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-freel
refrigerators have a defrost timer
that
will
generate
a clicking
sound when it cycles the unit
into and out of defrost cyc e.
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
norma sounds necessary for making ice.
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.
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.
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 isstill 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 coo ed.
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.
WATER VALVE (if equipped): A buzzing I
sound may be detected in the back
ofl
the unit when the ice dispenser calls for I
the water valve to open to fill the ice I
maker tray. Following the ejection of the I
ice, there may be some water dripping
sounds when the trays are being fied.
CABINET
LEVELING:
An unlevel
cabinet may cause rattling or vibrating
noises. This can be fixed by adjusting
the wheels or levelers properly.
