The F2 error in Carrier AC indicates an issue with the outdoor air temperature sensor, meaning that the sensor responsible for measuring the temperature of the air outside the unit is malfunctioning or providing incorrect readings. This sensor plays a key role in regulating the operation of the air conditioner by ensuring the system adjusts to external temperature changes. When the F2 error is triggered, it suggests that the outdoor air temperature sensor is either faulty, disconnected, or giving abnormal temperature readings. Possible causes include sensor failure, damaged wiring, or issues with the sensor’s connection to the control board. Since the sensor helps the system adjust its operation according to the outdoor conditions, a malfunction can lead to inefficiencies in cooling or improper functioning of the unit. To protect the system, the F2 error will cause the air conditioner to stop or operate erratically until the sensor issue is resolved. Once the faulty sensor is replaced or the wiring is repaired, the system will reset, and the air conditioner will return to normal operation. Regular maintenance, including checking the condition of the outdoor air temperature sensor and ensuring proper wiring and connections, can help prevent the F2 error and ensure the Carrier AC functions efficiently in varying outdoor conditions.
