Wolf Garage Door Services teamA door stuck partway open is a security problem and, depending on the cause, a safety one. The good news: a few of the most common reasons are easy to check from the floor.
Work through the list below in order. If you reach a sign of a mechanical failure, stop there.
Quick checks you can do safely
- Look for an obstruction. A rake handle, bike tire or storage bin can catch the door or block the bottom edge.
- Check the photo eyes. The two small sensors near the floor on each side of the opening should have steady lights. A blinking light means they are blocked, dirty or knocked out of line. Wipe the lenses and nudge them back so they face each other.
- Check the manual lock bar. Many doors have a slide lock on the inside of a section. If it is engaged, the opener strains and stops.
- Look at the wall control. A lock or vacation mode can disable remotes, which sometimes looks like a stuck door.
- Try the wall button once. If the opener hums but nothing moves, stop pressing it.
The red release cord: use it with care
The red cord disconnects the door from the opener. If the spring or a cable has failed, the opener is the only thing holding the door up. Pull the cord and the full weight of the door can drop.
Look up at the spring above the door before touching the cord. A gap in the coil means a broken spring. If you see one, don't pull the release; keep everyone clear and phone a technician.
When it is off track, a spring or a cable
| What you see | Likely cause |
|---|---|
| Rollers sitting outside the track, door crooked | Off-track door |
| A visible gap in the coil above the door | Broken torsion spring |
| One side lower than the other, slack wire | Snapped or slipped cable |
| Door bowed or a section bent inward | Door forced against a jam |
| Opener runs, trolley moves, door doesn't | Disconnected or failed opener carriage |
Each of these involves parts under heavy load. See our pages on off-track repair and spring repair for what the fix involves.
What not to do
- Don't keep pressing the remote. Each try puts more strain on a bent track or a twisted section.
- Don't hammer a roller back into the track with the door hanging. It can drop or swing out.
- Don't stand or let kids play under a door that is stuck open.
- Don't loosen track bolts or spring hardware.
- Don't tie the door up with rope or a strap and leave it overnight.
Getting it fixed
A door stuck open at 10 PM is exactly the kind of call we take. Our lines are answered 24/7. The technician inspects the whole door first, explains what failed and why, and gives you the price before starting.
Frequently asked questions
Why does my garage door go up a little and then stop?
The opener has a safety limit on how hard it will pull. If a spring is broken, a roller is binding or the door is locked, the opener senses too much resistance and stops. That is the opener doing its job, not the cause of the problem.
Can I close a garage door stuck halfway by hand?
Only if the spring and both cables are intact and the door is still in its tracks. If anything looks broken, leave it. A door without spring support can weigh more than a person can safely control.
Is an off-track door an emergency?
It can be. A door hanging partly out of its track can fall. Keep everyone away from it, don't run the opener, and get a technician to secure it.
