If you are noticing frost buildup in the freezer compartment, there are a few different things to check that might resolve this issue.

Doors Opened Frequently

Every time the door opens, cold air escapes and warm air enters the cabinet. The warm air contains moisture that condenses and freezes in the unit. If the doors are opened often, a small amount accumulating on food, shelves, and rails is normal. This can be removed with a warm, wet cloth. Dry off any surfaces after removing the frost.

Blocked Door

If there is something blocking the door preventing it from closing completely, warm air will be able to enter the unit. This will cause frost buildup in the unit. Rearrange the food items in the freezer so that the item is no longer blocking the door. Remove the frost with a warm, wet cloth.

Doors Closing Properly

Make certain that the door seal is clean and the door is closing properly. Check for cold air escaping from the door by running your hand around the perimeter of the door. If you feel cold air coming out, check to see if the seal is dirty or damaged in that area. Also, check to see if the door opens and closes smoothly and straight.

Temperature Setting

Frost buildup can also occur in the freezer if the temperature is set too low when there is not much food in the unit or if the doors are not open very often. Try raising the temperature in the unit so that it is not as cold. How much will vary depending on the amount of food inside the unit and how often the doors are opened.

Hot Items Added

Warm air contains moisture, which will freeze in the unit. This can happen if hot items have been added to the freezer compartment. When hot foods are placed inside the unit, moisture from these items will condense in the freezer compartment leaving a layer or area of frost. Remove the frost with a warm, wet cloth. Allow food to cool before storing it in the freezer. This will prevent frost from occurring.

Freezer Too Full

If there is too much food in the freezer, this will inhibit proper air circulation which will cause frost formation. Make certain that nothing is blocking the air vents and that there is not too much in the freezer compartment. Try removing some items and rearranging the items.
