How to Tell If Your Garage Door Spring Is Broken
A broken garage door spring usually announces itself with a loud bang from the garage, followed by a door that won't open or feels impossibly heavy. The clearest signs are a visible gap in the coiled spring above the door, a door that opens only a few inches before stopping, and an opener that strains, hums, or reverses without lifting. Until it's fixed, stop using the door and don't try to force it open.
Step by step

Listen for the bang and check the spring for a visible gap
When a torsion spring snaps, it usually makes a sound like a firecracker or a gunshot, loud enough that people often think someone broke in. Look at the long spring (or pair of springs) mounted on the metal bar above the door. A broken one will have a clear 1-to-2-inch gap where the coils separated. If you have extension springs running along the tracks instead, look for a spring that's hanging loose or stretched out of shape.

Try to lift the door by hand with the opener disconnected
Pull the red emergency release cord to disconnect the opener, then try lifting the door manually. A healthy door is counterbalanced by the springs and should feel light, maybe 8 to 10 pounds, and stay put when you let go halfway up. If it feels like you're deadlifting 100-plus pounds or it slams back down the moment you release it, the spring has lost its tension and is broken or failing.

Watch what the opener does when you hit the button
A motor that hums, strains, lifts the door a few inches, or starts up and then reverses is almost always fighting a dead spring, not a bad motor. The opener is only built to guide the door, not carry its full weight, so it gives up fast. If the door rises a few inches at an angle and stops, that's a classic broken-spring signature. Stop pressing the button so you don't burn out the opener.

Look for crooked movement, slack cables, or a door stuck near the floor
With one of two springs broken, the door may lift unevenly, look crooked in the opening, or jam in the tracks. Check the lift cables on both sides too. When a spring breaks, the cables often go slack, slip off the drum, or hang loose. A door that traveled down and now sits flat on the ground refusing to budge is another strong sign the counterbalance is gone.

Rule out the simple stuff before you commit to a spring
Make sure the opener has power and the wall button and remotes work, since a tripped GFCI or unplugged unit can mimic a failure. Check that the manual lock isn't engaged and that nothing is blocking the tracks. If the door is light and lifts normally by hand but the opener won't run, your problem is likely the opener, not the spring. If the door is heavy and the spring shows a gap, it's the spring.
When to call a pro
Call a pro the moment you confirm a broken spring. Torsion springs hold tremendous tension and can cause serious injury, so replacement is a job for a trained garage door technician, not a DIY fix.

Is it safe to open my garage door with a broken spring?
No. Without the spring counterbalancing the weight, the door can be 100 to 300-plus pounds and may crash down suddenly, which can injure someone or damage the door. Don't force it, and don't park your car under or behind it. If you absolutely must move the door, get two people and prop it securely, but the safer move is to leave it alone and call a technician.
Can I just replace one spring if I have two?
We don't recommend it. Springs wear at the same rate, so if one broke, the other is usually close behind. Replacing both at once means you avoid a second service call within weeks, the door stays balanced, and the new springs are matched to each other. The labor is largely the same whether the tech replaces one or both, so doing both is the better value.
How long do garage door springs last?
Most standard springs are rated for about 10,000 open-close cycles, which works out to roughly 7 to 10 years for an average household opening the door three or four times a day. Use it more often, like a busy family coming and going all day, and you might see 4 to 6 years. High-cycle springs rated for 20,000 or more cycles are available if you want them to last longer.
Why did my spring break in winter?
Cold weather is hard on springs. Metal contracts and becomes more brittle in freezing temperatures, so a spring that was already near the end of its cycle life often gives out on the first really cold morning. It's one of the most common times of year for spring failures, so a winter break doesn't mean anything was installed wrong, the timing just lined up.
