the CONTROL OPERATION section to clearly understand
the function of the control.
If the problem persists, read the NORMAL OPERATING
SOUNDS and TROUBLESHOOTING GUIDE sections below
to help you quickly identify common problems and
possible causes and remedies. Most often, this will resolve
the problem without the need to call for service.
If your product needs service, please go to
www.u-line.com/servicers/ and navigate to the Find a

handy; They can can be found on the Serial number plate
located within the interior of your product, most often
placed on the ceiling.
All models incorporate rigid foam insulated cabinets to
providehighthermaleciencyandmaximumsound
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,

the part in question. The part that caused the damage
must be returned to U-Line in its entirety. The part must
be clearly labeled with the serial number of the unit it was
removed from, the date, and the servicer who removed the
part.
If the service technician determines the damage is the
