Problem Possible Cause Solutions
Refrigerator and
Freezer section are
not cooling.

runs too much.
The refrigerator control is set
to OFF (some models).
Refrigerator is set to Demo
Mode.
Refrigerator is in the defrost
cycle.
Refrigerator was recently
installed.
Refrigerator was recently

Refrigerator is replacing an
older model.
Refrigerator was recently
plugged in or power restored.
The door is opened often or a
large amount of food / hot food
was added.
Doors are not closed
completely.
Refrigerator is installed in a
hot location.
Condenser / back cover is
clogged.
• Turn the control ON. Refer to the Setting the Controls
section for proper temperature settings.
• Demo Mode allows the lights and control display to
work normally while disabling cooling, to save energy
while the refrigerator is on the showroom oor. See the
FAQs section of this manual for instructions on how to
disable Demo Mode.
• During the defrost cycle, the temperature of each
compartment may rise slightly. Wait 30 minutes and
conrm the proper temperature has been restored once
the defrost cycle has completed.
• It may take up to 24 hours for each compartment to
reach the desired temperature.
• If the refrigerator was stored for a long period of time
or moved on its side, it is necessary for the refrigerator
to stand upright for 24 hours before connecting it to
power.
• Modern refrigerators require more operating time but
use less energy due to more efcient technology.
• The refrigerator will take up to 24 hours to cool
completely.
• Adding food and opening the door warms the
refrigerator, requiring the compressor to run longer in
order to cool the refrigerator back down. In order to
conserve energy, try to get everything you need out of
the refrigerator at once, keep food organized so it is
easy to nd, and close the door as soon as the food is
removed. (Refer to the Food Storage Guide.)
• Firmly push the doors shut. If they will not shut all the
way, the "Doors will not close correctly or pop open"
section.
• The compressor will run longer under warm conditions.
At normal room temperatures (70 °F) expect your
compressor to run about 40 % to 80 % of the time.
Under warmer conditions, expect it to run even more
often. The refrigerator should not be operated above
110 °F.
• Use a vacuum cleaner with an attachment to clean the
condenser cover and vents. Do not remove the panel
covering the condenser coil area.

Cooling
Problem Possible Cause Solutions
• When the doors are opened often or for long periods
of time, warm, humid air enters the compartment.
This raises the temperature and moisture level within
the compartment. To lessen the effect, reduce the
frequency and duration of door openings.
• See the "Doors will not close correctly or pop open"
section.
• Humid weather allows additional moisture to enter the
compartments when the doors are opened leading to
condensation or frost. Maintaining a reasonable level of
humidity in the home will help to control the amount of
moisture that can enter the compartments.
• During the defrost cycle, the temperature of each
compartment may rise slightly and condensation may
form on the back wall. Wait 30 minutes and conrm that
the proper temperature has been restored once the
defrost cycle has completed.
• Food stored uncovered or unwrapped, and damp
containers can lead to moisture accumulation within
each compartment. Wipe all containers dry and store
food in sealed packaging to prevent condensation and
frost.
• Rearrange items with high water content away from air
vents.
• If the temperature is too cold, adjust the control one
increment at a time and wait for the temperature to
stabilize. Refer to the Control Panel section for more
information.
• When the refrigerator is operated in temperature
below 41°F (5°C), food can freeze in the refrigerator
compartment. The refrigerator should not be operated
in temperature below 55°F (13°C).
• It may take up to 24 hours for each compartment to
reach the desired temperature.
• Locate air vents by using your hand to sense airow
and move all packages that block vents and restrict
airow. Rearrange items to allow air to ow throughout
the compartment.

Ice & Water

House water supply is not
connected, valve is not turned on
fully, or valve is clogged.
• The icemaker will produce approximately 70-184 cubes
in a 24 hour period.
• Connect the refrigerator to a cold water supply with
adequate pressure and turn the water shutoff valve fully
open. If the problem persists, it may be necessary to
contact a plumber.
• Replacing the water lter is recommended:
• Approximately every six months.

or icemaker recently connected.
Icemaker not turned on.
• When the water lter indicator turns on.
• When the water dispenser output decreases.
• When the ice cubes are smaller than normal.
• The water pressure must be between 20 and 120 psi
on models without a water lter and between 40 and
120 psi on models with a water lter. If the problem
persists, it may be necessary to contact a plumber.
• Reverse osmosis ltration systems can reduce the
water pressure below the minimum amount and result
in icemaker issues. (Refer to the Connecting the Water
Line section.)
• The tubing can kink when the refrigerator is moved
during installation or cleaning resulting in reduced water
ow. Straighten or repair the water supply line and
arrange it to prevent future kinks.
• If the doors of the unit are opened often, ambient
air will warm the refrigerator which will prevent the
unit from maintaining the set temperature. Lowering
the refrigerator temperature can help, as well as not
opening the doors as frequently.
• If the doors are not properly closed, ice production will
be affected. See the "Doors will not close correctly or
pop open" section in Parts & Features Troubleshooting
for more information.
• The recommended temperature for the freezer
compartment for normal ice production is 0°F. If the
freezer temperature is warmer, ice production will be
affected.
• It may take up to 24 hours for each compartment to
reach the desired temperature and for the icemaker to
begin making ice.
• Locate the icemaker ON/OFF and conrm that it is
turned on.

• Foreign substances or frost on the ice-detecting sensor
can interrupt ice production. Make sure that the sensor
area is clean at all times for proper operation.
• Connect the refrigerator to the water supply and turn
the water shutoff valve fully open.
• If your icemaker is equipped with an ice shutoff arm,
make sure that the arm moves freely. If your icemaker
is equipped with the electronic ice shutoff sensor, make
sure that there is a clear path between the two sensors.
• Reverse osmosis ltration systems can reduce the
water pressure below the minimum amount and result
in icemaker issues. (Refer to the Connecting the Water
Line section.)
• A water lter may need to be installed to eliminate taste
and odor problems. NOTE: In some cases, a lter may
not help. It may not be possible to remove all minerals/
odor/taste in all water supplies.
• Ice that has been stored for too long will shrink,
become cloudy, and may develop a stale taste. Throw
away old ice and make a new supply.
• Rewrap the food. Odors may migrate to the ice if food
is not wrapped properly.
• See the Maintenance section for more information.
• Empty and wash the bin (discard old cubes). Make sure
that the bin is completely dry before reinstalling it.
• Empty the ice bin. If your icemaker is equipped with an
ice shutoff arm, make sure that the arm moves freely.
If your icemaker is equipped with the electronic ice
shutoff sensor, make sure that there is a clear path
between the two sensors. Reinstall the ice bin and wait
24 hours to conrm proper operation.

• See Door Alignment in the Refrigeration Installation
section to level refrigerator.
• Clean the gaskets and the surfaces that they touch.
Rub a thin coat of appliance polish or kitchen wax on
the gaskets after cleaning.
• When you open the door, warmer air enters the
refrigerator. As the warm air cools, it can create a
vacuum. If the door is hard to open, wait one minute to
allow the air pressure to equalize, then see if it opens
more easily.
• Refer to the Leveling and Door Alignment section.
• It may be necessary to add shims under the leveling
legs or rollers to complete installation.
• The refrigerator compartment lamp is LED interior
lighting, and service should be performed by a qualied
technician.
• Set the Air Filter to the MAX setting. If the odor does
not go away within 24 hours, the lter may need to be
replaced. See the Replacing the Air Filter section for
replacement instructions.
• Make sure that the refrigerator is not located near a re
