Air Door Actuator / Motor: Description and Operation
Recirculation Door Actuator - Description
DESCRIPTION
The recirculation door actuator (1) is a reversible, 12 volt direct current (DC) servo motor, which is connected directly to the pivot shaft lever of the
recirculation-air door. The recirculation door actuator is located on the right side of the HVAC air inlet housing.
The recirculation door actuator is contained within a black molded plastic housing with an integral wire connector receptacle (2), an output shaft with
splines (3) that connect it to the recirculation door and three integral mounting tabs (4) that allow the actuator to be secured to the air inlet housing. The
recirculation door actuator does not require mechanical indexing to the recirculation-air door, as it is electronically calibrated by the A/C-heater control.
