Condensation or fogging on the inside of the glass door.

Safety: No internal electrical work is required for basic checks.

Steps:

• Check door seal: Inspect the gasket for gaps and ensure the door closes firmly. Perform the paper test around the perimeter.
• Reduce door openings: Limit how often and how long the door is open, especially in humid climates.
• Room humidity: Use a dehumidifier in very damp rooms to reduce moisture entering the cooler.
• Door heater (if present): Some Magic Chef models have a low-wattage heater around the door frame. If the outer frame feels cold and condensation is heavy, the heater circuit may have failed, requiring control board or heater wire replacement by a technician.

Note: Light condensation can be normal in humid conditions; heavy or persistent fogging usually indicates a sealing issue.
