7 Signs of a Broken Garage Door Spring
Broken torsion springs cause more dead garage doors than anything else. Learn the seven warning signs, what to do immediately, and why springs get replaced in pairs.
Springs do the real work in a garage door. The opener only guides a door that the springs have already made nearly weightless — which is why a snapped spring turns a 200-pound door into 200 pounds the opener was never built to lift.
The seven signs
- A loud bang from the garage, often mistaken for a gunshot or something falling off a shelf. That's the spring letting go.
- A visible gap in the coil. Look at the shaft above the door — a broken torsion spring shows a clean one- or two-inch separation.
- The door lifts a few inches and stops. The opener hits its force limit and gives up.
- The door feels impossibly heavy by hand with the emergency release pulled.
- The door slams down fast instead of settling under control.
- The door hangs crooked in the opening, one side higher than the other.
- Loose, slack or shredded cables, which usually follow within a cycle or two of a spring failure.
What to do right now
Leave the door in whatever position it's in. If it's down, leave it down. If it's up, don't stand or park under it. Stop using the opener entirely — every press with a broken spring strains the motor, chews the drive gear and can shred the cables.
Why both springs get replaced
On a two-spring door, the surviving spring has exactly the same age and cycle count as the one that failed. Replacing only the broken one means paying a second call-out fee within months, and it leaves the door unbalanced in the meantime. We replace them as a matched pair.
How long springs are supposed to last
A standard spring is rated for roughly 10,000 cycles — about seven to ten years for a typical household, less if you're in and out four or five times a day. High-cycle springs rated to 25,000 or 50,000 cycles cost a little more and last far longer, which makes them a genuine upgrade rather than an upsell on a busy door.
Why springs break in winter
Cold steel is brittle steel. Most of our spring calls across Idaho land between December and March, and a spring that was already near the end of its cycle life will typically choose the coldest morning of the year to finish.
