Garage door won’t stay closed - Same-Day Service, Priced Before We Start

Garage Door Won’t Stay Closed

A garage door that reverses before it reaches the floor, stops halfway, or bounces back up almost always has a limit or force adjustment problem, a sensor obstruction, or a mechanical issue with the springs or cables. These are real faults, not glitches, and they won’t fix themselves. The good news is that a trained technician can diagnose the exact cause and tell you in writing what it will cost to correct it before any work begins.

When your door won’t stay closed, the opener is usually doing what it was designed to do: stopping when it thinks something is wrong. The problem is figuring out what “wrong” actually means in your specific case. It could be something simple, like a sensor knocked out of alignment, or something more serious, like a spring that’s lost tension and is causing the door to sit unevenly in the frame. Each cause shows differently, and knowing which one you’re dealing with tells you how urgently you need to act.

Why It Happens

Safety Sensors Out of Alignment

Every opener manufactured after 1993 has two photo-eye sensors mounted near the bottom of the door tracks, one on each side. If those sensors lose their line of sight to each other – because one got bumped, because a spiderweb or dust is coating the lens, or because the mounting bracket shifted – the opener reads it as an obstruction in the doorway and reverses. The telltale sign is a blinking light on the opener motor head, often an amber or green LED on one of the sensors that flickers or stays off entirely. If you see that, the door isn’t broken; it’s doing its job. The sensor is the problem.

Limit Settings Need Adjustment

Limit settings tell the opener how far down the door needs to travel before it’s considered fully closed. If that setting drifts or was never calibrated correctly for your door’s weight and travel distance, the opener will hit its programmed limit before the door actually seals against the floor, then reverse because it thinks it hit a resistance. You’ll usually see the door stop an inch or two above the floor, pause, and then go back up. It looks like obstruction behavior but the sensors are fine.

Spring or Cable Damage

Torsion and extension springs carry the weight of the door. When a spring loses tension or breaks, the door becomes significantly heavier on one or both sides, and the opener struggles to manage the load. The opener’s built-in force sensing will often cut the motor before the door reaches the ground because the resistance triggers its safety mechanism. You might hear grinding, notice the door moving unevenly left to right, or see visible slack or separation in a cable. Do not attempt to operate the door if you suspect a broken spring or frayed cable. These components are under extreme tension and should only be handled by a trained technician.

Track Misalignment or Debris in the Path

If the tracks that guide the door have bent, pulled away from the wall, or collected debris, the door will bind or stop as it travels down. A bent track usually makes a scraping or popping sound at a specific point in the door’s travel – the same spot every time. You can often see a gap between the roller and the track, or a visible kink in the steel. A piece of gravel, a section of peeling weather seal, or even a child’s toy caught in the track can trigger the same response from the opener.

What to Do Right Now

• Check the sensor lights. Walk to the bottom corners of the door and look at both photo-eye sensors. Each should show a solid, steady light – no blinking. If one is out or flickering, something has interrupted the beam. Gently wipe the lens with a dry cloth and see if the light steadies. Do not bend or force the bracket.
• Look for obvious obstructions. Scan the full path of the door, including the floor at the center and edges, for anything that shouldn’t be there: debris, a garden tool, a damaged section of weather seal that’s folded over. Remove anything clearly in the way before trying the door again.
• Listen and watch during operation. If it’s safe to try the opener, run the door once and pay attention to where it stops and what it sounds like. Note the exact point where it reverses – does it stop at the same spot every time, or vary? Does it grind, pop, or move unevenly side to side? That information will help the technician diagnose faster.
• Stop using the door if you see cable or spring damage. If you can see a broken coil, a cable with visible fraying, or a cable hanging loose on one side, stop operating the door immediately. Close it manually only if you can do so safely from the inside using the red emergency release cord, then leave it in place and call. Do not try to reattach a cable or inspect a spring under tension yourself.
• Photograph what you see. A quick photo of the sensor lights, the track, or any visible damage gives your technician a head start and helps confirm the diagnosis when they arrive. It takes thirty seconds and it’s worth doing.

How We Fix It

When your local Brock Garage Door Repair technician arrives, the first thing they do is run the door through its full travel and watch it. Not guess at it – watch it. They check sensor alignment and clean the lenses, test the limit and force settings on the opener, inspect the springs and cables for wear or failure, and look at the track for bends or gaps. Most of the time the cause is clear within the first few minutes.

From there, you get a written price before anything is touched. That number doesn’t change once work starts. Depending on what’s found, the fix typically falls under Garage Door Repair for mechanical components like springs, cables, and tracks, or Garage Door Opener Repair for sensor and limit issues. Both services are covered by the 365-Day Done Right Promise: if the repair fails within a year, we come back and correct it at no charge. Most jobs are resolved in a single visit. The technician leaves the site clean when the work is done.
