Even the smallest and lightest of steel garage doors weigh in at about 100 pounds. Others are heavier, depending on the size, type of material used, different types of glass, etc. In order to make it operable by hand, or by an opener, it needs a counter balance system. That's where the springs come in. They provide the force necessary to make such a heavy object functional. There are two types commonly used in residential settings: torsion and extension.

Torsion springs are usually installed on larger or heavier garage doors. Most models wide enough for two cars will commonly have this type. They're found on the wall above the opening, and look like a long metal coil. Most people barely notice them until one breaks, and everything becomes too heavy to lift. When it has broken, you'll see the separation in the coils. You'll need professional service for this kind of repair. The counter balance system is under extreme tension, and for that reason, homeowners should never attempt to adjust or repair any of it's components. Additionally, forcing the opener to pull too much weight can damage the opener, and the top panel where it's attached.

Extension springs are usually found on garage doors that are wide enough for only one car. These can be found nearly parallel to the tracks near the ceiling, one on each side. Many times, the extension type will relax to the point that they need replacement, instead of actually breaking. When this happens you can usually see repeated gaps in the coils, and you may consider having them serviced or replaced. Extension systems, while more inexpensive to install and maintain than torsion, are not suitable for installation on models wide enough for two cars due to the lack of balance. Torsion systems use the shaft, along with the drums and cables, to provide equal amounts of lift on each side. Extension springs are independent of each other, and require proper tension to ensure level operation. One advantage of having extension, is the ease of replacement. Local hardware stores typically carry them, and a do it yourself job is possible for those who are mechanically inclined. Don't forget to use caution, as the extension counter balance system is also under extreme pressure, and can cause injury or death.
