How Garage Door Springs Work

Springs do the heavy lifting for your garage door. A standard garage door weighs between 130 and 400 pounds. The springs store tension and use that energy to lift the door when you open it. Without working springs, your garage door opener motor alone cannot move the door safely.

Torsion Springs vs. Extension Springs

There are two types of garage door springs. Knowing which one you have helps you understand the repair.

Torsion springs are mounted horizontally above the door opening. They twist and store energy as the door closes. Most modern homes use torsion springs. They tend to last longer and are generally considered safer than extension springs.

Extension springs run along the sides of the door, above the horizontal tracks. They stretch and contract as the door moves. These are more common in older homes and lighter doors. They also require safety cables to prevent the spring from flying loose if it breaks.

Signs Your Garage Door Spring Is Broken

Knowing what to look for can save you time and prevent further damage. Watch for these warning signs.

Common Warning Signs

You hear a loud bang coming from your garage. This is one of the most common signs a spring has snapped. It often sounds like a firecracker or a gunshot.

Your garage door only opens a few inches and then stops. The opener might be working fine, but the door feels too heavy to move. This is a classic sign of a broken torsion spring.

You see a visible gap in the spring. A broken torsion spring will have a clear separation in the coil. You can usually spot it by looking above the door.

The door looks crooked or lopsided when you try to open it. This often happens when only one extension spring breaks and the other is still holding tension on one side.

The cables on your door look loose or are hanging down. When a spring breaks, the cables that connect to the bottom of the door can go slack. garage door cable replacement may also be needed if the cables have been damaged in the process.

Why DIY Spring Replacement Is Dangerous

You will find plenty of tutorials online showing how to replace garage door springs yourself. But the truth is, this repair carries real risk. Springs are wound under hundreds of pounds of tension. If a spring slips or releases suddenly, it can cause broken bones, deep cuts, or worse.

What Professionals Do Differently

A trained technician has the right tools and knows how to release tension from the spring safely before starting any work. They also know how to set the correct tension when installing the new spring. Too much or too little tension affects how your door operates and can shorten the life of the new spring.

Professionals also inspect the cables, drums, and other hardware while they are working. A broken spring sometimes points to wear in other parts. Catching those problems early prevents another breakdown soon after the repair. Learn more about why garage door springs break and what wear factors to watch for.

Should You Replace One Spring or Both?

If your garage door has two springs and one breaks, it is smart to replace both at the same time. Springs wear at roughly the same rate. If one broke, the other is likely close behind. Replacing both now saves you from paying for a second service call in a few months.

Most residential torsion springs are rated for 10,000 cycles. One cycle equals one open and one close. A family that uses the garage four times a day will go through about 1,460 cycles per year. That means an average spring lasts around seven years. For a deeper look at how often springs should be replaced, Kooler Garage Doors breaks down the numbers by usage.
