Frost or ice buildup on food packages and interior walls despite normal door use.

Safety first: Unplug the freezer before performing a manual defrost.

Steps:

• Manual defrost: Remove food and allow all frost to melt with doors open. Use towels to absorb water.
• Inspect gasket and door use: Check the door gasket and ensure the door is not being left open or opened excessively.
• Check defrost system: On frost-free Insignia freezers, verify that the defrost heater and thermostat are functioning as described in defrost-related entries.
• Reduce humidity: Avoid placing warm, uncovered food inside and minimize door openings in humid conditions.
