Six heights a door quits at, and what each one means

Why does a door stop part way and stay there?

A door that climbs part way and quits has run into one of three things: something physically in its way, a part that failed under load, or a limit in the opener’s programming. Whichever it is, the door stops where the trouble is, so the height it froze at is most of a diagnosis. You can read it standing in the driveway.

This site has two other guides for doors that never move at all: the one that will not open and the one that will not close. This page is the middle case, the door that moved and then stopped.

One thing before anything else. Quit hitting the button. Every retry drags whatever is jammed a little further out of line, and a door that stopped for a cheap reason can be a bent-track job by the fourth try.

How high was it when it stopped?

Eyeball the height off the floor and remember which way the door was headed. Those two facts sort nearly every mid-travel stop into one of the six below, and each one puts a different part on the truck.

1. At the sensor line, about six inches off the floor, on the way down. The two safety sensors sit at that height, one on each side of the opening. If the door drops to that line and climbs straight back up, the sensors stopped it, and the alignment checks are in the won’t-close guide. If it stops there and stays, look lower for something solid in the threshold: a bag of water-softener salt, a shovel butt, a bike pedal, or ice welded under the bottom seal after a freeze-thaw week.
2. A few inches up, then back down on its own. The opener pulls, gets the door moving, and sets it back on the slab. That is the motor’s overload cutout refusing a weight it was never sized to carry, and the reason the weight changed is a broken torsion spring above the opening. Check the shaft for a gap in the coil about two inches wide. A two-car steel door is 150 pounds or more with no spring helping, so this one is a spring call rather than something to muscle open.
3. Waist to chest height, stopped hard. Cable, roller, and track country. A cable off its drum, a roller out of the rail, or a section of track bent enough to catch. The tell is the top edge of the door: if one corner rides higher than the other, the crooked-door guide reads the cable for you, down to which corner is carrying the load. Stay out from under a door sitting here.
4. Near the top, just short of fully open. Two candidates, and they sound different. A drifted up-limit setting stops the door quietly and cleanly, as though that were the top, often after a power blip or a limit screw that has worked out of adjustment. A worn drive gear gets there and grinds or whirrs instead, because the nylon teeth slip under the last of the load. The grinding version is a gear kit, a stocked repair, not a new opener.
5. The same spot every time, but only on the way down. Momentum carries a door past a rough patch going up and gravity alone does not. Suspect a dent in the vertical track or a cracked roller reaching the same point in its rotation. Dents get there honestly, from the extension ladder that spent February leaning on the rail or the sheet of plywood parked against the track during a basement project.
6. No particular height, with the door shuddering the whole way. Dry rollers and hinges, steel dragging on steel, force climbing until the opener quits wherever it happens to be. Cold mornings make it obvious and a warm afternoon can hide it completely. It usually builds for weeks before it finally strands the door.

Should I pull the red release cord on a door stuck part way up?

No. The cord was built for one situation, a door already sitting fully closed, where disconnecting it from the opener lets you lift by hand and back the car out. Mid-travel is the opposite situation. Once the cord is pulled, the door is hanging on its springs and cables and nothing else, and in several of the six cases above the spring or a cable is the part that already failed. A door that comes down from chest height comes down at full weight.

If a car is walled in behind the door and you have somewhere to be at six, lead with that on the phone. Whether a door can be lifted by hand at all depends on the spring, and that is the first thing the call establishes. When the answer is no, the appointment gets built around your schedule rather than the other way around.

Is a garage door stuck halfway an emergency tonight?

It depends on what the stopped door leaves open. A door hung up with the opening wide and the house behind it exposed overnight qualifies. So does a car walled in before a shift. So does a door off its rail that has not finished moving yet. With the cars out, nothing worth taking in the garage, and nobody needing the opening before morning, a mid-travel door is a next-slot job at the ordinary rate.

Describing it is what sorts those apart, and the sorting call costs nothing at any hour. Emergency garage door repair covers which doors jump the schedule and what the after-hours fee does to the number, which gets quoted whole before a truck moves.

Whatever the answer, do not try to walk the door back onto its rail in the meantime. An off-track door is held where it is by bent metal and pinched rollers, and the shove meant to reseat it is usually the shove that puts the door on the floor.

How much does each of these cost in Hancock County?

Mid-travel stops land across a wide range because the causes do. The pricing page has the full Hancock County list, and these are the lines the six heights map onto:

• Torsion spring replacement (pair): $220 - $400
• Off-track re-hang: $150 - $350, depending on how much track needs straightening
• Cable replacement (pair): $110 - $200, usually bundled into a spring job for little extra
• Opener repair: $120 - $280, covering gear kits, boards, sensors, trolleys, and programming
• Roller replacement (full set): $120 - $240
• Service call and multi-point tune-up: $95 - $150

The shuddering door from the bottom of that list is the one worth calling about before it strands anybody. Dry hardware makes the opener pull harder on every cycle, and the spring underneath is on a clock regardless, since standard springs are rated ~10,000 open-close cycles.

What to do in the hour before the truck arrives

Leave the door at the height it quit at, and keep people and vehicles out of the opening. Then kill power to the opener at the ceiling outlet, because the next person home will try the remote from the driveway without knowing anything is wrong.

Two things are worth doing while you wait. Put a pencil mark or a strip of tape on the jamb at the bottom edge of the door, so you can tell later whether it has crept. And if you can do it without standing under the door, take one photo straight up at the spring shaft.

On the phone, the useful sentences are the height it stopped at, the direction it was going, whether it does this every time or did it once, and whether the two top corners sit level. If you got a look at the coil, say whether it runs continuous or shows a gap. That is enough to load the truck before it leaves for Greenfield, Fortville, or New Palestine. If the door moves on its own while you wait, or you hear something else let go out there, call back at (317) 526-4415 and say so.
