What is this "fog" when I open the doors?

Fog appearing when I open the refrigerator or freezer door

Refrigerators and freezers maintain colder air temperatures inside. When the door is opened, warm air enters and mixes with the cold air inside. The result is condensation, usually in the form of fog. During periods of high humidity and warmer temperatures, the room air entering the refrigerator or freezer when the door is opened may even condense on the inside walls and appear as water droplets. To help reduce this condition, try the following:

  • Arrange shelving and food items so air circulates well inside the food compartment. Don't overload or underload the appliance. We recommend keeping the freezer and refrigerator sections 1/2 to 3/4 full.
  • Set the temperature controls as recommended in your Use and Care Guide. Control adjustment may be needed as the room temperature changes from season to season.
  • Avoid frequent or unnecessary door openings.
  • Properly seal liquids and high-moisture foods stored in the refrigerator section. Make sure hot foods are cool before putting them in the refrigerator or freezer.
  • If your refrigerator or freezer is in the kitchen, cover pots and pans when cooking to reduce moisture in the kitchen.
  • Make sure the door gasket is sealing properly. A good seal keeps warm moist air out of the food compartment. Refer to your Use and Care Guide for proper door gasket maintenance.
  • Reduce humidity in your home by using an air conditioner or dehumidifier during warm weather.
