Installation Operation and Maintenance Instructions
If you think your product is malfunctioning, read 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 you do not understand a troubleshooting remedy, or
your product needs service, contact Marvel directly at
+1.800.223.3900.
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.
All models incorporate rigid foam insulated cabinets to
provide high thermal efciency 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 oors and paneled walls have a
tendency to reect 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.
