Cabinet interior shows signs of rust or corrosion, especially near seams or screws.

Safety first: Unplug the unit before cleaning or treating rust.

Steps to mitigate:

• 1. Address moisture source: Clear the evaporator drain and ensure no standing water remains.
• 2. Clean affected areas: Remove loose rust with a non-metallic scrub pad and clean with mild detergent.
• 3. Treat and seal: Apply an appliance-safe touch-up paint or sealant to protect exposed metal.
• 4. Control humidity: Ensure the door gasket seals properly and avoid leaving the door open for long periods.
