Heavy frost buildup on walls, shelves, and food.

Safety first: Unplug the freezer before defrosting.

• Full manual defrost: Remove all food, unplug the unit, and leave the door open until all frost has melted. Use towels to absorb water.
• Inspect gasket: Check for cracks, gaps, or hardened sections. Replace the gasket if it does not seal all around.
• Check door alignment: Ensure hinges are tight and the door is not sagging. Adjust if necessary so the door closes squarely.
• Review usage: Avoid leaving the door open for long periods and allow hot food to cool before placing it in the freezer.
• Defrost system check: If frost quickly returns, follow defrost system troubleshooting steps (heater, sensor, control).
