AfterGarage Door Won’t Open: What It Means and How to Fix It
A garage door that won’t open is almost always caused by a broken spring, a snapped or slack cable, or a dead/disconnected opener – and in most cases, a technician can diagnose and fix the problem in a single visit. If you heard a loud bang before the door stopped working, a spring is the likely culprit. If the door feels heavier than usual or hangs crooked, a cable is probably the issue.
The good news is that none of these failures mean the door is totaled. They mean one component – sometimes two – needs to be replaced by someone who knows what they’re handling. Springs and cables are under serious mechanical tension, so this is not a repair to improvise. Below is a plain-language breakdown of what’s going wrong, what you can check safely, and what happens when your local Marlow Garage Door Repair team shows up.
Why It Happens
1. A Broken Torsion or Extension Spring
Springs do most of the heavy lifting – literally. They counterbalance the door’s weight so the opener motor doesn’t have to carry it alone. When a spring breaks, the opener runs but the door barely moves, or doesn’t move at all. The clearest sign is a loud bang from the garage (people often mistake it for something falling), followed by a door that either won’t budge or only lifts a few inches. Look above the door: if you see a torsion spring with a visible gap in the coil, that’s your answer.
Safety note: Do not try to open the door manually more than a few inches, and do not attempt to handle the spring yourself. A torsion spring stores enough energy to cause a serious injury. Stop, step back, and call.
2. A Snapped or Slack Cable
Cables run alongside the springs and help guide the door evenly up and down the tracks. When one snaps or slips off its drum, the door may open partially on one side and stick, or it may hang at an angle. You might see a coil of cable lying on the garage floor near the bottom corner of the door. A door that looks tilted when it tries to open is a strong cable signal.
Safety note: Like springs, cables are under significant tension even when they appear slack. Don’t pull on them or try to rewind them. Photograph what you see and wait for the technician.
3. A Dead, Disconnected, or Struggling Opener
If you press the wall button or remote and hear nothing at all – no motor hum, no click – the opener may have lost power or tripped a circuit. Check whether the unit’s indicator light is on. If the opener hums but the door doesn’t move, it may be running without being connected to the door (the manual-release cord sometimes gets pulled accidentally, disconnecting the carriage). If the opener is a LiftMaster, Chamberlain, Genie, or Craftsman unit and the door was working fine until recently, start here before assuming a spring or cable is gone.
4. Bent Track or Blocked Rollers
Sometimes the door itself is fine but the track it rides in is bent, or a roller has jumped the track. This usually sounds like grinding or scraping rather than a bang, and you can often see the problem by looking at the vertical track on either side of the door. A visible kink in the metal, or a roller sitting outside the track channel, points to this cause. The door will typically stop moving mid-travel rather than refusing to start at all.
What to Do Right Now
- Stop using the opener. Forcing a door that’s jammed by a broken spring or cable can damage the opener motor, bend the track, or – in the case of a half-attached door – cause it to fall. One press to confirm it won’t open is enough.
- Do not manually lift the door if you suspect a spring is broken. Without a functioning spring, a double-car door can weigh 150 to 200 pounds. You can’t hold it safely, and it can come down fast.
- Check the obvious first. Is the opener plugged in? Is the wall outlet working? Has someone pulled the red manual-release cord? These take 30 seconds to rule out and occasionally solve the whole problem.
- Look, don’t touch. Walk along the track and look at the springs, cables, and rollers from a safe distance. Take photos on your phone – they help the technician arrive with the right parts.
- Call your local Marlow Garage Door Repair team. A live person answers at (512) 883-4374 around the clock, every day of the year. Tell them what you heard and what you see, and they’ll tell you exactly what’s coming and when.
How We Fix It
When your local Marlow technician arrives, the first thing they do is a full visual diagnosis – springs, cables, tracks, rollers, and opener – before touching anything. You get a written price for the exact repair needed before any work begins. That number doesn’t change once they start. If the issue is a broken spring, that falls under our Garage Door Spring Repair service. Snapped or derailed cables are handled under Garage Door Cable Repair. Many calls involve both, since a failed spring often takes a cable with it, and the tech arrives stocked for the most common combinations on the eight brands we service: LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor. Most spring and cable repairs are complete within an hour or two. Every repair is covered by the 365-Day Done Right Promise – if something isn’t right within a year of the visit, we come back and make it right. That’s in writing, not buried in a footnote.
Frequently Asked Questions
Yes, depending on the cause. A door held in place by a broken spring is under unpredictable stress and can drop without warning if disturbed. Beyond the physical risk, a door stuck open or only partially closed is a security problem. Don’t leave it sitting open overnight or assume it’s stable just because it stopped moving. Call (512) 883-4374 and get a technician out the same day.
Your local Marlow team handles repair calls – spring repairs, cable repairs, and general garage door repairs – as priority same-day service. Call (512) 883-4374 and a live person will answer right now, any hour, any day. They’ll give you a live arrival time you can track before the tech even leaves, so there’s no four-hour window to sit through.
No. The written price is agreed before any work starts – that’s a non-negotiable standard on every Marlow job, not a policy we apply selectively. The number on the invoice matches the number you approved. If the technician finds something additional during the repair, they’ll stop, explain it, and give you a new written price for the new scope before proceeding.
You can safely check power, inspect the opener connection, and photograph the components – that’s useful and we encourage it. But broken springs and snapped cables are a different matter. They are under significant mechanical tension even when the door isn’t moving, and releasing that tension incorrectly can cause a serious injury. The repair requires specific tools, replacement parts matched to your door’s weight, and hands-on experience. The free written estimate costs nothing, and you’ll know the exact price before committing to anything. Call (512) 883-4374.
