Garage door springs aren’t usually given much thought by homeowners, at least not until they break. But, the springs are actually a critical component of the garage door system, coming into play every time you open or close the door.

It is often assumed that the garage door opener lifts and lowers the door, which might weigh hundreds of pounds. However, in reality, the motor only bears a small part of the load. It is the spring (or springs) that do most of the work. Indeed, the garage door springs store large amounts of mechanical energy that gets released to lift the massive weight of the door and is returned to the spring when the door is lowered. If the opener motor ever fails, you try to lift up the door yourself (after disengaging the opener), and you’ll see it’s actually very easy – precisely because the springs are doing most of the lifting!

Due to the huge amount of energy stored in a tightened garage door spring, it can be a potentially dangerous object. A snapping spring under tension can cause serious personal injury, or damage to property, for example, your car or the garage door itself. Also, a broken spring cannot support the weight of the door, which could come crashing down to the floor.

Broken garage door spring

Thus, for safety reasons, we strongly recommend that only trained professionals should undertake garage door spring repair or replacement tasks. The springs must be handled properly, plus it’s extremely important to use only parts of the right size and length for your particular installation. It is not a do-it-yourself project!

Garage door springs come in two main types: Torsion, and Extension. Extension springs are more common in residential installations because they cost less. But, torsion springs are sturdier, able to support more weight, offer greater balance, operate more smoothly, and tend to last longer. Let’s explore how each type works.

Broken Torsion Garage Door Spring Repair

Torsion springs store energy by using a rotating or twisting motion around a shaft. The spring is positioned horizontally over the closed door, with pulleys on each end of the shaft attached to cables. When the motor is activated, the spring uncoils, releasing its energy to lift the door. The pulleys rotate and pull the cables which lift the door on each side. When the door is lowered, the process reverses, with the weight of the descending door forcing the spring to wind up again.

Broken torsion spring

Torsion springs store tremendous amounts of energy. However, like all springs, they do weaken with age, may be susceptible to rust and extreme temperatures, and could eventually break after many thousands of cycles operating the door. A garage door with a broken torsion spring can fall rapidly, and should always be repaired by a trained technician.

Torsion springs also come in a wide range of options, in terms of coil diameter, length, wire size, and wind direction (clockwise or counter-clockwise), that have been specifically selected for your door setup, weight, height, etc., making use of the correct parts especially important.

Extension Springs

Extension springs store energy by being extended or stretched, which they resist when pulled (like an elastic band). They are usually located above the horizontal tracks on both sides of the door. Extension springs store less energy than torsion springs, so a pair of extension springs must work together to lift the door, and due to their less controlled nature may experience more jerking motion. They are in the extended (pulled tight) position when the door is down, and relaxed when the door is up.

Extension spring systems, because they have more exposed parts, are considered not quite as safe as torsion springs while in operation. To be safe, every garage door extension spring should be installed with a safety cable running through the spring and connected to parts of the track. This prevents a spring that snaps or a cable or bracket that let’s go, from causing the spring to slingshot and dangerously hitting someone or something.

We want to emphasize, again, that all garage door springs, regardless of type, operate under extreme tension, and should only be repaired or replaced by knowledgeable technicians. In the case of extension springs, of one is broken, the other one will probably snap soon, so it is recommended to change both at the same time. You might consider replacing the cables at the same time, for greater peace of mind.
