PO WER INT ERRUPTIONS
In the event of a power interruption, unplug your
refrigerator from the power source. Avoid opening
the doors until after power has been restored.
Your refrigerator will maintain a cold temperature
for longer if door opening is avoided or kept to a
minimum.
Once power has been restored, plug your
refrigerator back into the power source and
inspect food in the refrigerator for spoilage
or thawing. Cleaning your refrigerator after a
prolonged power outage is strongly recommended
to avoid odors and potential health hazards due to
thawing.
NORMAL OP ERAT ING SOUNDS
WHIRRING
There are multiple high-speed fans inside
your refrigerator which help it to maintain the
temperature you have selected. Whirring is
common when the refrigerator is rst plugged in,
when the doors have been opened often or for an
extended period of time and when a large amount
of food has been added.
HUMMING
This is a common noise that comes from
the compressor and is a part of making your
refrigerator run e ciently.
WHOOSHING
It is possible that you may hear a whooshing
noise when closing the doors. This is no cause
for concern. It is simply the pressure in the
refrigerator equalizing.
VACATIONS
For long vacations or absences, unplug your
refrigerator and remove all food from it. Turn
the temperature control knob in the refrigerator
section to the OFF position and clean the
refrigerator, including the gaskets, according to
the Proper Care and Maintenance section. Leave
the doors propped open to allow air to circulate
inside the refrigerator.
MOV ING
Before moving your refrigerator, empty the
food from it and use adhesive tape to secure all
loose items such as shelves, door bins and racks,
crispers and pans, etc. and unplug it. Always move
the refrigerator in an upright position in order to
avoid damaging the sealed refrigerant system.
OTHER NOISES

refrigerator at any given time. Additional noises
you may hear, and possible causes include:

refrigerant through the cooling coils.
• Sizzling or popping sounds can be frost melting
and falling onto the defrost heater during the
defrost cycle.
• Clicking or chirping may be heard as the
compressor attempts to re-start.
• Cracking or popping noises may be from the
expansion and contraction of cooling coils during
and after the defrost cycle.
• Also, when your refrigerator is rst plugged
in, the foam insulation in the walls will cool and
contract, which can result in cracking or popping
noises.
