Garage Door Torsion Spring Snapped - What to Do Before the Tech Arrives

You heard the bang. Or you didn't hear it but the door stopped working and now you see a gap in the spring above the door. Either way the spring is broken and you've called for service. Tech is on the way.

Here's what to actually do in the meantime - and just as importantly, what not to do.

Stop pressing the opener button right now

This is the most important thing and people keep doing it anyway because pressing the button is the instinctive response when something isn't working.

Without the spring, the door weighs whatever the door weighs - 130 to 300 pounds - with no counterbalance. The opener tries to lift that. It hums, it strains, it might get the door a couple inches off the ground, then the force protection kicks in. Motor off. Nothing happens.

Pressing it again does the same thing. And again. Each attempt heats up the motor. Run it enough times and you trip the thermal protection and potentially damage the motor permanently. What was a spring problem becomes a spring plus burned out opener problem.

Two or three presses to confirm it's not working - reasonable. After that, stop. Wait for the tech.

Don't try to force the door open manually by yourself

The door can be opened manually - that's what the emergency release cord is for. But without the spring counterbalancing the weight, you're lifting the full door weight yourself.

For a typical single-car door that's 150 pounds, that's a significant lift. For a heavy double-car door at 250-300 pounds, that's not something most people should attempt alone.

If you absolutely need the car out before the tech arrives - get a second person. Two people, one on each side, lift slowly and evenly. Get the car out. Lower the door back down carefully. Don't try to hold it propped open - lower it back to the floor once the car is clear.

Then don't use the door again until the spring is fixed. If the car is out, leave it out until after the repair.

Look at the spring but don't touch it

Look up at the spring above the door. You should see the break - a gap somewhere in the coil, the spring in two sections where it used to be continuous.

If it's a two-spring setup, look at both springs. Is just one broken or both?

This information is useful when you talk to the tech. "One spring broke, the other looks intact" tells them what they're walking into. "Both springs broke" is rarer but it happens and they need to know.

Don't touch the spring itself. Don't try to push the two pieces back together. A broken torsion spring still has stored tension in it - the section still wound to the bar has energy in it. Leave it alone.

Check for anything secondary that might have happened

Sometimes when a spring breaks suddenly, other things happen too. The rapid loss of tension can cause a cable to come off its drum. The door might have lurched if it was mid-travel when the spring went.

Look at the cables on both sides - should be running taut from the bottom corners up toward the drums. If one is hanging loose or piled on the floor, the cable came off the drum. Mention this to the tech when they call. Doesn't change the urgency but it tells them what parts and how much time to plan for.

Look at whether the door itself is sitting evenly. Is one corner lower than the other? Is the door tilted or crooked? If it is - don't operate it in any way until the tech arrives.

What to actually tell the tech when they call

Most service companies call before arriving to get information. Having clear answers saves time and means they show up with the right parts.

Tell them: single-car or double-car door. Single torsion spring or double torsion spring setup (one spring on the bar or two). Whether one or both springs appear broken. Whether any cables look loose. Whether the door was in motion or at rest when it broke.

If you want high-cycle springs - mention it on the call. If they need to bring different parts, better to know before they're on the way.

Prepare the workspace for the tech

Clear the area under and around the door. Move cars out of the way if they're not stuck. Move anything stored directly in front of the door that could interfere with the tech working.

Spring replacement requires working on a ladder near the door and reaching the spring bar above the door. The tech needs clear access to both sides of the door and to the space below the spring bar.

If the garage is cluttered directly in front of the door - 10 minutes of moving things now saves time and potentially cost.

What happens when they arrive

Tech assesses the spring - confirms what broke, checks the cable drums and cables, looks at the overall condition of the door hardware while they're at it.

If it's a single spring replacement, they'll replace it and very likely recommend doing the second spring too if it's a two-spring setup. Standard advice and correct advice - explained in another post if you want the full reasoning.

Spring comes off, new spring goes on, gets wound to the correct tension for your door's weight. This is the part that takes experience and proper tools - winding torsion springs uses specific winding bars and knowing the correct number of turns. Not something to watch and try yourself later.

Door gets balanced - disconnected from the opener, lifted to waist height, released to confirm it holds. Opener reconnected and tested. Done.

Usually 30-45 minutes for a tech who does this regularly.

After the repair - before you send them on their way

Test the balance yourself. Pull the cord, lift to waist height, let go. Holds in place or drifts very slightly - good. Drops - tension isn't right, tell them before they pack up.

Test the auto-reverse. Put a 2x4 flat on the ground, close the door, confirm it reverses on contact. A new spring doesn't change force settings but it changes how the door behaves, so worth confirming.

Run the door through a few full cycles and listen. Should sound more relaxed than before the spring broke - opener not straining, smooth travel.

If anything seems off - mention it right then. Getting a callback handled while the tech is still there is much easier than scheduling a return visit.

If the tech can't come until tomorrow

Sometimes same-day service isn't available. You need to manage overnight with a broken spring.

If the door is closed and the car is inside - the car stays inside until the repair. The door can be opened manually with a second person's help if absolutely necessary, but if you can wait, wait. Moving the car out and back in on a broken spring adds risk and puts wear on hardware that's already stressed.

If the door is stuck open - this is the more urgent situation. A garage that can't be closed is a security problem. Call the service company and specifically mention the door is stuck in the open position. Most companies will prioritize this. If they can't come today, ask if they can at least advise on safely getting the door to the closed position manually so the garage is secure overnight.

Never leave a door stuck open overnight if you can avoid it. Whatever is in the garage is exposed.

Questions worth asking the tech before they leave

What cycle rating are the springs they installed? Standard 10,000-cycle or high-cycle?

Were the cables and drums inspected and found to be in good shape?

Is the spring balance correct - both doors hold at waist height?

Is there anything else they noticed while they were in there that should be addressed?

A tech who's doing good work has no problem answering all of these. If they're evasive about spring ratings or skip the balance test - that's a flag.
