When it is a spring-break down in your garage door, it could be a serious issue to you or other objects in your garage door. Springs in your overhead door play a vital role in operating it. There are two types of springs mounted in your garage door. One is torsion spring installed in a steel tube over the top of the door that helps to transfer the weight of the door to the anchor plate. Another is extension spring that is placed each side of the door. The springs enable you to operate your garage door efficiently.
