The F8 error in Carrier AC indicates an issue with the outdoor compressor suction temperature sensor, meaning the sensor is not functioning correctly or is providing inaccurate readings. The suction temperature sensor plays a critical role in monitoring the temperature of the refrigerant entering the compressor, helping the system maintain efficient operation. When the F8 error occurs, it means that the suction temperature sensor has detected an abnormal reading or has failed. This could be caused by a sensor malfunction, wiring issues, or a problem with the sensor’s connection to the control board. If the sensor is faulty or the data it provides is incorrect, the system cannot properly regulate refrigerant flow and compressor operation, which can lead to inefficient cooling and potential damage to the compressor. To protect the system, the F8 error prevents the air conditioner from continuing to operate until the sensor issue is resolved. Once the faulty sensor is repaired or replaced, and the system detects normal suction temperature readings, the unit will reset and resume normal operation. Regular maintenance, including checking the condition of the suction temperature sensor and its wiring, can help prevent the F8 error and ensure the Carrier AC runs efficiently without issues.
