Condensation or moisture on the inside of the glass door.

Safety: No internal electrical work is required for basic checks.

• Check gasket: Inspect the door gasket for gaps, tears, or hardened sections. Replace if damaged.
• Ensure full closure: Verify that shelves or bottles are not preventing the door from closing completely.
• Control humidity: Use a dehumidifier in very humid rooms to reduce condensation.
• Door heater (if present): Some models have a low-wattage heater around the door frame. If condensation is severe and persistent, have a technician test and replace the door frame heater if equipped.
