It is normal to see some frost or ice crystals especially on frozen food. This is caused by moisture inside the food itself or inside the freezer. see if one of the following will solve the problem.

Store food properly

Food placed inside the freezer is usually warmer than the appliance’s internal temperature. As the food cools, it is normal to see some condensation turning into frost or ice crystals on it. To avoid this, make sure to store food in sealed, freezer-safe and moisture-proof containers or wraps. 

Avoid opening the door too frequently or keeping it open for long

If the doors of the freezer are opened frequently or if they are not sealed properly, the warmer air from the outside will get into the appliance. This warm air turns to moisture when it comes into contact with the cooler temperatures and forms frost or ice crystals on food.

To avoid this, try not to open the door too much and don’t leave it open for too long. Make sure food or other items are not obstructing the doors from being closed. 

Check for gaps, cracks, or tears on the door seals 

In addition, check the door seals to see if there are any gaps between them and the cabinet. If you find any, adjust the door seal by gently pulling it away from the door using your fingers.

If the doors are not sealing properly, try cleaning the seal with a soft cloth or sponge and warm water. Avoid using abrasive cleaning products as they might damage the seals. If a seal is loose or cracked, it needs to be repaired or completely replaced. If you suspect this to be the case, contact an authorised service agent
