FAQs

Frequently Asked Questions

Q: What are the best temperature settings for my refrigerator and freezer?

A: The default setting for the refrigerator is 37° Fahrenheit (3° Celsius). The default setting for the

freezer is 0° Fahrenheit (-18° Celsius). Adjust these settings as necessary to keep food at desired
temperatures. Milk should be cold when stored on the inner shelf of the refrigerator. Ice cream
should be firm and ice cubes should not melt in the freezer. To switch the display from Fahrenheit to
Celsius, press and hold the Freezer and Refrigerator buttons until you hear a beep and the settings
in the display change.

Q: How do I set the refrigerator and freezer temperatures?

A: Continually press the Refrigerator or Freezer button on the control panel until the desired

temperature appears. The numbers will cycle from highest to lowest and then return to the highest
again with continuous pressing.

Q: Why do I hear a buzzing noise from my refrigerator periodically?

A: This may happen if you do not have a water source attached to your refrigerator and the icemaker is

turned on. If you do not have a water source attached to the back of the refrigerator you should turn
the icemaker off.

Q: Why does the icemaker tray look crooked?

A: This is a normal part of the icemaker cycle. The icemaker tray may appear level or with a slight tilt.

The change in position is to assist in the freezing process.

Q: My refrigerator is powered on and the controls are working, but it’s not cooling and the display

shows “OFF” (see below). What is wrong?

A: The refrigerator is in Display Mode. The Display Mode disables all cooling in the refrigerator and

freezer sections to conserve energy while on display in a retail store. When activated, OFF is displayed
on the control panel and the display remains on for 20 seconds. With either refrigerator door opened,
press the Ice Plus button 3 times consecutively while pressing the Refrigerator button. The control
panel beeps and the temperature settings display to confirm that Display Mode is deactivated. Use
the same procedure to activate Display Mode.

Cooling

Problem Possible Cause & Solution

Refrigerator and
Freezer section are
not cooling.

Cooling system runs
too much.

The refrigerator control is set to OFF (some models).

• Turn the control ON. Refer to the Setting the Controls section for proper temperature
settings.

Refrigerator is set to Demo Mode.

• Demo Mode allows the lights and control display to work normally while disabling cooling,
to save energy while the refrigerator is on the showroom floor. See the FAQs section of
this manual for instructions on how to disable Demo Mode.

Refrigerator is in the defrost cycle.

• During the defrost cycle, the temperature of each compartment may rise slightly. Wait 30
minutes and confirm the proper temperature has been restored once the defrost cycle has
completed.

Refrigerator was recently installed.

• It may take up to 24 hours for each compartment to reach the desired temperature.

Refrigerator was recently relocated.

• 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.

Refrigerator is replacing an older model.

• Modern refrigerators require more operating time but use less energy due to more
efficient technology.

Refrigerator was recently plugged in or power restored.

• The refrigerator will take up to 24 hours to cool completely.

The door is opened often or a large amount of food / hot food was added.

• 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 find, and close the door as soon as the food is removed. (Refer to the Food Storage
Guide.)

Doors are not closed completely.

• Firmly push the doors shut. If they will not shut all the way, the "Doors will not close
correctly or pop open" section in Troubleshooting.

Refrigerator is installed in a hot location.

• The compressor will run longer under warm conditions. At normal room temperatures (70
°F or 21 °C) 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 (43 °C).

Condenser / back cover is clogged.

• Use a vacuum cleaner with an attachment to clean the condenser cover and vents. Do not
remove the panel covering the condenser coil area.

Problem Possible Cause & Solution

Interior moisture
buildup.

Food is freezing in
the refrigerator
compartment.

Refrigerator or
Freezer section is too
cold.

Frost or ice crystals
form on frozen food
(inside of sealed
package).

Frost or ice crystals
form on frozen food
(outside of package).

Doors are opened often or for long periods of time.

• 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.

Doors are not closed correctly.

• See the "Doors will not close correctly or pop open" section.

Weather is humid.

• 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.

Defrost cycle recently completed.

• During the defrost cycle, the temperature of each compartment may rise slightly and
condensation may form on the back wall. Wait 30 minutes and confirm that the proper
temperature has been restored once the defrost cycle has completed.

Food is not packaged correctly.

• 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.

Food with high water content was placed near an air vent.

• Rearrange items with high water content away from air vents.

Refrigerator temperature control is set incorrectly.

• 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.

Refrigerator is installed in a cold location.

• 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).

Incorrect temperature control settings.

• 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 for more information.

Condensation from food with a high water content has frozen inside of the food
package.

• This is normal for food items with a high water content.

Food has been left in the freezer for a long period of time.

• Do not store food items with high water content in the freezer for a long period of time.

Door is opened frequently or for long periods of time.

• 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.
Increased moisture will lead to frost and condensation. To lessen the effect, reduce the
frequency and duration of door openings.

Door is not closing properly.

• Refer to the "Doors will not close correctly or pop open" section in the Troubleshooting.

Problem Possible Cause & Solution

Refrigerator or
Freezer section is too
warm.

Refrigerator was recently installed.

• It may take up to 24 hours for each compartment to reach the desired temperature.

The air vents are blocked. Cold air circulates from the freezer to the fresh food section
and back again through air vents in the wall dividing the two sections.

• Locate air vents by using your hand to sense airflow and move all packages that block
vents and restrict airflow. Rearrange items to allow air to flow throughout the
compartment.

Doors are opened often or for long periods of time.

• 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.

Unit is installed in a hot location.

• The refrigerator should not be operated in temperatures above 110 °F (43 °C).

A large amount of food or hot food was added to either compartment.

• Adding food warms the compartment requiring the cooling system to run. Allowing hot
food to cool to room temperature before putting it in the refrigerator will reduce this
effect.

Doors are not closed correctly.

• See the "Doors will not close correctly or pop open" section in the Troubleshooting.

Temperature control is not set correctly.

• If the temperature is too warm, adjust the control one increment at a time and wait for the
temperature to stabilize.

Defrost cycle has recently completed.

• During the defrost cycle, the temperature of each compartment may rise slightly and
condensation may form on the back wall. Wait 30 minutes and confirm the proper
temperature has been restored once the defrost cycle has completed.
