The P8 error in Carrier AC occurs when the system detects high temperatures in the compressor discharge pipe, triggering a protection mode to prevent damage to the compressor. This error is a safety feature that helps protect the compressor from overheating, which could lead to serious damage or reduced efficiency. When the P8 error is triggered, it means the compressor discharge pipe is reaching dangerously high temperatures. This could be caused by several issues, such as a refrigerant leak, low refrigerant levels, poor airflow, or a malfunctioning compressor. If the refrigerant is insufficient or not circulating properly, the compressor may overheat, causing the discharge pipe to reach high temperatures. To protect the system, the P8 error shuts down the compressor until the temperature returns to a safe level. Once the issue is resolved—whether it’s fixing refrigerant levels, clearing airflow obstructions, or addressing any other underlying cause—the system will reset, and the unit can resume normal operation. Regular maintenance, including checking refrigerant levels, ensuring proper airflow, and inspecting the compressor, can help prevent the P8 error and keep your Carrier AC running efficiently.
