It always seems to happen at the worst time. You’re running late, you press the button, and the garage door doesn’t move, or it lifts a few inches and stops. Your car is on one side, and your day is on the other.
The good news is that many garage door failures have simple causes you can check in a few minutes. The important news is that some don’t, and trying to force a door with a broken part can turn an inconvenience into an injury.
Here’s how to figure out what’s going on, what you can safely try, and when it’s time to call for help.
First, Stay Safe
Before you start troubleshooting, a few things to avoid:
- Don’t keep pressing the button. If the opener is straining against a stuck or broken door, running it again can burn out the motor, strip its gears or pull the door off its tracks.
- Don’t force the door up by hand if it feels extremely heavy. That usually means a broken spring, and you’d be lifting the door’s full weight.
- Don’t touch springs, cables or the bottom brackets. They’re under heavy tension, even when something is broken.
- Don’t drive into or through a door that’s partly open or hanging crooked. It can fall or come off its tracks.
- Keep kids and pets out of the garage until the door is fixed.
If you heard a loud bang from the garage before the door stopped working, skip ahead. A spring has likely broken.
Start With the Easy Stuff
Many “broken” garage doors turn out to have a simple fix. Run through these first:
| Check | What to look for | What to try |
| Power | Opener lights don’t come on, or the wall button does nothing | Make sure the opener is plugged in, check for a tripped breaker or GFCI outlet, and reset it |
| Remote | The wall button works but the remote doesn’t | Replace the remote’s battery, or reprogram it |
| Lock mode | The wall console shows a lock or vacation mode, or remotes stopped working all at once | Turn off the lock or vacation mode on the wall console |
| Manual lock | The door has a slide bolt or handle lock that’s engaged | Unlock it. An opener can’t lift a locked door |
| Safety sensors | The door starts to close and reverses, or the opener lights blink | Wipe the lenses, clear anything in the beam, and realign the sensors until both indicator lights are steady |
| Disconnected trolley | The motor runs but the door doesn’t move | The emergency release may have been pulled; reconnect the trolley per your opener’s manual |
If one of these solves it, great. If the door still won’t move, or if you notice anything from the next section, stop and call a pro.
Signs It’s a Mechanical Problem
If the easy fixes don’t help, look, without touching, for these signs:
- A broken spring. Look at the springs above the door or along the ceiling tracks. A torsion spring with a visible gap of an inch or two has snapped. The opener may hum or lift the door only a few inches before stopping.
- A loose or broken cable. Look at the bottom corners of the door. A cable hanging loose, frayed or off its drum often leaves the door crooked or stuck.
- A door off its track. Rollers that have popped out of the track, or a door that’s tilted or jammed, usually point to a bent track, a broken cable or a bump from a car.
- An opener problem. If the motor makes no sound, or hums or clicks but doesn’t move a door that’s otherwise balanced, the opener itself may have failed.
All of these need a technician. Springs, cables and track problems involve heavy tension and a door that may be unstable, and they’re among the most dangerous parts of a garage door to repair.
Opening the Door by Hand, Only If It’s Safe
If the problem is with the opener or the power, and the springs, cables and tracks all look fine, you can usually open the door manually:
- Make sure the door is fully closed. Pulling the release with the door open can let it slam down if a spring is weak.
- Pull the emergency release cord, usually a red handle hanging from the opener’s trolley. Pull it down and toward the door.
- Lift the door slowly by hand, using the handles or the bottom section. A balanced door should rise fairly easily.
- Stop if it feels very heavy, binds or tilts. That’s a sign of a spring, cable or track problem. Lower it gently and call for help.
- Hold the door open. If it won’t stay up on its own, have someone steady it, or clamp locking pliers on the track just below a roller to keep it from coming down, then back the car out carefully.
- Close it and reconnect the trolley once the opener is fixed, following your opener’s instructions.
If the door won’t open safely, it’s better to leave the car where it is and call for service. Many garage door companies treat a car trapped inside as a priority call.
When to Call, and How to Avoid a Repeat
Call a garage door technician right away if a spring or cable is broken, the door is off its track or hanging crooked, the door won’t stay up when opened by hand, or nothing on the quick-check list solves the problem. When you call, mention whether your car is trapped, what you heard and saw, and whether the door is open, closed or stuck partway. It helps the technician come prepared with the right parts.
Most emergency calls can be prevented with a little routine care:
- Watch and listen. New grinding, jerking or sluggish movement are early warnings.
- Lubricate twice a year. A garage-door spray on hinges, rollers and springs keeps things moving freely.
- Test the balance and auto-reverse a few times a year.
- Schedule an annual tune-up, where a technician can catch worn springs, frayed cables and loose hardware before they fail.
- Consider battery backup on your opener, so a power outage doesn’t trap your car.
A garage door that’s cared for is far less likely to leave you stuck. And when something does break, knowing what to check, and what to leave alone, makes the morning a lot less stressful.
