At least once a year a simple test should be preformed to check to see if you garage door springs are good. If you manually open your garage door half way the door should stay in the position that its left in. Sometimes a small adjustment can be made with the cables to add or minus tension on the springs. always remember before attempting to adjust or change your extension springs you must have the garage door completely opened to insure that the tension is off of the garage door springs.
The average spring life is 6-8 years. However, with the increasing popularity of garage doors being used as the front doors, springs may last only 3-5 years. However, there have been instances where springs have broken in as less than a year. This should not occur if the springs were installed properly. This is one of the many reasons you should be sure to purchase springs from a reputable company and get a warranty.
Extension springs, are wound coils, wrapped tightly together to create tension. Extension springs usually have hooks, loops, or end coils that are pulled out and formed from each end of the body. Garage door extension springs counterbalance the weight of garage doors to make them easy to open and close. Extension springs are stretched with cables and pulleys. One end of the cable attaches to the bottom of the door; the other end of the cable is secured to the horizontal track angle with a s-hook.
Torsion Garage Door Springs
Torsion garage door springs are most common. They use torque springs, which are tightly wound coils of metal, to generate the torque that's needed to lift the garage door up when you open it. Torsion Springs are mounted above the garage door opening with a metal shaft running in the middle to support the spring. A standard torsion spring has a stationary cone which secures the spring to the spring anchor bracket. Since this bracket is secured to the wall, the stationary cone, as its name suggests, does not move. The other end of the torsion spring has a winding cone. This winding cone is used when installing, adjusting, and uninstalling the springs. When installing the torsion spring, the coils of the spring are wound up to create a lot of torque. Torsion springs come in sets of between one and four, depending on the weight and size of the door. Lighter doors typically have only one spring while heavier doors use two or more. Torsion Springs require fewer parts and are more durable and less dangerous when they break than extension springs.
