A garage door that won’t close is almost always reacting to something: the safety sensors do not see each other, something is in the door’s path, or the opener thinks the door has hit an obstacle. In most cases the fix takes a few minutes and no tools. In others, the door is refusing to close because a spring, cable or track has failed, and forcing it will make the damage worse.
This guide covers the nine most common reasons a garage door will not close, in the order a technician would check them. Each one includes what you will see, what you can safely try and when to stop. If the door is stuck open and you need it secured today, our emergency garage door repair team serves Houston and the surrounding areas.
Quick Answer
The most common reason a garage door won’t close is a blocked, dirty or misaligned safety sensor. Check that both sensor lights near the floor are solid, wipe the lenses and clear anything in the doorway. If the door reverses after touching the floor, the travel limit needs adjusting. If the door looks crooked or you see a gap in the spring, stop and call a professional.
How to Tell What Is Stopping Your Garage Door From Closing
Watch what the door does when you press the button. The way it fails tells you where to look first.
| What the door does | Most likely cause | Who should fix it |
|---|---|---|
| Does not move; opener lights flash | Safety sensors blocked or misaligned | You |
| Starts down, then reverses | Obstruction, sensor issue or close force | You, then a technician |
| Touches the floor and goes back up | Close travel limit set too far | You or a technician |
| Closes with the wall button held, not the remote | Sensors or remote | You |
| Closes unevenly or hangs crooked | Broken cable or spring, door off track | A technician |
| Stops partway and makes grinding noise | Bent track or worn rollers | A technician |
9 Reasons Your Garage Door Won’t Close
1. Something is blocking the safety sensors
Every opener made since 1993 has two photo-eye sensors mounted a few inches off the floor on each side of the door. If the beam between them is broken, the door will not close. A trash can, a broom handle, a bike tire or even a spider web in front of the lens is enough. Clear the area and try again.
2. The sensors are out of alignment
Sensors get bumped by cars, bins and kids. When they no longer point at each other, one of the indicator lights will blink or go out. Loosen the wing nut on the bracket, aim the sensor until its light turns solid, then tighten it. Our step-by-step guide to fixing garage door sensors covers blinking light patterns in more detail.
3. Dirty lenses or direct sunlight
Dust, mud splatter and condensation scatter the infrared beam. Wipe both lenses with a soft, dry cloth. If the door only refuses to close at certain times of day, low sun is probably hitting the receiving sensor. A small shade over that sensor, or swapping the two sensors to opposite sides, usually fixes it.
4. Damaged or loose sensor wiring
The thin wires that run from each sensor to the opener can be chewed by rodents, pinched by a staple or corroded at the terminals, which is common in humid Houston garages. If both sensor lights are off, or one flickers when you wiggle the wire, the wiring needs repair. This is low-voltage work, but tracing a break along the wall and ceiling is often easier for a technician with a meter.
5. The close limit is set wrong
The travel limit tells the opener how far to move before it stops. If it is set too far, the door reaches the floor, the opener keeps pushing, reads the floor as an obstruction and sends the door back up. Most openers have a limit adjustment screw or a set of programming buttons on the motor unit. Adjust in small steps and test after each one. Owners of that brand can also see our guide to a Chamberlain garage door that won’t close.
6. The close force is too low
Openers also measure how hard they are pushing. As a door ages, rollers and hinges add friction, and the opener may decide it has hit something. Raising the close force slightly can help, but it is not a cure. If the door needs noticeably more force than it used to, something is binding and should be found.
7. The track is blocked or bent
Look along both vertical tracks for dents, gaps at the joints, loose brackets or debris. A small stone or a hardened lump of grease can stop a roller. A bent track will make the door slow down, shudder and reverse at the same spot every time. Loose bracket bolts can be tightened, but a bent track should be straightened or replaced by a professional so the door does not come off its rollers.
8. A broken spring or cable
If one side of the door sits lower than the other, a cable is slack or hanging loose, or you see a gap in the spring above the door, stop using the opener. The door is no longer balanced, and it can drop or twist in the tracks. This is a job for a trained technician with the right bars and clamps. Our broken cable repair service handles frayed and snapped cables the same day in most cases.
9. A remote, wall control or opener fault
If the door closes from the wall button but not the remote, replace the remote battery first. Then check the wall control: many have a lock or vacation button that disables remotes. If nothing works and the motor unit shows no lights, check the outlet and the breaker. An opener that clicks or hums without moving the door may have a failed capacitor or logic board.
How Do You Close a Garage Door That Won’t Close?
When you need the garage secured right away, there are two safe ways to get the door down, as long as the springs and cables are intact.
- Hold the wall button. On most openers, pressing and holding the wall button until the door is fully closed overrides the safety sensors. Keep the doorway in sight the whole time.
- Close it by hand. With the door as low as it will go, pull the red emergency release cord to disconnect the opener, then lower the door slowly using the handle. Lock it with the slide lock if it has one.
Do not use either method if the door is crooked, a cable is loose or a spring is broken. A door without spring support can weigh 150 pounds or more, and it will come down fast.
What Should You Not Do When the Door Won’t Close?
- Do not tape, bypass or remove the safety sensors. They are required by federal safety rules and they protect children and pets.
- Do not keep pressing the button over and over. Repeated attempts overheat the motor and can strip the drive gear.
- Do not turn the force setting all the way up to push through a problem.
- Do not loosen spring hardware, cable drums or bottom brackets. They are under high tension.
When Should You Call a Garage Door Technician?
Call a professional when the sensors are aligned and clean but the door still reverses, when the door is uneven or noisy, when you can see damaged springs, cables or tracks, or when the opener has no power or makes a humming sound. A door that suddenly gets loud is often warning you first; our guide to a noisy garage door explains what each sound means.
Most of these repairs are finished in one visit. If you are searching for garage door repair near me in Houston, Pearland, Missouri City or Stafford, ask for a company that tests the safety reversal and door balance after the fix, not just the part that failed.
Frequently Asked Questions
Why does my garage door start to close and then go back up?
The opener is detecting a problem and reversing for safety. The usual causes are blocked or misaligned safety sensors, an object in the door’s path, or a close-force or travel-limit setting that needs adjustment.
How do I force my garage door to close?
On most openers you can press and hold the wall button until the door is fully closed, which overrides the safety sensors. You can also pull the red emergency release cord and lower the door by hand. Use both only as a temporary measure, and never if a spring or cable is broken.
Why won’t my garage door close when it is sunny?
Direct sunlight can hit the receiving sensor and drown out the infrared beam. Shading the sensor with a small cover, swapping the two sensors to opposite sides or moving them slightly farther back in the frame usually solves it.
Why does my garage door close with the wall button but not the remote?
If the wall button works, the door and opener are fine. Replace the remote battery, check that the wall control’s lock or vacation mode is off, and reprogram the remote if needed.
How much does it cost to fix a garage door that won’t close?
Sensor realignment or replacement typically costs $85 to $250. Track, roller, spring or cable repairs cost more, generally $125 to $350 depending on the part.
