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

Safety first: No internal electrical work is usually required.

Step-by-step checks:

• 1. Reduce humidity: Avoid placing the refrigerator near open windows, cookers, or humidifiers.
• 2. Check door seals: Ensure gaskets are sealing properly; repair or replace if necessary.
• 3. Avoid frequent opening: Limit door openings during very humid weather.

When to call a technician: If condensation is severe and persistent, the mullion heater circuit or cabinet insulation may need professional evaluation.
