A garage door opener works with motors that are responsible for the opening and closing of garage doors. Mostly, the garage door openers have been repaired by simply aligning the photo eyes or replacing the sprockets or warn gears that are present inside the garage door opener. Other repairs that are common with the garage door opener are the trolleys, motor, drive trains, circuit boards, drive belts, limit switches and some more. In some of the cases, with a little adjustment in the existing parts, the garage door comes back in the working order requiring no additional part and thus no additional cost.
