Heavy frost buildup on freezer walls, ceiling, and food packages

Safety first: Unplug the freezer before defrosting. Do not use sharp tools to remove ice.

• Inspect door gasket: Look for tears, gaps, or hardened sections. Close the door on a strip of paper at multiple points; if it pulls out easily, the seal is weak. Replace the gasket if necessary.
• Check door alignment: Ensure the door is level and closes squarely against the cabinet. Adjust hinges or leveling legs as needed.
• Defrost the unit: Remove food, unplug the freezer, and leave the door open until all frost melts. Use towels to absorb water.
• Reduce door openings: Minimize how often and how long the door is opened, especially in humid environments.
