Garage door automation is a motorized device that opens and closes garage doors. Most are controlled by switches on the garage wall, as well as by remote controls carried by the owner.

The typical electric garage door motor consists of a power unit that contains the electric motor. The power unit attaches to a track. A carriage connected to an L-shaped arm that attaches to the top of the garage door slides back and forth on the track, thus opening and closing the garage door. The carriage is pulled along the track by a chain, belt, or screw that turns when the motor is operated. A quick-release mechanism is attached to the carriage to allow the garage door to be disconnected from the opener for manual operation during a power failure or in case of emergency. Limit switches on the power unit control the distance the garage door opens and closes once the motor receives a signal from the remote control or wall push button to operate the door.
