Verify the temperature settings are correctly set. Make sure to avoid blocking airflow vents within the product with contains or stored food items as this may reduce cool airflow from being distributed evenly. Putting warm/hot food inside the fridge will also effect the temperature of the refrigerator. If the issue persists please be with your product and contact Hisense Customer Support on 800 447 367.
