Error Code
The F1 error code indicates a high-pressure issue in your Haier air conditioning unit. This occurs when the refrigerant pressure is too high for the system to operate correctly.
Dirt or debris on the coils can prevent proper airflow, causing the system to overheat.
Low refrigerant can cause abnormal pressure levels in the system.
The sensor may be malfunctioning and reporting incorrect pressure readings.
Ensure the coils are free from dirt and debris that could block airflow.
Ensure that refrigerant levels are adequate, and top up if necessary.
Consult a technician to check the pressure sensor for faults.
