Condensation or moisture on the inside of the glass door

Safety: No internal electrical work is required for basic checks; unplug only if removing panels.

• Inspect gasket: Check the door gasket all around for cracks, warping, or gaps. Replace the CELLA door gasket if it does not seal tightly.
• Check door alignment: Ensure the door is level and closes evenly. Adjust hinges if the door sags.
• Control humidity: In very humid environments, consider using a room dehumidifier and minimizing door openings.
• Door heater (if present): Some models have a low-wattage heater around the door frame. If condensation is severe and persistent, a technician may need to test and replace the door frame heater.
