One of the most likely components of an overhead garage door to fail is the garage door spring. These springs normally come in two different categories: A Torsion spring or an Extension spring. Failure of either type can result in considerable damage to the door or even possible injury to the home or business owner. We recommend that you have your garage door springs checked if your overhead door is more than a few years old. Business owners especially need to avoid failures that can lead to very costly liability issues.
The spring acts as a counterbalance to the weight of the door. This allows the door to open and close without exerting excessive force. The theory isn't complicated. It is the same as the use of counterweights in castle drawbridges centuries ago. Due to the torque requirements in a spring to make it function properly, repairs and replacement of these parts can be a dangerous undertaking. According to the US Consumer Product Safety Commission an average of 30,000 accidents per year are attributed to garage doors.

Garage door torsion springs work in conjunction with a metal shaft located at the top of the overhead door. The shaft normally passes through the spring but in some cases it may house the spring. It will be mounted to the center or at one end of the shaft. The wire size, diameter and length of the spring will determine the amount of lift available and the life cycle. The industry standard is 10-15,000 cycles for new doors. This can be increased by using a larger wire size. Torsion springs are manufactured using five different designs:
Extension springs stretch and contract to help open and close the garage door. They are usually mounted along the sides of the door or above the horizontal roller tracks. Residential applications of normally use two springs, one on each side of the door. One end is fixed and the other connects to a pulley. There is not a standard extension spring. Each manufacturer has their own design, characterized by weight in 10 pound increments. Commercial and industrial overhead doors use heavier extension springs in increments of 20 pounds.
The garage door height will determine the required length of the spring. The range of the extensions spring�s length needs to equal � of the height of the door.
