Glass door fogs up with condensation on the inside or outside.

Safety: Condensation itself is not dangerous, but water can drip onto floors. Unplug the unit if removing door components.

Steps:

• 1. Reduce humidity: Use a dehumidifier in the room if humidity is high. Avoid placing the cooler near sources of steam.
• 2. Limit door openings: Each opening introduces moist air that can condense on the glass.
• 3. Check door gasket: Ensure a tight seal all around. Replace the gasket if leaking.
• 4. Door heater (if present): Some models have a low-wattage heater around the door frame. If the frame feels cold and condensation is heavy, the heater circuit may have failed and may require control board or heater replacement by a technician.
