7 Signs of a Broken Garage Door Spring (and What Not to Do Next)

Published 2026-02-11 6 min read Titan Overhead Garage Doors TX

Almost every garage door that stops lifting has a broken spring, and almost every homeowner's first instinct makes it worse. Here's how to identify it in about thirty seconds, and what to do in the next five minutes.

Why the spring matters more than the opener

People assume the opener lifts the door. It doesn't. A double garage door weighs somewhere between 150 and 350 pounds, and the opener motor is rated to move a fraction of that. The springs carry the weight; the opener just guides a balanced door up and down. Take the springs out of the equation and the opener is trying to deadlift a small motorbike.

That's why a snapped spring feels like a dead opener. The motor runs, strains, and gives up. Nothing is wrong with the opener at all.

The seven signs

1. You heard a loud bang from the garage

Often mistaken for something falling off a shelf, or a gunshot from inside the house. A torsion spring releasing its stored energy in one go is genuinely that loud. If the door stopped working the same day you heard it, you've found your cause.

2. There's a visible gap in the coiled spring

Look at the steel bar running horizontally above the door opening. The spring or springs wound around it should be a continuous tight coil. A broken spring shows a clean two inch gap. This is the single most reliable test and it takes ten seconds from the doorway.

3. The door feels enormously heavy by hand

Pull the emergency release cord (only if the door is fully closed) and try to lift it. A balanced door with intact springs lifts with two fingers and stays where you put it. A door with a broken spring will barely move, or will feel like lifting a loaded fridge.

4. The opener runs for a second, then stops

Modern openers have a force sensor. It detects the impossible load, decides something is obstructing the door, and shuts down to protect the motor. Some flash an error code. That is the opener behaving correctly, not failing.

5. The door opens a few inches and stops

Enough residual spring tension to break the seal, not enough to lift the weight. Very common with dual spring systems where only one spring has gone.

6. The door slams down instead of settling

If you manage to get it up and it drops fast the moment you let go, there's no counterbalance holding it. This is the dangerous version of the symptom and the point at which you stop experimenting.

7. The cables have gone slack or come off the drums

When a spring breaks, the cables often unwind and tangle around the drums at the top corners. That's a second repair on top of the first, and it's part of why we check the whole system rather than swapping the spring in isolation. If yours has done this, you need cable and off track repair as well.

What not to do

Don't keep pressing the remote. Every attempt puts a stripped-gear-shaped hole in your opener's future. A $300 spring job turns into a spring job plus an opener repair because the drive gear gave up trying.

Don't try to force the door up and prop it. A door held up by a bit of timber with no spring tension behind it is a guillotine. People are seriously injured this way every year.

Don't attempt the spring yourself. This is the one job in the trade we'd genuinely tell you to leave alone. A wound torsion spring stores enough energy to break bones, and winding bars slipping is the classic emergency room story. The part is cheap; the technique and the tooling are what you're paying for.

What replacement actually involves

A technician measures four things: wire diameter, inside diameter, overall length and wind direction. Those four numbers determine the spring, and getting them wrong means the door is unbalanced from day one. Then the old spring comes off, the new one goes on and gets wound to the correct number of turns for your door's height, cables and drums get re-set, and the door is balance tested at several points in its travel.

Budget 60 to 90 minutes and $180 to $420 for most residential doors. See our garage door spring repair page for the detail.

Why we replace both springs

If you have two springs, they've done the same number of cycles. Replacing one leaves a mismatched pair, puts the older spring under more strain, and usually buys you a second call out within a year. Doing both at once costs less than two separate visits.

How long should springs last?

Standard springs are rated at 10,000 cycles. One cycle is one open and one close. A household that uses the garage as its main entrance easily does four to six cycles a day, which works out at roughly five to seven years. If you're on your second or third spring failure, ask about a high cycle spring rated at 25,000 or more. The upgrade is modest and it changes the maths considerably.
