Quick answer: Cold makes steel more brittle, so a spring already near the end of its life often snaps on the first freezing morning. It is one of the most common service calls we get each winter.
The loud bang some Morristown homeowners hear from the garage is often a spring snapping. This guide explains why springs break and the right way to handle it. For garage door repair in Morristown, NJ, call (973) 250-4214 for a free estimate.
Springs are rated in cycles — one up-and-down is a cycle, and a standard spring lasts about 10,000 of them, or 7-10 years for a typical family. Rust from {state} humidity, cold snaps that make steel brittle, poor balance, and undersized springs all shorten that life.
If your door has two springs and one broke, replace both. They share the same cycle life, so the second is right behind the first, and doing both at once saves a second service call. A good technician also checks the cables and bearings while they are there.
A two-to-three-inch gap in the coil, a door that opens a few inches then stops, an opener that strains or reverses, or a door that feels like dead weight by hand all point to a spring. You don't always hear the bang.
Torsion springs sit on a bar above the door, last longer, and balance the door more smoothly — the modern standard. Extension springs run along the horizontal tracks and should always have a safety cable so broken pieces can't fly. Knowing which you have helps describe the problem.
Most modern doors use torsion springs mounted on a shaft above the opening; older or lighter doors use extension springs along the tracks. As the door closes the springs wind and store energy, then release it to lift the door. That stored energy is what makes a heavy door feel light.
Why did my spring break in the cold?
Cold makes steel more brittle, so a spring already near the end of its life often snaps on the first freezing morning. It is one of the most common service calls we get each winter.
Can I replace a garage door spring myself?
