Abstract: A powered garage door opener is provided for operating a garage door between an open and closed position. The powered garage door opener comprises a main housing mounted adjacent the garage door. An electric motor and gear train assembly is mounted within the main housing and coupled to the garage door to drive the garage door between the open and closed positions. A power supply is mounted within the main housing and electrically connected to the electric motor and gear train assembly. A control module is mounted within the main housing and electrically connected to the power supply and the electric motor and gear train assembly for controlling selective actuation of the electric motor and gear train assembly. The electric motor and gear train assembly includes a secondary housing, an electric motor sealed within the secondary housing, a worm gear coupled to and driven by the electric motor, a spur gear in meshed engagement with the worm gear, and a driven shaft mounted to the spur gear and coupled to garage door. The electric motor provides electrical power to drive the worm and spur gears, rotating the driven shaft, to provide power actuation of the garage door and the gear relationship between the worm gear and spur gear allows the spur gear to back drive the worm gear and provide manual actuation of the garage door.
