Loud bang from the garage? Door lifting only a few inches? Those are classic broken spring signs — and torsion springs are the one repair you should never attempt yourself.
Your garage door springs are among the hardest-working components in your home — and the most dangerous to touch when they fail. A torsion spring lifts the entire weight of the door, which can easily weigh 150–300 pounds. When that spring snaps, all of that stored tension releases in an instant.
Recognizing the early warning signs can save you from a dangerous failure and an expensive emergency repair. Here's what homeowners should watch — and listen — for.
Dealing with a snapped cable or broken spring? Do NOT attempt to pull the red release cord while the door is open. Call our emergency techs at 713-9999161.
When a torsion spring breaks, it releases its stored energy with a bang that's often mistaken for a gunshot, a car hitting the house, or something falling on the roof. If you hear that noise and your door stops working, assume the spring has snapped.
Look at the horizontal shaft above the closed door. A healthy torsion spring is a continuous, tightly wound coil. A broken spring shows a visible gap of 2–4 inches where the coil separated.
Openers are designed with a safety limit: if the door is too heavy, the opener stops and reverses. A door with a broken spring rises 6–12 inches and then stops. This is the opener protecting itself — and you.
With the opener disengaged (door fully closed), a balanced door should lift smoothly with one hand. If the door feels like dead weight, the springs have lost their tension or failed completely.
A door that binds, leans to one side, or slams down is often working on one functioning spring — a failure waiting to happen.
WARNING: A torsion spring is under extreme tension — enough to break bones, cause severe lacerations, or worse. Never attempt to loosen, adjust, wind, or remove torsion springs yourself. Do not use winding bars, power tools, or improvised tools on the spring cone. This is the single most dangerous repair on a garage door, and it should only be done by a trained technician with the proper winding bars, clamps, and safety equipment.
Also, never release the emergency cord on a door with a broken spring while the door is open — the door can crash down with full force.
No. The opener will strain and may burn out, and manually lifting an unbalanced heavy door is a real injury risk. Stop using the door until it's repaired.
Most standard springs are rated for about 10,000 open/close cycles — roughly 7–10 years for a typical household. Cycles above that are working on borrowed time.
Cold temperatures make steel brittle, and rapid temperature swings stress already-worn coils. That's why spring failures spike during the first cold snaps.
Yes — both springs were installed at the same time and have the same wear. Replacing both restores balance and prevents a second service call in a few months.
