Ice forming on the inside walls or ceiling of the refrigerator compartment.

Checks:

• Inspect the door gasket for tears, gaps, or hardened sections. Clean with warm soapy water and dry.
• Close the door on a sheet of paper at various points around the seal; if the paper pulls out easily, the seal may be weak or the door misaligned.
• Adjust door hinges if the door is sagging or not square with the cabinet.

Seal replacement:

• If the gasket is damaged, pull it out of the retaining groove and press in a new gasket, ensuring it seats fully around the perimeter.
• Warm the new gasket gently with a hair dryer (on low) to help it conform and seal.
