Visible rust or corrosion on internal metal parts and around the door frame.

Safety first: Unplug the unit before performing any rust treatment or painting.

• Step 1 – Address moisture sources: Clear the condensate drain, ensure the door gasket seals properly, and reduce door openings.
• Step 2 – Clean corrosion: Lightly sand affected areas and wipe away debris. Use a rust converter or primer suitable for appliance use.
• Step 3 – Touch-up paint: Apply appliance-grade touch-up paint to protect exposed metal.
• Step 4 – Control environment: Use a dehumidifier in very humid rooms to reduce future condensation.
