P4 Error In Carrier

Added on: November 16, 2024

The P4 error in Carrier AC occurs when the system detects an abnormal compressor start or when the compressor is out of step, meaning it is not operating in sync with the system's requirements. This error is often related to issues with the compressor's motor or the electrical components responsible for starting and controlling it. When the P4 error is triggered, it indicates that the compressor failed to start correctly or is not functioning as expected. This could be due to several reasons, including faulty electrical connections, issues with the compressor's start relay, or problems with the inverter or control board that regulate the compressor's operation. The compressor may not reach the proper speed or torque, or it may struggle to start at all, which can lead to an out-of-step condition. To protect the system, the P4 error prevents the compressor from operating further until the issue is resolved. The unit may automatically shut down to avoid damage to the compressor or other components. Once the compressor starts correctly or is brought back into proper operation, the system will reset, and normal functioning can resume. To avoid the P4 error, regular maintenance is important, including checking the electrical connections, ensuring proper operation of the compressor, and inspecting the control board and relays. Addressing any issues with the compressor's starting mechanism promptly can prevent this error and help keep your Carrier AC running smoothly.
