Carrier Error Code P1

If your Carrier unit displays Error Code P1, it generally indicates high pressure protection, meaning refrigerant pressure is too high. Common causes include dirty outdoor coils, blocked airflow, outdoor fan faults, refrigerant overcharge, or internal restrictions.

Symptoms include reduced cooling/heating and system shutdown. High pressure issues should be fixed quickly to prevent compressor strain and long-term damage.
