Excessive frost buildup on food packages and interior walls, but temperature is otherwise acceptable.

Safety first: Avoid using sharp tools to remove frost; they can puncture the liner or evaporator.

Reduce moisture load:

• Allow hot or warm food to cool to room temperature before placing in the freezer.
• Limit door opening time and ensure the door is fully closed each time.

Check gasket and door closure:

• Inspect the gasket for gaps and perform the paper test around the perimeter.
• Adjust hinges or replace the gasket if sealing is poor.

Defrost and reset:

• Turn off and unplug the freezer.
• Allow all frost to melt completely; wipe out water.
• Restart and monitor frost buildup over the next week.

Note: Some light frost is normal, but heavy, rapid buildup indicates ongoing air leakage that must be corrected.
