The adaptive airflow system consists of the active chamber exhaust, filter switch flap, automatic top vent, and air duct. When the vents that make up the air duct system do not move in place or maintain normally, the adaptive air duct system cannot successfully switch to the corresponding air duct mode. This fault code means that the adaptive air duct system cannot successfully enter the cooling mode, and the fault needs to be eliminated in combination with the specific vents with abnormal movement.

In cooling mode, the opening and closing of the active chamber exhaust and the automatic top vent are related to the opening and closing of the chamber exhaust fan, while the filter flap will remain open.
When the chamber exhaust fan is turned on, the active chamber exhaust and the automatic top vent are opened;
When the chamber exhaust fan is turned off, the automatic chamber exhaust and the automatic top vent are closed;
The filter switch flap is always open
Therefore, when you encounter this error, please first check whether it is an abnormal vent to narrow the scope of the fault.
Users may adjust the order of these solutions as needed.
When an error occurs, please first check which vent is faulty, causing the abnormality.
