Condensation or moisture forming on the exterior of the cabinet or around the door seals.

Safety first: Unplug the refrigerator before inspecting electrical anti-condensation heaters.

Step-by-step:

• Reduce humidity: Use ventilation or a dehumidifier in very humid rooms.
• Check gasket seal: Inspect for gaps or damage. Clean and reshape as needed.
• Avoid prolonged door openings: Plan what you need before opening the door to minimize warm, moist air entering.
• Inspect heater (if applicable): Some models have a mullion or frame heater. If large amounts of condensation persist, a technician should check heater operation.

Note: Light condensation in very humid conditions can be normal.
