Excessive frost buildup on interior walls, baskets, and food packages.

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

Steps to reduce frost buildup:

• Inspect door gasket: Look for tears, gaps, or hardened sections. Clean the gasket with warm soapy water and dry thoroughly to improve sealing.
• Check door alignment: Ensure the door closes evenly and is not sagging. Adjust hinges if necessary.
• Defrost manually: Remove food to a cooler, unplug the freezer, and leave the door open until all frost melts. Use towels to absorb water.
• Avoid frequent openings: Minimize door openings and avoid leaving the door open for extended periods, especially in humid conditions.
• Replace gasket if needed: If the gasket does not seal even after cleaning and adjustment, install a new Costway freezer door gasket.

Note: Excess frost reduces cooling efficiency and should be addressed promptly.
