Troubleshooting
Normal Operating Sounds
Improvements in refrigeration design may produce sounds in your new refrigerator that are different or were not
present in an older model. These improvements were made to create a refrigerator that is better at preserving food,
is more energy efficient, and is quieter overall. Because new units run quieter, sounds may be detected that were
present in older units, but were masked by higher sound levels. Many of these sounds are normal. Please note that
the surfaces adjacent to a refrigerator, such as hard walls, floors and cabinetry may make these sounds seem even
louder. The following are some of the normal sounds that may be noticed in a new refrigerator.
DEFROST TIMER: Frost-free
refrigerators have a defrost timer
that will generate a clicking
sound when it cycles the unit
into and out of defrost cycle.
ICE MAKER: (if equipped) The ice maker
will occasionally generate a rattling sound
when the ice cubes are ready to drop down
into the ice bin. Also, the motor that ejects
the ice from its tray prior to dropping the
ice may also be detectable. These are
normal sounds necessary for making ice.
FREEZER COMPARTMENT
CONTRACTION AND EXPAN-
SION:
A popping sound may
occur in the freezer when the
unit starts up due to contraction
or expansion of the materials in
the freezer area.
DEFROST HEATER: During
the automatic defrost cycle, a
sizzling sound may be heard
as water droplets come into
contact with the defrost
heater. This is a normal
sound heard during defrost.
REFRIGERANT FLOW: The flow of the
refrigerant in your refrigerator may cause a
gurgling or rattling sound when the unit is
running or just after the unit cycles off. The
refrigerant is still flowing in the tubing.
AIRFLOW SOUNDS: Both the freezer
evaporator fan and the condenser fan at the
bottom of the cabinet will create airflow
sounds. The evaporator fan is circulating the
cold air throughout the refrigerator and freezer
compartments. The condenser fan is removing
the heat generated when the unit is cooled.
WATER VALVE (if equipped): A buzzing
sound may be detected in the back of
the unit when the ice dispenser calls for
the water valve to open to fill the ice
maker tray. Following the ejection of the
ice, there may be some water dripping
sounds when the trays are being filled.
CABINET LEVELING: An unlevel
cabinet may cause rattling or vibrating
noises. This can be fixed by adjusting
the wheels or levelers properly.
COMPRESSOR: In order for a new
refrigerator to run more efficiently,
the refrigeration system may run
longer to keep food at the desired
temperatures for freshness. That
new, high efficiency compressor may
run longer and generate sounds such
as a higher pitched hum or pulsation.
