaker or replace fuse. Check
to make sure there is not a short in the
electrical circuit.
Set the rocker switch on the grill of the
Ice Maker to the "ON" position.
Test the thermistor in question (see
Section 5.2, Thermistors). Replace any
thermistor that is out of specification.
Ice produced when the unit is initially
started will melt off in the bin. Ice will
accumulate in the bin. In six hours, there
can be a few cubes in the bin. This is
normal operation.
Check the unit in 24 hours for ice accu-
mulation in the bin.
Set the rocker switch on the grill of the
Ice Maker to the "ON" position.
See "Cleaning Your Ice Maker" section for
cleaning the unit for proper operation.
See "Cleaning Your Ice Maker" section for
cleaning the unit for proper operation.
Plug in the grid cutter so that ice slabs
can be cut into cubes.
Make sure that the reservoir drain plug
is installed. Check the water line to the
unit to make sure it is on and that there
are no restrictions or kinks in the line.
Check all filters to make sure they are not
restricted or plugged.
Restriction in drain lines will cause ice in
the bin to melt. If using a gravity drain,
make certain there are no kinks or restric-
tions in the drain lines. If using a drain
pump, check the inlet screen, discharge
line, and vent line for any build-up or
restrictions.
Make certain the grill in the front of the
unit is free and open for proper air circu-
lation. Check and clean the condenser
coil by removing the grill in the front of
the unit. Clean the condenser with a
vacuum and brush attachment.
