below to help you quickly identify common problems

or your product needs service, contact U-Line
Corporation directly at +1.414.354.0300
When you call, you will need your product Model and
Serial Numbers. This information appears on the Model

NORMAL OPERATING SOUNDS
All models incorporate rigid foam insulated cabinets to
provide high thermal efficiency and maximum sound
reduction for its internal working components. Despite
this technology, your model may make sounds that are
unfamiliar.
Normal operating sounds may be more noticeable
because of the unit’s environment. Hard surfaces such
as cabinets, wood, vinyl or tiled floors and paneled
walls have a tendency to reflect normal appliance
operating noises.
Listed below are common refrigeration components
with a brief description of the normal operating
sounds they make. NOTE: Your product may not
contain all the components listed.
•
Compressor: The compressor makes a hum or
pulsing sound that may be heard when it operates.
•
Evaporator: Refrigerant flowing through an
evaporator may sound like boiling liquid.
•
Condenser Fan: Air moving through a condenser
may be heard.
•
Automatic Defrost Drain Pan: Water may be heard
dripping or running into the drain pan when the
unit is in the defrost cycle.
