What to do if the airflow direction of the Mijia Air Conditioner Pro Eco A+++ 9K cannot be changed?

If the airflow direction of the Mijia Air Conditioner Pro Eco A+++ 9K does not change, follow these steps:
1. Ensure that the swing function is enabled on the remote control or through the Mi Home/Xiaomi Home APP. If this setting is turned off, the air guide blade will remain fixed and not move to adjust airflow direction;
2. Visually inspect the air guide blade on the indoor unit to check if it is stuck or blocked. Dust buildup, foreign objects, or mechanical obstruction will prevent it from moving. If you find any blockage, gently remove it and restart the unit;
3. Try turning the air conditioner off, wait for 3 to 5 minutes, and then turn it back on. This can help reset the internal controls and restore blade movement.
If the issue persists, please contact the after-sales service for further inspection.
