Precautionary measures
• Verify the refrigerator is plugged into a working 120V outlet and the outlet has power by testing with another appliance
• Ensure both the refrigerator and freezer doors are fully closed and sealing properly without gaps
• Check that temperature control settings are set to normal cooling positions (not off or minimum)
• Unplug the refrigerator from the electrical outlet for 60 seconds, then plug it back in to reset the control system
• Alternatively, turn off the circuit breaker supplying power to the refrigerator for 60 seconds, then restore power
• Verify the refrigerator is sitting level on the floor using a spirit level; adjust the front leveling feet if necessary
• Inspect air vents inside the refrigerator and freezer compartments for frost, ice, or debris blockages and clear if needed
• Wait 24 hours after power restoration to allow the appliance to stabilize before assessing if the error clears
• If the error persists after these checks, contact a professional appliance repair technician to diagnose sensor and control board issues
