Replacement Parts
When you need replacement parts, always request genuine U-Line
replacements. U-Line designs and engineers products using
components that work efficiently, and provide superior service life
and performance. The use of aftermarket parts or components
may affect the safety, operation, performance or durability of your
product, and may also void its warranty.
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.
