Frost Buildup - FREEZER ONLY


If the unit is too cold, ensure that the temperature for BOTH the refrigerator and freezer compartments are set properly. Most models will default to for the freezer and 37° for the refrigerator.

For information about frost issues on the entire product, visit our Frost Buildup - Entire Unit article.

If frost is built up on one side of the freezer more than the other this indicates that the freezer drawer is not sealing properly;

Re-arrange food items to ensure that nothing is blocking the door from shutting completely and monitor the unit for 4-6 hours.

Perform the steps below to resolve the frost issue:

  1. Check door sealing.

    When the door is not properly sealed, cold air will escape from the door seal which will cause frosting. Ensure that NO items are blocking the door from closing.

  2. Check door gasket.

    If the door gasket is dirty or compressed, clean it by using warm water or mild detergent and pull out any compressed part.

    check the gasket
  3. Hot food in the unit.

    Adding hot food to the refrigerator compartment will temporarily dissipate warm heat throughout the unit. The unit will require some time to cool down the hot food and regulate its internal temperature.

  4. Check air vents.

    Be sure to check the air vents in both compartments for frost buildup.

    Frost buildup on the return air vents will restrict cold air from entering different sections of the refrigerator and reduce the cooling efficiency of the entire unit.
