Mitsubishi Electric Error Code P1

Mitsubishi Electric Error Code P1 often indicates high pressure protection, meaning refrigerant pressure has risen above safe limits. Causes include dirty outdoor coils, blocked airflow, outdoor fan faults, refrigerant overcharge, or internal restrictions.

Symptoms include poor cooling, shutdowns under load, and difficulty restarting. Repeated P1 faults can strain the compressor, so prompt repair is recommended.
