Freezer interior surfaces are covered with white powdery frost and ice crystals on food.

Safety: No internal electrical work is needed; unplug only if you plan to defrost.

• Reduce door openings: Plan what you need before opening the door and close it promptly.
• Cool food first: Allow hot or warm food to cool to room temperature before placing it in the freezer, and cover it to reduce moisture.
• Check gasket: Inspect and test the door gasket for leaks. Replace the door gasket if it is damaged.
• Manual defrost: If frost is heavy, unplug the freezer and perform a full manual defrost. Dry the interior thoroughly before restarting.
• Control humidity: If the freezer is in a very humid area, consider moving it or using a dehumidifier.
