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

 

Interior too cold or 
contents freezing. 

Thermostat setting 

Thermostat set to too cold 
of a setting for ambient 
conditions. 

Adjust thermostat warmer 
setting (lower number on 
knob). 

 

The evaporator for the 
presence of a uniform 
frost pattern. Is the frost 
confined to left wing and 
the left side of the back? 

Note:

 Compressor should 

be operating for least 5 
minutes with door open to 
perform this check. 

Refrigerant leak or low 
refrigerant charge in the 
sealed system. 
Refrigerant volume in 
evaporator is not sufficient 
to cool the region of the 
plate where the 
evaporator plate sensing 
thermostat’s thermo bulb 
mounts. Therefore the 
control thermostat never 
reaches its cutout 
temperature and the 
compressor operates 
100% of the time. The 
remaining evaporator 
volume is sufficient to cool 
the air temperature below 
freezing. 

Locate and correct cause 
of refrigerant leak. 
Replace drier, evacuate 
and recharge sealed 
refrigerant system with the 
proper amount of charge 
as listed on the unit’s data 
plate. 

 Thermostat 

(compressor 

control) thermo bulb 
mounting or routing. 

Mounting location 
incorrect. Model should be 
on the right wing of the 
evaporator plate. All other 
models mount at the rear 
top center of the 
evaporator. 

Relocate thermo bulb to 
proper location. 

 

 

Thermostat sensing tube 
(capillary tube) resting on 
or above compressor 
dome in mechanical 
compartment causing 
false sensing. 

Reroute sensing tube 
clear of compressor dome 
area. 

 

 

Thermostat thermo bulb 
mounting bracket not 
secure, causing false 
sensing. 

Securely tighten thermo 
bulb mounting bracket. 

  Insufficient 

thermo 

bulb 

contact area on 
evaporator U-shaped loop 
with 3-inch long legs 
required. Bracket should 
be located at mid point of 
each 3-inch leg. Both legs 
secured under bracket. 

Adjust thermo bulb contact 
area to achieve sufficient 
contact. A U-shaped loop 
with 3-inch long legs is 
required. The mounting 
bracket should be located 
at the mid-point of each 3-
inch leg.  Both legs 
secured under bracket.
