Short answer
A garage door that does not move at all is almost always disconnected from the opener or held by a broken spring. Press the wall button and listen. If the motor runs and the door stays put, the trolley has come off the door arm, usually after someone pulled the red emergency release handle. If the opener is silent, check the plug, the breaker and the lock button on the wall control. If the door is dead weight when you lift it by hand, a spring is broken, and that one is a hire.
Tell a disconnected door from a broken spring in five minutes
- Press the wall button and listen. Note whether the motor hums or runs, clicks once, or makes no sound at all.
- Watch the trolley on the rail overhead. If it slides along the rail while the door stands still, the door arm is unhooked from the trolley.
- Look for the red handle hanging from the trolley. A pulled handle leaves the door in manual mode until the trolley re-latches.
- Check power if the opener is silent. Confirm the unit is plugged in, the ceiling outlet works with another device, and the breaker is on.
- Press and hold the lock button on the wall control for a few seconds. Lock mode kills the remotes and is easy to switch on by accident.
- Look at the spring above the door or along the track. A finger-width gap in a coiled torsion spring means it is snapped.
- Lift the door by hand only with the opener unplugged, and only a few inches. A balanced door rises easily and holds where you leave it.
If the trolley re-latches and the door runs, you are done. If the door is dead weight by hand, or you see a gap in the spring, stop there and hire a garage door tech. Springs hold enough tension to break bones.
Repair or replace
| Situation | What to do |
|---|---|
| Motor runs, door stays put, red handle was pulled | Repair. Pull the door fully closed, then run the opener until the trolley snaps back onto the arm. |
| Opener silent, outlet dead or breaker off | Repair. Restore power at the breaker and test the ceiling outlet before anyone sells you a part. |
| Opener silent, remotes dead, wall control still works | Repair. Lock mode or a failed receiver board. A tech tests both on the trip. |
| Gap in the torsion spring, door is dead weight by hand | Repair, but hire for this. Springs get replaced in pairs by a tech with winding bars. |
| Opener over 15 years old and unresponsive, door panels sound | Replace the opener only. The door, tracks and springs stay. |
| Door dented, rusted or delaminated and the opener is also past 15 years | Replace both. New tracks and springs come with the door, so the labour is paid once. |
What it costs
Runhome contractor estimates for replacing a single-car garage door and opener ran from $1,975 to $5,300 as of October 2026, including the trip and assessment.
| Option | Range |
|---|---|
| New insulated steel door and opener, installed | $1,975 to $5,300 |
Can I do it myself?
Yes, for the two cheapest causes. Re-latching the trolley takes one person and no tools: close the door fully by hand, then hold the wall button until the carriage slides back over the arm and clicks. Restoring power at the breaker and clearing lock mode on the wall control are also homeowner jobs.
Hire someone the moment springs, cables or the opener's wiring are involved. A torsion spring stores enough force to throw a winding bar across the garage, and a lift cable under tension cuts. Hire for this.
What a contractor will ask you
Have these ready and you skip the back-and-forth.
- Whether the door itself moves at all, or stays in one place.
- What you hear at the wall button: humming, a single click, motor noise, or nothing.
- Whether the red emergency release handle has been pulled, by you or anyone else.
- Single-car width or double-wide.
- The age of the opener unit, as close as you can guess.
- The door material, and whether the panels are flat and smooth or look like painted wood with grain.
- Whether the top section has windows.
- Whether the garage is attached to the house or fully detached.
- Whether you want the existing door and opener repaired, or the whole door and opener replaced.
- A wide photo of the entire door and the surrounding wall, floor to header and side to side.
Common questions
- My garage door opener runs but the door doesn't move.
The trolley on the rail is no longer connected to the arm on the door. That happens after the red emergency release handle gets pulled. Close the door by hand, then run the opener until the trolley snaps back on.
- I pulled the red handle and now the door won't open with the remote.
The handle switched the door to manual on purpose, and it stays that way until the trolley re-latches. Pull the door all the way down first, because re-latching a half-open door lets it drop. Then hold the wall button until you hear the click.
- Can I open the garage door by hand if the spring is broken?
No, and do not keep trying. A single-car door weighs 130 pounds or more, and the spring is what carries that weight. Leave it closed and hire a garage door tech.
- Is it worth replacing the opener instead of the whole door?
Yes, when the door panels, tracks and springs are sound and only the opener has died. A new opener on a good door is the cheaper half of the job. Replace both only when the door is dented, rusted or no longer balanced.
- Why does my garage door move an inch and then stop?
The opener is hitting resistance and reversing on its safety setting. Look for a bent track, a seized roller, or ice bonding the bottom seal to the slab. Clear the obstruction before you touch the force adjustment.
