What’s Happening
A garage door that won’t open almost always comes down to one of four things: a broken torsion spring, a snapped or jumped cable, a dead or malfunctioning opener, or a door that has physically bound up in its tracks. In most cases, a trained technician can identify the cause in under ten minutes and have the door running the same visit.
The tricky part is that these four causes can look nearly identical from where you’re standing – the door just doesn’t move. But each one has a tell. A spring failure usually makes a loud bang, like a shotgun going off in the garage. A cable problem often leaves the door hanging at an angle or sitting lower on one side. An opener issue is quieter – you press the button, the motor hums or clicks, but nothing happens. A binding track usually grinds or stutters before stopping altogether. Paying attention to what you heard, and what you’re seeing right now, will help us get to the root of it faster when we arrive.
Why It Happens
Broken Torsion Spring
The torsion spring is the part Mainspring Garage Door Co. is literally named after – it carries the full weight of your door every single time it moves. Most springs are rated for a set number of cycles, and once that count is up, they break. When one snaps, you’ll often hear a sharp bang from inside the garage. Look above the door’s horizontal rail for the spring mounted on a metal bar; if you see a visible gap or separation anywhere along the coil, that’s your answer.
Safety note: Do not attempt to operate the door manually or touch the spring hardware. A loaded torsion spring holds enormous tension and can cause serious injury if handled without proper training and tools. Stop here and call a professional.
Broken or Jumped Cable
The lift cables run from the bottom corners of the door up through a pulley system, and they work alongside the spring to keep the door balanced. A snapped cable often drops one side of the door lower than the other, so the door looks crooked or tilted in the opening. A cable that has simply slipped off its drum produces a similar effect. Either way, the door will feel dramatically heavier on one side if you try the manual release.
Safety note: Like springs, cables are under significant tension and are connected directly to spring hardware. Do not try to reattach or rewind a cable yourself.
Opener Motor or Logic Board Failure
If you press the wall button and hear the motor run but the door doesn’t move, the drive system – whether chain, belt, or screw – may have disconnected or stripped. If nothing happens at all, no sound, no light, the logic board or power supply is the likely culprit. Check that the opener is still plugged in and that the outlet has power. Try the wall button instead of your remote, since dead remote batteries mimic a dead opener. If neither works and power is confirmed, the unit likely needs a technician.
Door Off Track or Binding
Tracks can bend from an accidental bump with a car, from decades of vibration, or simply from a roller that finally gave out. When a roller pops out of the track, the door may move an inch or two and then stop hard. You’ll often hear a grinding or scraping sound. Look at the vertical tracks on both sides while the door is in its lowest position – bent metal, gaps between the roller and track, or visible rollers hanging outside the channel are all signs the door has come off its guide.
What to Do Right Now
- Stop using the opener. Forcing a door that won’t move can damage the opener drive, bend the tracks further, or create a safety hazard if a spring or cable is already compromised. Press nothing else until you know what you’re dealing with.
- Look and listen before you touch anything. Stand a few feet back and look at the door from the front. Is it level or tilted? Is there visible damage to the tracks? Look through the garage window at the spring bar above the door if you can – a gap in the spring coil is a clear sign of a break. Do not enter the garage yet if you suspect a spring failure.
- Check your opener’s power. If the motor is silent, confirm the opener is plugged in and that the circuit breaker hasn’t tripped. Try the wall-mounted button separately from your remote. If a fresh battery in the remote fixes it, that’s your answer and you’re done.
- Take a photograph. A photo of the spring bar, the cables at the bottom corners, and the track on each side takes thirty seconds and helps our technician arrive knowing what to expect. Text it or keep it ready to show on arrival.
- Use the manual release only if it’s safe to do so – and only to exit the garage if needed. The red cord hanging from the opener trolley disconnects the door from the drive system. Pull it straight back, not at an angle, and only if the door appears level and undamaged. If the spring is broken, the door will be extremely heavy without the spring’s counterbalance – do not attempt to lift it alone.
How We Fix It
When your local Mainspring Garage Door Co. technician arrives, the first thing that happens is a full diagnostic – springs, cables, tracks, rollers, opener, and safety sensors all get checked, not just the part that looks broken. We’ve seen too many jobs where one broken spring was hiding a second spring that was days from going. Once we know what we’re dealing with, we’ll give you a flat price in writing before any work begins. No surprises on the bill.
Because our trucks are stocked with torsion springs in common sizes, cables, rollers, and the major opener brands – LiftMaster, Chamberlain, Genie, Craftsman, and others – most repairs are finished in a single visit. A spring replacement typically takes about an hour. A cable repair is similar. If the opener needs replacing, we’ll walk you through the options and swap it the same day in most cases.
Every completed job is covered by our 90-Day Done Right Promise: if something isn’t right after we leave, we come back and make it right – in writing, no arguing, no paperwork battle. That’s been our standard since 1984, and it still is.
The relevant services for a door that won’t open are Garage Door Repair and, when the opener is the root cause, Garage Door Opener service. If you’re dealing with a middle-of-the-night failure, our Emergency Garage Door line is answered by a live person around the clock – not a machine, not an answering service.
Frequently Asked Questions
It depends on what caused it. A broken spring or snapped cable means the door is under uneven or zero tension, which makes it genuinely dangerous to operate manually – and in some cases to even be near without knowing the full condition. A dead opener battery is not dangerous at all. If you heard a loud bang, if the door is visibly tilted, or if a cable appears to be hanging loose, treat it as urgent and don’t use the door. Call (844) 755-5838 and a live person will help you assess it right now.
Our phones are answered by a live person 24 hours a day, seven days a week, including holidays – so you can reach us the moment the problem happens. Your local Mainspring team will tell you honestly what availability looks like and get a technician to you as quickly as the schedule allows. Call (844) 755-5838 and we’ll get it sorted.
Most of the time, repair is the right answer – especially when the door itself is structurally sound and only one component has failed. A broken spring or bad opener on an otherwise solid door doesn’t justify a full replacement. The technician will look at the overall condition of the door and hardware on arrival and give you an honest read. If replacement makes more sense, we’ll tell you why and give you that quote in writing too, before anything is decided.
We don’t quote prices before a technician has actually seen the door, because the right number depends on which spring size is needed, whether cables went with it, the condition of the rollers, and what opener model may be involved. What we can tell you is that we’ll hand you a written flat price before the first bolt is turned – and that price is what you pay. If you have a written estimate from another company, we’ll give you a free second opinion on it. Call (844) 755-5838 to get the process started.
