The P2 error in Carrier AC indicates that the compressor shell or roof has overheated, triggering a protection mode to prevent damage to the unit. This error is a safety feature designed to safeguard the compressor, which is one of the most vital components in the air conditioning system. When the P2 error occurs, it means that the compressor’s outer shell or roof has reached a dangerously high temperature. Overheating can be caused by several factors, such as poor ventilation, excessive load on the compressor, low refrigerant levels, or a malfunctioning fan. If the compressor shell overheats, it can lead to internal damage or reduced efficiency, which is why the system enters protection mode to prevent further harm. Once the temperature of the compressor shell or roof returns to a safe level and the underlying issue is fixed, the system will reset and the air conditioner will resume normal operation. Regular maintenance, including ensuring proper airflow around the compressor, checking refrigerant levels, and inspecting the fan and other components, can help prevent the P2 error from recurring and ensure the longevity and efficiency of your Carrier AC.
