That loud snap you just heard was almost certainly a broken torsion spring, and that's why your garage door suddenly feels like it weighs 300 pounds. Don't try to force it open. The spring is the part that counterbalances the weight of the door, and once it breaks, the door becomes genuinely dangerous to operate. Broken torsion springs are the single most common emergency call our team handles across the Philadelphia area and South Jersey, and in nearly every case the fix is a same-day broken garage door spring replacement.
What does a breaking garage door spring sound like?
A breaking torsion spring sounds like a gunshot, a firework, or a loud metallic bang coming from inside the garage. Most Philly homeowners who hear it think something fell off a shelf or a car backfired on the street. The sound is sharp, loud, and unmistakable, and it usually happens when the door is at rest, either fully closed overnight or first thing in the morning when you hit the opener.
The reason it's so loud is that a torsion spring stores a huge amount of rotational energy. When the metal finally fatigues and fractures, that energy releases instantly in a fraction of a second. It's almost always loud enough to wake you up from a dead sleep, and neighbors in row homes from South Philly to Collingswood have called us after hearing the bang through a shared wall. Our technicians have responded to thousands of these calls across Philadelphia, the Main Line, Bucks County, and South Jersey, and the description homeowners give us is remarkably consistent: "It sounded like a shotgun went off in the garage."
What does a broken torsion spring look like?
A broken torsion spring has a visible gap of two to four inches in the middle of the spring coil, right on the bar above your garage door. Walk into the garage, look up above the door, and you'll see the spring wound tightly around a long metal shaft. If it's broken, you'll see one spot where the coils are pulled apart and the spring looks like it's been cut in half.
Some doors have one spring, and some have two. If yours has two springs and only one looks broken, you'll still want both replaced at the same time. The unbroken spring is almost certainly the same age and has the same amount of wear, so it's usually only weeks or months away from snapping too. Paying for one service call instead of two is the right move nearly every time.
Why does the door suddenly feel impossibly heavy?
Your garage door feels impossibly heavy because it actually is impossibly heavy without the spring doing its job. A standard 16-foot insulated double door weighs around 200 to 250 pounds, and a solid wood carriage-style door can easily exceed 400 pounds. The torsion spring is what makes that weight feel manageable, whether you're lifting by hand or letting the opener do the work.
When the spring breaks, all of that weight transfers directly onto whatever is trying to lift the door. If you hit the opener button, you'll usually hear the motor grind, strain, or buzz, and the door might lift an inch or two before giving up, or it might not move at all. Some openers have an internal gear that strips under this kind of load, which turns a quick spring repair into a additional opener replacement. This is why stopping immediately after the snap is so important.
Could it be something other than a broken spring?
A loud snap followed by a door that won't open is almost always a torsion spring, but there are two other possibilities worth mentioning. A broken lift cable can make a similar sharp sound, and if a cable snaps, the door will often look crooked or hang lower on one side. A snapped cable usually also leaves the cable itself visibly dangling or coiled on the floor next to the door. If that's what you're seeing, you need cable repair rather than spring replacement, though the safety advice is identical: don't touch it, don't force it.
The second possibility is an extension spring, which sits along the horizontal tracks on either side of the door rather than above it. Extension springs are less common in the Philadelphia area than torsion springs, but we see them in older homes and garages with lower ceilings. A broken extension spring usually leaves the door hanging unevenly, with one side dropping lower than the other.
What should you do right now?
Stop using the opener, leave the door where it is, and do not try to manually lift it. Pulling the red emergency release cord will not help in this situation. That cord disconnects the door from the opener, but the door still needs the spring to be liftable by hand. Disconnecting the opener on a broken-spring door can actually make things worse, because the door can slam down with full weight if it's partially raised.
If your car is trapped inside, two people can sometimes lift the door enough to get it out, but this is genuinely risky and we don't recommend it. Cable ends, drum shafts, and the broken spring itself can all cause serious injuries, and a door that slips mid-lift can crush a hand or a foot. The better call is to leave it alone and schedule emergency service.
