Precautionary measures
• Verify the refrigerator is plugged firmly into a grounded 120V outlet
• Ensure both the refrigerator and freezer doors close completely and latch properly
• Check that the temperature control settings are adjusted to normal operating levels (typically 35-38°F for refrigerator, 0°F for freezer)
• Unplug the refrigerator for 60 seconds, then plug it back in to reset the control board
• Allow 30 minutes for the refrigerator to stabilize and resume normal operation after power reset
• Verify that air vents inside both compartments are not blocked by food items or ice buildup
• Confirm the refrigerator is level using a spirit level; adjust leveling feet if necessary
• If the error persists after these checks, contact a professional appliance repair technician who can safely diagnose sensor and control board issues
