Rubber door gasket is moldy, sticky, or deteriorating.

Safety: No electrical work required.

• Clean gasket: Wipe with warm soapy water and a soft cloth. For mold, use a mild solution of vinegar or a refrigerator-safe disinfectant.
• Inspect for cracks: If the gasket is torn, hardened, or no longer seals, it must be replaced.
• Replace gasket: Warm the new door gasket to make it flexible, then fit it into the door channel, pressing firmly all around. Check for uniform sealing.
