Precautionary measures
• Verify the refrigerator is plugged firmly into a working 120V outlet and check that the outlet has power
• Ensure both the refrigerator and freezer doors close completely and seal properly
• Confirm temperature control settings are not set to the coldest or warmest positions
• Allow the refrigerator 4-6 hours to stabilize after a power interruption or first installation
• Check that air vents inside the refrigerator and freezer compartments are not blocked by food or ice buildup
• Verify the refrigerator is level by checking with a bubble level; adjust the front legs if needed for proper drainage
• Perform a complete power reset by unplugging the refrigerator for 60 seconds, then plugging it back in (alternatively, turn off the circuit breaker for 60 seconds)
• Check the back of the refrigerator to ensure it has adequate clearance from walls and is not overheated
• If the error code persists after these checks, contact a professional appliance repair technician who can test the temperature sensors and control board with specialized diagnostic equipment
