IF SERVICE IS REQUIRED
If you do not understand a troubleshooting remedy, or
your product needs service, contact U-Line Corporation
directly. Contact information appears on the rear cover of
this guide.
When you call, you will need your product Model and
Serial Numbers. This information appears on the Model
and Serial number plate located on the upper right or rear
wall of the interior of your product.
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
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.
