Condensation or water droplets forming on the exterior of the cabinet or around the door seal.

Safety first: No internal electrical work is usually required.

Steps:

• Reduce door openings: Minimize how often and how long the door is open.
• Check gasket: Clean the door gasket and cabinet mating surface. Replace the gasket if it is torn or deformed.
• Ambient humidity: Use a dehumidifier in very humid rooms or improve ventilation.
• Anti-condensation heater: Some models have a heater around the door frame. If condensation is severe and persistent, a technician can test and replace this heater if faulty.
