Precautionary measures
• Verify the refrigerator is plugged in securely and the power outlet is functioning by testing with another appliance
• Ensure both the refrigerator and freezer doors are fully closed and sealing properly
• Check that the temperature control settings are set to appropriate levels (typically 35-38°F for fridge, 0°F for freezer)
• Unplug the refrigerator for 60 seconds, then plug it back in to allow the control board to reset
• Alternatively, turn off the circuit breaker serving the refrigerator for 60 seconds, then turn it back on
• Confirm the refrigerator is level by checking that it doesn't tilt forward or to the sides
• Inspect the back of the refrigerator to ensure vents and air passages are not blocked by dust or debris
• Allow 4-6 hours after power restoration for the appliance to stabilize to proper operating temperature
• If the error code persists after these checks, contact a professional appliance repair technician or appliance repair support service to diagnose the control board or sensor issue
