Pushing a button to open your garage door before going to work seems trivial until the motor fails to lift the door. There are various explanations for a garage door malfunction, but this paper will focus on the most common of them all—a broken spring. Inspired by the fact that garage door technicians must match the right spring to the appropriate garage doors, this project produced a spring conversion calculator. This paper provides a preface and comprehensive explanation of the mechanisms of overhead garage doors. Initially, it introduces the garage door and its components, then provides a detailed explanation of a door’s lifting mechanisms, and lastly, elaborates on spring theory, focusing on the physics and calculations of spring properties.
