Could a Garage Door Spring Be Failing in Killeen?

Probably, if the door suddenly feels very heavy, rises only a few inches, or you heard a loud bang from the garage. Those are the classic signs of a broken spring. Slower signs, like a door that drifts down when left half open or an opener that strains, can point to a spring that is wearing out. Springs hold the door's weight under high tension, so look and listen, but leave the hands-on work to a pro.

How the springs do their job

The springs, not the opener, do most of the lifting. They store energy as the door closes and release it as the door opens, so the opener only has to guide the door.

Most homes have one of two systems:

• Torsion springs sit on a steel bar mounted above the door opening. They wind up as the door closes. Many doors have one; wider or heavier doors usually have two.
• Extension springs run along the horizontal tracks on each side, near the ceiling. They stretch as the door closes. DASMA recommends a safety cable through each extension spring so a broken spring can't whip loose.

Springs are rated in cycles (one open plus one close). How fast one wears out depends on that rating, the weight it carries and how often the door runs.

Warning signs of a broken spring

• A loud bang from the garage, often when nobody is using the door.
• The door won't lift, or the opener runs and the door rises only a few inches before stopping.
• A visible gap in a torsion spring, where the coil has separated into two pieces.
• Slack or dangling cables on one or both sides.
• The door looks crooked as it moves, or one side rises before the other.
• The door falls quickly when it's lowered, instead of coming down at an even speed.

If you see any of these, stop using the opener. Running an opener against a broken spring makes the motor lift the full weight of the door, which can damage the opener and leave the door hanging unevenly. Our door won't open guide covers what to do if your car is stuck inside.

Signs a spring is wearing out

A spring often gives warnings before it breaks:

• the opener sounds like it is working harder than it used to;
• the door won't stay put when partly open, and drifts down or creeps up;
• you can see rust on the coils;
• the coils grind or squeak as they wind and unwind.

DASMA's homeowner maintenance guide describes a balance check: a properly balanced door, operated by hand, should stay partly open about 3–4 feet above the floor. If yours falls or shoots up, the springs likely need adjustment or replacement. Pull the manual release only with the door fully closed, and keep clear if the door will not stay put. If you already suspect a broken spring, skip this check and call a pro.

What wears springs out faster in Central Texas

DASMA's technical data sheet on spring cycle life names a few factors that apply here:

• Heat and humidity. Doors left open for long periods expose the springs to more heat and moisture, so keep the door closed when you can.
• Rust. Surface rust reduces the strength of the spring wire and can start fatigue cracks.
• Skipped lubrication. The door maker's instructions usually call for periodic spring lubrication.

Our Central Texas weather guide covers the rest of the door.

What to tell the contractor

A clear description helps a local pro bring the right parts. Note:

• whether you have torsion springs above the door or extension springs along the tracks;
• whether you have one torsion spring or two;
• what you saw or heard, and when;
• whether the door is stuck open, closed or partway.

Take photos from a safe distance. Do not touch the springs, cables or the brackets at the bottom corners of the door. DASMA warns that those parts are under high tension and should be adjusted only by trained technicians.

When the quote comes back, ask what spring size and cycle rating it includes. On a two-spring door, DASMA advises replacing both even if only one broke. Our spring repair page explains how to compare the proposed work.

Common questions

What does a broken torsion spring look like?

Look at the bar above the door from a safe distance. A broken torsion spring usually shows a gap where the coil has split into two pieces, and the lift cables may hang slack. Take a photo and leave it to a pro.

How long do garage door springs last?

It depends on the spring's cycle rating and how often the door runs. A busy door that opens many times a day wears its springs out sooner. Ask for a higher-cycle spring if your household uses the door heavily.

Why does my garage door close too fast?

A door that drops quickly instead of lowering at an even speed often has a weak or broken spring. Chamberlain's manual warns that weak or broken springs can make a door fall rapidly and unexpectedly, so stop using it, keep clear and have a pro check the springs.
