Abstract
An exemplary door control assembly includes a door control and an armature assembly. The door control includes a body and a pinion rotatably mounted to the body for rotation about a rotational axis. The pinion has a radially-outer periphery and a recess is formed in the radially-outer periphery. The armature assembly comprises an armature and a coupler. The armature is rotationally coupled with the pinion, and includes an opening in which the pinion is received. The coupler is movably mounted to the armature for movement between a coupling position and a decoupling position. With the coupler in the coupling position, the coupler projects into the recess and axially couples the armature and the pinion to prevent removal of the armature from the pinion. With the coupler in the decoupling position, the coupler axially decouples the armature and the pinion to permit removal of the armature from the pinion.
