1. Make sure the refrigerator temperature is set correctly. See Refrigerator and Freezer Temperature Settings for details.
   • Factory settings on electronic control panels are 38°F (3°C) in a refrigerator and 0°F (-18°C) in a freezer. These are ideal food storage temperatures.
2. Clean the Condenser if it has not been done in the past 6 to 12 months.
3. Verify the door is shut tightly. Remove anything that is blocking the door from shutting completely.
4. Verify the door gasket is in good shape with no rips or tears. If the gasket is damaged, contact Factory Certified Service to schedule an appointment for repair.
