The F3 error in Carrier AC indicates a compressor discharge pipe temperature sensor error, meaning that the sensor monitoring the temperature of the refrigerant gas as it exits the compressor is malfunctioning or providing incorrect readings. This sensor is crucial for ensuring that the refrigerant is at the correct temperature as it moves through the system, preventing overheating or inefficiencies in cooling. When the F3 error is triggered, it suggests that the compressor discharge pipe temperature sensor is either faulty, disconnected, or reading abnormal temperatures. This could be caused by issues such as a damaged sensor, a wiring fault, or a malfunction in the control board that processes the sensor’s data. If the sensor is not working correctly, the system may not be able to properly regulate the compressor’s operation, potentially leading to damage or reduced performance. To protect the system, the F3 error will cause the air conditioner to stop operating to prevent further damage. Once the issue with the sensor is fixed—whether by replacing the faulty sensor or repairing wiring—the system will reset and resume normal operation. Regular maintenance, including checking the compressor discharge pipe temperature sensor and ensuring all wiring and connections are intact, can help prevent the F3 error and ensure the Carrier AC operates smoothly.
