Motor and Gearbox Assemblies
When your garage door opener motor stops working, replace it with an inexpensive motor and gearbox assembly from Garage Door Supply Company. The motor gear is part of the garage door opener motor, attached to the motor by a sprocket shaft. Replacing a worn or damaged motor and gearbox is cheaper than replacing the whole garage door opener. While installation instructions are included with most of our LiftMaster motor and gearbox assemblies, you have another advantage when you shop with us.
