BASIC SAFETY PRECAUTIONS
This guide contains many important safety messages. Always read and obey all
safety messages.
w This is the safety alert symbol. It alerts you to safety messages that inform you of hazards that can kill
or hurt you or others or cause damage to the product. All safety messages will be preceded by the safety
alert symbol and the hazard signal word DANGER, WARNING, or CAUTION. These words mean:
wDANGER
wWARNING
wCAUTION
All safety messages will identify the hazard, tell you how to reduce the chance of injury, and tell you
what can happen if the instructions are not followed.
You might be killed or seriously injured if you don’t follow instructions.
You can be killed or seriously injured if you don’t follow instructions.
Indicates an imminently hazardous situation which, if not avoided, may
result in minor or moderate injury, or product damage.
wWARNING
To reduce the risk of fire, electric shock, or
injury to persons when using your product,
basic safety precautions should be followed,
including the following.
Read all instructions before using this appliance.
• NEVER unplug your refrigerator by pulling on the
power cord. Always grip the plug firmly and pull it
straight out from the outlet.
• Repair or replace immediately all electric service
cords that have become frayed or otherwise
damaged. Do not use a cord that shows cracks or
abrasion damage along its length or at either the
plug or connector end.
• When moving your refrigerator away from the wall,
be careful not to roll over or damage the power cord.
• DO NOT store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any other
appliance.
• Do NOT allow children to climb, stand, sit or hang
on doors, drawers or shelves of the refrigerator.
They could damage the refrigerator and seriously
injure themselves.
• Keep fingers out of pinch point areas; clearances
between the doors and cabinet are necessarily
small. Be careful closing doors when children are
in the area.
• Unplug your refrigerator before cleaning or making
any repairs.
NOTE: Service should be performed by a qualified
technician.
• Before replacing a burned-out light bulb, unplug the
refrigerator or turn off power at the circuit breaker
or fuse box in order to avoid contact with a live wire
filament. (A burned-out light bulb may break when
being replaced.)
NOTE: Some models have LED interior lighting and
service should be performed by a qualified
technician.
NOTE: Setting either or both controls to the OFF
position does not remove power to the light circuit.
• When you are finished, reconnect the refrigerator to
the electrical source and reset the control
(Thermostat Refrigerator Control, or Freezer
Control, or Freezer Control, depending on the
model) to the desired setting.
• This refrigerator must be properly installed in
accordance with the Installer Instructions that
were taped to the front of the refrigerator.
• After your refrigerator is in operation, do not touch
the cold surfaces in the freezer compartment when
hands are damp or wet. Skin may adhere to the
extremely cold surfaces.
• In refrigerators with automatic icemakers, avoid
contact with the moving parts of the ejector
mechanism or with the heating element that
releases the cubes. DO NOT place fingers or hands
on the automatic icemaking mechanism while the
refrigerator is plugged in.
• Do not modify or extend the power cord length.
It will cause electric shock or fire.

BASIC SAFETY PRECAUTIONS
(CONT.)
• DO NOT refreeze frozen foods which have
thawed completely. The United States
Department of Agriculture in Home and Garden
Bulletin No. 69 says:
…You may safely refreeze frozen foods that have
thawed if they still contain ice crystals or if they are
still cold—below 40°F (4°C).
…Thawed ground meats, poultry, or fish that have
any off-odor or off-color should not be refrozen
and should not be eaten. Thawed ice cream
should be discarded. If the odor or color of any
food is poor or questionable, dispose of it. The
food may be dangerous to eat.
wDANGER
Risk of Child Entrapment
Discarded or abandoned refrigerators are
dangerous, even if they will sit for just a few
days. If you are disposing of your old refrigerator,
please follow the instructions below to help prevent
accidents.
Before you throw away your old refrigerator or
freezer:
• Take off the doors.
• Leave the shelves in place so that children may
not easily climb inside.
Even partial thawing and refreezing reduces the
quality of foods, particularly fruits, vegetables,
and prepared foods. The eating quality of red
meats is affected less than that of many other
foods. Use refrozen foods as soon as possible to
save as much of their quality as you can.
CFC DISPOSAL
Your old refrigerator may have a cooling system
that used CFCs (chlorofluorocarbons). CFCs are
believed to harm stratospheric ozone.
If you are throwing away your old refrigerator,
make sure the CFC refrigerant is removed for
proper disposal by a qualified servicer. If you
intentionally release this CFC refrigerant, you can
be subject to fines and imprisonment under
provisions of environmental legislation.

HOW TO CONNECT ELECTRICITY
IMPORTANT: Please read carefully.
wWARNING
Electrical Shock Hazard
For personal safety, this appliance must be
properly grounded. Have the wall outlet and
the circuit checked by a qualified electrician to
make sure the outlet is properly grounded.
RECOMMENDED GROUNDING METHOD
The refrigerator should always be plugged into
its own individual properly grounded electrical
outlet rated for 120 volts, 60 Hz, AC only, and
fused at 20 amperes. This provides the
best performance and also prevents overloading
house wiring circuits which could cause a fire
hazard from overheated wires. It is
recommended that a separate circuit serving
only this appliance be provided.
Use a receptacle which cannot be turned off with
a switch or pull chain. Do not use an extension
cord. Where a standard two-prong wall outlet is
encountered, it is your personal responsibility
and obligation to have it replaced with a properly
grounded three-prong wall outlet.
Do not, under any circumstances, cut or
remove the third (ground) prong from the
power cord.
Do not use an adapter plug.
NOTE: Some models have LED interior lighting and
service should be performed by a qualified technician.
When you are finished, reconnect the refrigerator to
the electrical source and reset the control
(Thermostat, Refrigerator Control, or Freezer Control,
depending on the model) to the desired setting.
USE OF EXTENSION CORDS
Because of potential safety hazards under
certain conditions, we strongly recommend
against the use of an extension cord.
However, if you still elect to use an extension
cord, it is absolutely necessary that it be a UL-listed
(USA), 3-wire grounding-type appliance
extension cord having a grounding-type plug
and outlet and that the electrical rating of the
cord be 20 amperes (minimum) and 120 volts.
Use of an extension cord will increase the
clearance needed for the back of the
refrigerator.
