How Garage Door Springs Work

Garage door springs are found in all garage doos, In contemporary homes, a garage is a standard feature. Each day, as you pull your vehicle in and out of the garage, the door opens and closes with the click of a button, but have you ever considered the mechanics behind this technological marvel?

When you push the power button, a chain of events is set in motion that results in the raising or lowering of the door. While all the parts of the garage door opener must work in unison for it to operate effectively, arguably no part of the opener is as important as the garage door springs.

There are two different types of springs used on garage doors: the extension spring and the torsion spring.

The extension spring has been used for a long time, but it’s not without its faults. A superior option, and the one that’s now most commonly used, is the torsion spring system.

What is a Garage Door Spring?

Most garage doors weigh over 130 pounds, and the motor can’t comfortably lift all that weight by itself. The purpose of a garage door torsion spring is to help the cables and motor operate the door.

Garage door torsion springs are mounted above the garage door, and they look like a simple horizontal bar. When the garage door closes, the torsion spring twists and tightens, storing energy. When the garage door opens, the energy is released from the torsion spring as it untwists. This release of energy helps to lift the garage door’s weight. Thanks to the torsion spring, it does not take as much effort for the motor to open the garage door.

Garage door torsion springs are not a one-size-fits-all piece of equipment, however. Various springs are made to work with different garage doors. They are manufactured to accommodate the varying weight, thickness, and design elements of a range of garage doors.

A torsion spring intended for a small one-car garage door will not be able to store enough energy to operate the door of a two-car garage. It is crucial to use the correct type of torsion spring for your specific situation. Commercial doors usually use very large springs while residential have smaller ones 

Unfortunately, no matter what precautions you take, eventually torsion springs will begin to develop problems. Factors such as the repeated opening and closing of the garage door, exposure to the elements, as well as simple age-related issues, are common causes of torsion spring malfunctions.

A garage door torsion spring that’s damaged will become weaker until it no longer works effectively. When the spring is not able to store the necessary energy, opening the garage door will become increasingly difficult.

If the spring becomes defective, it can cause considerable damage to your property and even pose a danger to you, because a weak torsion spring can’t handle the weight of the garage door.

This means the door could slam down unexpectedly, even if something or someone is below it. You can’t be too careful when a spring shows signs of wear, and you should act promptly to avoid a nasty accident.

The replacement of a torsion spring is not a project that you can complete through an online search and a DIY fix.

These doors can be under a great deal of pressure. Many weekend warriors have wound up in a great deal of pain while trying to fix their garage door torsion springs, so this is a job that’s best left to the professional garage door technicians—unless you want to land in the hands of a medical professional.
