This shaft pin is a common wear-and-tear replacement item in Daikin indoor air conditioning units. When the horizontal vane fails to stay in position, swings freely, or makes noise during operation, a worn or broken vane shaft is often the cause. Replacing it with this genuine Daikin part restores proper airflow direction and vane control.
