Troubleshooting Guide
17
The cabinet temperature is too warm.
The condenser coil may be clogged with dust,
grime or debris. Clean it following the instructions in
Chapter 6.
The door or door gasket may not be sealing properly.
Check product placement in the cabinet as it may
prevent the door from fully closing. If the gasket is
loose, reattach.
The temperature may be set too high. Adjust the
setting to 35.0°F (2.0°C) for refrigerators or -4.0°F
(-20.0°C) for freezers.
Hot food items may have been placed in the cabinet.
Store only room temperature food items.
The room’s ambient temperature may be higher than
86°F (30°C). Provide ample ventilation or additional
cooling to the room. Relocate the unit from extremely
small spaces without ventilation.
The unit may be installed in close proximity to heat
sources such as ovens, stoves, heaters or direct
sunlight. Relocate the unit away from these sources.
The unit may be installed without clearance or
proper ventilation. Provide additional exhaust vents
and observe the clearance allowance specified in
Chapter 2.
Food items are frosting over.
The temperature may be set too low. Adjust the setting
to 35.0°F (2.0°C) for refrigerators or -4.0°F (-20.0°C)
for freezers.
The placement of food items in the cabinet may be
obstructing circulation of refrigerated air. This creates
uneven temperature in the cabinet with pockets of
very cold air that may cause items to frost or freeze
over. Food items must not touch the wall or floors of
the cabinet and stay within the boundaries of the shelf
to prevent blockage of air flow.
Condensation in the interior cabinet.
The door / drawer or gaskets may not be sealing
properly. If the gasket is loose, reattach. Check product
placement in the cabinet as it may prevent the door
from fully closing.
Hot food items may have been stored in the cabinet.
The interaction between hot and cold temperatures
will promote condensation.
Unsealed or open food items with high moisture
content may have been stored in the cabinet. Keep
these items in air tight containers.
Mild condensation in warmer ambient temperature
conditions may occur due to frequent or prolonged
door operation.
Condensation on the unit’s exterior
surfaces.
Highly humid environments will contribute to the
condensation build up on exterior panels. Providing
ample ventilation and air movement to a space will
reduce the humidity level.
The door, drawer or gasket may not be sealing
properly. Check product placement in the cabinet as it
may prevent the door from fully closing. If the gasket is
loose, reattach.
Noise level during unit operation.
It is normal for commercial grade compressors and
components to have a higher decibel output compared
to residential counterparts.
The unit may not be balanced evenly. Poorly leveled
units may cause components or fittings to misalign or
disengage during operation. This may produce noise
as a direct result of repeated surface friction or impact.
The unit may not be securely mounted to the floor.
This may produce noise as a direct result of repeated
surface friction or impact.
Some sounds are normal for the refrigeration
process. A dripping sound, for example, is the result
of refrigerant circulation during the compressor rest
period.
