Condensation or water droplets forming on the inside of the glass door.

Safety: No internal electrical work is usually required; unplug only if removing trims.

• Check gasket seal: Close the door on a thin sheet of paper at several points. If the paper pulls out easily, the gasket may need adjustment or replacement.
• Reduce humidity: Use a dehumidifier in very humid rooms and avoid placing the cooler near open windows or dishwashers.
• Limit door openings: Minimize how often and how long the door is opened.
• Heated glass models: If equipped with a door heater and condensation is heavy, have a technician test the door heater circuit and replace the door assembly if failed.
