Garage Door Broken? What Is Actually Wrong, and What to Do Right Now

Published October 12, 2026

"Broken" nearly always means one of six things: a snapped spring, a snapped or slipped cable, a door that has jumped its track, an opener that runs but does not move the door, photo-eye sensors that stop it closing, or worn rollers making it grind. What you heard and what you see narrows it to one or two of those before anyone touches the door. The one rule that matters right now: stop pressing the button. An opener pushing against a door that cannot move is how a small repair becomes a large one.

Start with what you heard and what you can see

A loud bang from the garage, often mistaken for a gunshot or something falling, followed by a door that will not open or lifts a few inches and stops: that is a broken spring. Look above the door. On a conventional system you will see a two-inch gap in the coiled spring. If you cannot see any spring at all, you have an enclosed system and the broken one will not look broken; the door simply feels extremely heavy by hand.

One side of the door hanging lower than the other, a door crooked in the opening or wedged in the track, a loose cable dangling beside it, or a frayed cable with broken strands like a rope coming apart: that is a cable. Rust streaks running down from the bottom bracket often show up first, because road salt eats the bottom of the door before anything else.

The door visibly out of the metal track on one side, jammed at an angle, with a roller lying on the floor or a visible kink in the vertical track: the door is off-track. This usually follows one of three things: a vehicle tapped it, a cable let go, or a worn roller finally came out of the channel.

The opener hums or runs but the door does not move, or there is a grinding noise from the motor unit with no movement: that is inside the opener, most often a stripped drive gear. The door closing partway, reversing, and the opener light flashing: that is the photo-eye sensors at the bottom of the tracks, misaligned, dirty or with a broken wire. The remote working close up but not from the driveway is a battery, an antenna wire or interference, not a broken door at all.

A door that has become much louder than it used to be, grinding, squealing or rattling as it travels, with black dust or metal shavings below the track: rollers. A door that reverses right at the floor and immediately opens again: usually opener travel and force limits that have drifted, or a door that has become genuinely hard to move, so the opener reads it as an obstruction.

What is a repair and what is not

Almost everything above is a repair, usually in one visit. Springs are replaced and re-sized to the door's weight. Cables are replaced in pairs. An off-track door is put back on the track, with the roller or hinge that caused it replaced and the track straightened. Opener gears, logic boards, sensors, trolleys and remotes are all available parts for the brands common around Cincinnati.

Three things honestly point at replacement rather than repair. An opener with no photo-eye sensors at the base of the tracks predates the federal entrapment-protection requirement that took effect on January 1, 1993, and should not be repaired. A bottom section that has rusted through, or several dented or creased sections, usually costs more to patch than a new door. And a very old opener whose board is discontinued is a replacement whatever the brand.

Everything else, including a door that has been "broken" for months and simply hauled up by hand, is normally fixable, and the fix usually costs less than people expect once they stop assuming the whole door is finished.
