Gree Error Code E4

Gree Error Code E4 typically refers to compressor discharge temperature protection, meaning the compressor is running too hot. Causes include dirty coils, airflow restrictions, fan faults, refrigerant imbalance, or a compressor working under heavy strain.

Symptoms include shutdowns under load, reduced cooling, or the system failing to run during hot afternoons. Because this fault protects your compressor, it should be inspected promptly.
