Wolf Garage Door Services teamSprings do the heavy lifting on a garage door. The opener only guides a door that the springs have already made light. When one snaps, the door suddenly weighs what it really weighs, often well over 100 pounds for a two-car steel door.
Below is a short plan: how to confirm it's the spring, what to do with the car and the opener, what to leave alone, and what a proper repair looks like.
Confirm it's the spring
Look above the closed door. On a torsion system you'll see a steel bar running across the header with one or two coiled springs on it. A broken one shows a clear gap of a few inches somewhere in the coil, as if it was cut.
On older doors with extension springs, the springs run along the horizontal tracks near the ceiling. A broken one hangs loose or lies on the floor, and the safety cable through its center should be holding it.
- The opener motor runs but the door rises an inch or two, then stops
- The door feels nailed to the floor when you try to lift it
- One side of the door sits lower than the other
- A cable hangs slack beside the track
What to do in the first hour
- Stop pressing the remote. Each attempt strains the opener's gears and can pull cables off their drums.
- Unplug the opener so nobody in the house tries it again.
- Keep people and pets out from under the door.
- A closed door can stay closed. Shut, it's safe and the house stays secure.
- Need the car out? Call first. Lifting a spring-less door by hand takes two strong adults, and letting it drop can injure someone or bend the bottom section.
If the door stopped partway up, pulling the emergency release disconnects it from the opener. With no working spring, it can free-fall to the floor. Leave it attached and keep clear.
What not to touch
The parts that look simple are the ones that hurt people. Leave these to a technician with winding bars and the right clamps:
- The set screws on the spring cones and the cable drums
- The bottom brackets where the lift cables attach
- The remaining good spring, which is still fully loaded
A torsion spring stores enough energy to snap a screwdriver or a wrist. YouTube makes it look quick because the person filming has done it hundreds of times.
How the repair goes
A tech clamps the door to the track, unloads the remaining spring, and removes both from the shaft. New springs are sized to your door's weight, height and drum size rather than picked off a shelf by guesswork.
After winding, the tech checks the cables, drums, bearings and rollers, then lifts the door by hand. A balanced door stays put at about waist height. Only then is the opener reconnected and its force setting checked. See our spring repair service for what that visit covers.
Why replace both springs
On a two-spring door, both went in together and have opened the door the same number of times. If one broke, the other is close behind. Replacing the pair keeps the door balanced and saves a second service call a few months later.
| Option | What happens next |
|---|---|
| Replace one spring | New and worn springs pull unevenly; the old one often fails soon after |
| Replace both | Even tension on both sides, one visit, matched wear going forward |

Frequently asked questions
Is it OK to lift the door by hand with a snapped spring?
Technically yes, but it isn't a good idea. The door may weigh more than 100 pounds without spring help, and it can drop fast if your grip slips. If the car has to come out, two adults should lift it slowly and prop it securely, or wait for a technician.
Is it safe to leave the door closed overnight?
Yes. A closed door with a broken spring is stable and still locks your garage. Unplug the opener so nobody tries to run it, and keep the area clear until the repair.
Why did my spring break with no warning?
Springs wear a little with every open and close cycle, and the steel eventually fatigues. Rust speeds that up, especially near the coast. Cold mornings and a door that was already out of balance can also be the last straw.
Do I need a new opener too?
Usually not. If the opener ran against a heavy door for a while, the gear or trolley can wear. The technician tests it after the new springs are in and will tell you if anything else needs attention before doing the work.
