Troubleshooting
To avoid risk electrical shock, personal injury, or death,
always disconnect electrical power source to the freezer
before attempting to service, unless test procedures require
power to be connected. When removing any wiring from terminals they must be replaced on the same terminals.
Ensure all ground wires are connected before certifying unit as repaired and/or operational.

PROBLEM POSSIBLE
CAUSE CORRECTION
Unit does not operate.
The unit is unplugged.
Plug in the unit.
Breaker is tripped or fuse is blown.
Reset breaker or replace fuse. Check to make sure
there is not a short in the electrical circuit.
Ice machine selector switch is in the "OFF"
position.
Set the rocker switch on the grille of the ice machine
to the "ON" position.
The evaporator and/or bin thermistors are
out of specification.
Test the thermistor in question (see section 5.2 on
thermistor and testing). Replace any thermistor that
is out of specification.
Unit operates but does not produce
any ice.
The unit has just been started and it has
been less than 6 hours.
Ice produced when the unit is initially started will
melt off in the bin. Ice will accumulate in the bin. In 6
hours there can be a few cubes in the bin. This is
normal operation.
Typical ice production cycle can take up to
1.5 hours. Initial startup cycles can be
longer.
Check the unit in 24 hours for ice accumulation in
the bin.
The selector switch is in the "OFF" or
"CLEAN" position.
Set the rocker switch on the grille of the ice machine
to the "ON" position.
Build up of deposits on evaporator plate.
See "CLEANING YOUR ICE MACHINE" section for
cleaning the unit for proper operation.
Distributor tube is restricted or not installed
correctly.
See "CLEANING YOUR ICE MACHINE" section for
cleaning the unit for proper operation.
Grid cutter is unplugged.
Plug in the grid cutter so that ice slabs can be cut
into cube.
No water in the reservoir.
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.
Inadequate drain system.
Restriction in drain lines will cause ice in the bin to
melt. If using a gravity drain, make certain there are
no kinks or restrictions in the drain lines. If using a
drain pump, check the inlet screen, discharge line,
and vent line for any build or restrictions.
Condenser fan airflow is restricted.
Make certain the grille in the front of the unit is free
and open for proper air circulation. Check and clean
the condenser coil by removing the grille in the front
of the unit. Clean the condenser with a vacuum and
brush attachment.
Room and/or water temperature is too warm. Move the unit to an area where ambient temperature
is below 90 deg. F. The unit should not be placed
next to a heat source such as an oven. Check for
cold-water connection.
Leaking drain valve.
See "CLEANING YOUR ICE MACHINE" section for
cleaning the unit. This will also dissolve and flush
out foreign material in the drain valve causing it to
leak. If this does not stop the drain valve from
leaking, the drain valve will need to be replaced.
Evaporator thermistor does not have
sufficient contact with evaporator.
Check to see that the evaporator thermistor is
secured properly. If there is any noticeable gap
between surfaces, use a heat sink compound as
specified in section 5.2.
Leak in sealed system.
Check for any leaks, repair leak, evacuate and
recharge unit.
