BUILDUP
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. Refer to Multi-Flow on page 20 for the location of air vents.
The doors are opened often.When the door is opened, warm humid air is allowed into the refrigerator. The more the door is opened, the faster the humidity builds up, and the more warm air the refrigerator must cool. In order to keep the refrigerator cool, 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.
The control is not set correctly for the surrounding conditions.Refer to the Setting the Controls section on page 20. Wait 24 hours for temperatures to stabilize or even out. If the temperature is too cold or too warm, move the dial one number at a time.
A large amount of food has just been added to the refrigerator or freezer.Adding food warms the refrigerator. It can take a few hours for the refrigerator to return to normal temperature.
The food is not packaged correctly.Wrap food tightly and wipe off damp containers prior to storing in the refrigerator to avoid moisture accumulation. If necessary, repackage food according to the guidelines in the Food Storage Guide section on page 25.
The doors are not closing completelySee Doors will not close completely on page 40.
The weather is humid.In humid weather, air carries moisture into refrigerator when doors are opened.
