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
CHECK
POSSIBLE CAUSE
REMEDY
Placement of glass
shelves in cabinet interior.
Do not space the glass
shelf out away from the
molded in liner shelf
supports on the back of
the cabinet interior the
cold air from the
evaporator can be
“trapped” above the shelf
resulting in the area
above the shelf becoming
too cold and below too
warm (This applies to
models with glass shelves
only).
Properly place the glass
shelves in the unit. White
rubber “shelf bumper”
must be placed so as to
create a air space gap
between the rear edge of
the glass shelf and the
molded shelf supports on
the back of the cabinet
interior.
Interior too warm
(compressor operates).
Thermostat
Thermostat set to too low
(warm) of a setting.
Adjust thermostat to a
colder setting (higher
number on knob).
Thermostat failed, cutting
compressor off too soon.
Replace thermostat. Leak
check the sealed.
Refrigeration system.
Locate and correct the
source of the leak.
Replace the drier and
recharge to proper
amount.
The evaporator for the
presence of a frost
pattern. If frost not present
with compressor
operating.
Refrigerant leak.
Leak check the sealed
refrigeration system.
Locate and correct the
source of the leak.
Replace the drier and
recharge to proper
amount.
High and low side
pressures in the sealed
system.
Compressor valve failure,
preventing compressor
from developing required
refrigerant pressures for
system operation.
Replace compressor and
drier, evacuate and
recharge with refrigerant
to the proper amount.
Restriction in the sealed
refrigerant system causing
high compressor
discharge pressures and
low pressures or vacuum
conditions on the suction
side. Pressure does not
equalize quickly when the
compressor is turned off.
Locate the restriction and
correct the cause.
Evacuate, replace drier
and recharge the sealed
refrigeration system to the
proper level.
