Motor runs, door stays put
Garage door opener not working
A motor that runs while the door stays still usually means the drive has failed inside the opener — or that the door has been disconnected from it.
Call 214-733-2371Safe to leave, but check the release cord first
Nothing here is dangerous, but do check the red emergency release cord hanging from the rail — if it's been pulled, reattaching it may be the whole fix. If the door is heavy to lift by hand, that's a spring problem instead, and that one isn't a DIY job.
Likely causes
What’s probably wrong
- 1
Stripped main drive gear
The most common failure in chain-drive openers. A nylon gear wears through and the motor spins without driving the chain. It's a repair, not a replacement.
- 2
Trolley disconnected
If someone pulled the emergency release cord, the door is no longer attached to the opener. Free, thirty-second fix — worth checking before calling.
- 3
Broken chain, belt, or drive sprocket
Less common, and usually audible as a rattle or slap rather than a clean hum.
- 4
Failed capacitor
An opener that hums but won't start under load often has a dead starting capacitor.
