Why Is My Garage Door Stuck Halfway?
A door stopped part-way is under uneven load. Keep people and cars clear, stop pressing the button, and work out which way it was moving.
Quick Answer
A garage door that stops halfway has usually hit something in the track, lost a cable on one side, or run out of spring support so the opener cannot carry the weight. Opener settings and blocked safety beams can also stop it part-way. Look at the door from inside: if it hangs crooked or a cable is slack, a cable or drum has failed. If it is level but stuck, check the tracks for a bent section, a broken roller or sand build-up. Do not walk under it, and do not pull the release cord while it is open, because a door without spring support can drop.
Likely Causes
Cable off the drum or snapped
The commonest reason a door hangs on one side. One end lifts, the other drags, and the door jams in the track.
Bent track or broken roller
A knock from a car or a bin can kink the track. A cracked roller can catch and stop the door mid-travel.
Weak or broken spring
Without full spring support the opener senses too much weight and stops. You may hear the motor strain before it gives up.
Safety beams or force setting
If the door stops and reverses, the beams may be blocked or misaligned, or the opener's force setting may need adjusting.
Sand and grit in the tracks
On sandy blocks, sand collects in the bottom of the tracks and stiffens the rollers until the door binds.
Checks You Can Do Without Risk
Fine to check yourself
- Note whether the door stopped going up or coming down
- Look from inside to see if the door is level or hanging on one side
- Check the safety beam lenses are clean, aligned and unobstructed
- Look along each track for a dent, a gap or a roller out of place
- See whether anything is caught in the track or under the bottom edge
Leave these alone
- Do not walk or drive under a door that is stuck part-way
- Do not pull the release cord while the door is open
- Do not keep running the opener to force it free
- Do not hammer the track or lever the door with a bar
- Do not touch cables, drums or springs
Signs It Needs a Technician
If you notice any of these, stop using the door and ring us to talk it through.
- The door is hanging lower on one side
- A cable is slack, frayed or off its drum
- Rollers have come out of the track
- The door stopped after a loud bang
- It will not move in either direction with the opener

Frequently Asked Questions
It depends on what jammed it. Sand in the track can be cleaned out, and a blocked safety beam realigned. A cable off its drum, a bent track or a broken spring needs the door supported and the tension controlled, which is a technician's job.
Very little safely. A door hanging on one side almost always has a cable that has slipped or snapped. Switch the opener off, keep clear, and leave the door where it is. Moving it can pull the other cable off as well.
On a sectional door, a bowed middle usually means a panel or its strut has bent, often because the opener kept pushing against a jam. It weakens the door and can bind the rollers. Stop using it until it has been checked.
That is the opener's safety reverse. Something has crossed the safety beams, the beams are out of line, or the door is meeting resistance the force setting reads as an obstruction. Clean and align the beams first.
No. A door that has stopped part-way may be held only by one cable or a weakened spring. Leave the car where it is and call us. Once the door is supported and repaired, you can get out safely.
