LG Heat Pump Error Code P713
Outdoor unit SUMP DOWN 1 protection control (SUMP temperature maintains over 95°C for 5 minutes).
What the P713 error code actually means
This error means the heat pump detected that a temperature-sensitive area at the base of the outdoor unit's compressor got dangerously hot and stayed that way for too long. The system shut itself down to prevent serious internal damage. A technician needs to inspect the compressor and a related control valve before the unit is safely restarted.
