Precautionary measures
• Verify the refrigerator is plugged into a properly grounded 120V outlet and the outlet has power by testing with another appliance
• Check that both the refrigerator and freezer doors close completely and seal properly without gaps
• Ensure the appliance is level by using a spirit level on both front-to-back and side-to-side planes; adjust the leveling feet if needed
• Confirm temperature settings are appropriate (refrigerator 37-40°F, freezer 0°F or below)
• Inspect air vents on the back wall and sides of both compartments to ensure they are not blocked by food items or debris
• Allow the refrigerator 24 hours to stabilize if power was recently restored after an outage or disconnection
• Perform a hard reset by unplugging the refrigerator from the wall outlet for 60 seconds, then plugging it back in, or by switching the circuit breaker to OFF for 60 seconds then back to ON
• Wait 10 minutes after reset and observe if the error code clears and normal cooling operation resumes
• If the fault code persists after these checks, contact a professional appliance repair technician or appliance repair support service to diagnose and repair the control board or sensor components
