P9 Error Code: Outdoor Unit Compressor Drive Overload Protection
If any of the following occurs while the compressor is starting or running, the outdoor unit stops and the system displays error code "P9":
- The control board does not receive a feedback signal from the compressor.
- The control board detects an abnormal signal from the compressor.
- The compressor fails to start normally.
The system then attempts to restart up to six times. If the compressor still does not operate normally, it displays the error code again.
