Precautionary measures
• Verify the refrigerator is plugged in securely to a 120V grounded outlet and the outlet has power by testing with another appliance
• Ensure both the refrigerator and freezer doors are completely closed and the door seals are not damaged or cracked
• Check that temperature settings are configured appropriately (typically 37-40°F for fresh food, 0°F for freezer) and adjust if needed
• If the error appeared after a power outage, unplug the refrigerator for 60 seconds, then plug it back in to allow the system to reset
• Verify the appliance is not located in direct sunlight or near heat sources and is positioned on a level, stable surface
• Confirm air vents on the back and inside the refrigerator are not blocked by food items or debris
• Check that nothing is obstructing the door closure and the appliance is not tilted
• If the error persists after these checks, contact a professional appliance repair technician who can diagnose and repair sensor or control board issues
