LG Refrigerator - Troubleshooting Frost or Moisture Buildup In Your LG Refrigerator

  • Troubleshooting

At a Glance

When moisture in the air meets the air inside the refrigerator, it may form frost or icicles on the wall of the refrigerator or the surface of food.
This is a natural phenomenon caused by the proper functioning of the refrigerator and not a malfunction.
To remove the frost, wipe it off with a clean dishcloth on a sunny day and once again wipe off moisture with a dry towel.

Frost may build up if:

  • You put food in the refrigerator when it was hot.
  • You stored watery foods in the refrigerator without putting them in an airtight container.
  • The door is not closed properly.
  • You restarted the power of the refrigerator.
  • Defrosted water leaks from the front.
  • Frost is formed in the refrigerator.
  • Dew forms in the refrigerator.
Removing frost inside the refrigerator with a dry cloth, not a knife and an awl
Warning!

Be careful not to use a sharp knife or awl to remove frost, as that may damage the refrigerator.

Try this

Did you put food in the refrigerator before allowing it to cool?

➔ Put in the food after it cools down to a reasonable temperature.

Vapor is created as hot food cools down and forms frost when it meets the cold air inside the refrigerator.

Don't put hot food in the refrigerator right away

Did you store watery foods in the refrigerator without first putting them in an airtight container?

➔ Keep such food in airtight containers or a plastic bags.

Moisture coming out of the food may create frost when it meets the cold air inside the refrigerator.

Wrong example: food stored unsealed. Correct example: food stored in an airtight container.

Is the door not closed tightly, and air outside being allowed to get into the refrigerator?

➔ Check the following and close the door of your refrigerator tightly.

If the door of the refrigerator is not tightly closed, moisture in the outside air may create icicles or frost in the refrigerator when it meets the cold air.
If the drawers or shelves haven’t been reassembled properly after cleaning the refrigerator, remove and reinsert them correctly.
If you have placed too much food in the compartment, take some of the food out.
If the rubber seal becomes contaminated and becomes sticky, clean it and do so frequently.

The refrigerator door is open and the outside air is flowing in

Has there been a long power failure? Did you power the refrigerator off and on?

➔ As the air that became warmer during power off cools down again, moisture inside the air may form frost due to the temperature differences.
This may disappear naturally after 1 to 2 weeks of use.

During the power cut to the refrigerator, the temperature of the air inside the refrigerator rises.
Then, turning on the power again will cool down the air, and any moisture in the air may become frost.
When the refrigerator is filled with cold air, and its operation is stabilized with any moisture inside starting to vaporize, the frost will naturally disappear.

The frost inside the refrigerator disappeared naturally
