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.

WARNING

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.
