A garage door that refuses to close is more than just an inconvenience. It can create safety concerns, leave your home exposed to weather or intruders, and cause daily frustration. If you’ve ever pressed the button and watched your door start to close, only for it to stop halfway or reverse back open, you’re not alone.
This is one of the most common calls we get at Precision Garage Door. Homeowners often ask, “Why won’t my garage door close?” The good news is that many of the causes are simple, while others signal it’s time for professional garage door repair.
In this guide, we’ll cover:
- The most common reasons a garage door won’t close properly
- Quick troubleshooting steps you can try
- When it’s time to schedule a repair with a professional
- Tips to prevent the problem from happening again
Common Reasons a Garage Door Won’t Close
Misaligned or Dirty Safety Sensors
Modern garage doors are equipped with safety sensors, also called photo eyes. They sit at the bottom of the door, near the floor, and send an invisible beam across the opening. If anything breaks that beam, the garage door won’t close.
Dust, dirt, or even spider webs can interfere with the sensors. A small bump from a car, a lawn mower, or even kids playing in the garage can knock them out of alignment.
What to do:
- Wipe the sensor lenses with a soft cloth.
- Check that both sensors are pointing directly at each other and are level.
- Look for blinking lights, which usually indicate a misalignment.
If the door still won’t close after cleaning and realigning the sensors, the wiring or sensor itself may be damaged and need professional replacement.
Obstructions in the Track
Another simple but common reason for a door refusing to close is something in the track. Even a small rock, toy, or buildup of dirt can block the rollers and stop the door’s movement.
What to do:
- Inspect both sides of the track for debris.
- Make sure the rollers are clean and able to move smoothly.
- If you see dents or bends in the track, don’t try to force the door—this can make the problem worse.
A badly bent or misaligned track is a repair for a trained technician. Precision Garage Door offers same-day garage door service to safely realign or replace damaged tracks.
Broken or Worn Garage Door Springs
Your garage door springs do the heavy lifting every time you open or close the door. If one of these springs breaks, the door may close unevenly, slam shut, or refuse to move at all. A door with a broken spring may feel extremely heavy if you try to move it manually.
This is one of the most dangerous repairs to attempt on your own. Garage door spring replacement requires specialized tools and training. Attempting to DIY this repair can result in serious injury.
Signs of a broken spring:
- A loud snapping or popping noise before the door stopped working.
- Gaps in the spring coil.
- The door looks crooked when closing.
If you suspect a broken spring, call a professional garage door repair company immediately. Precision Garage Door offers emergency garage door repair for spring issues because we know how urgent this situation can be.
Garage Door Opener Issues
Sometimes the problem isn’t with the door itself but with the opener. Each opener has settings for travel limits and force. If these settings are off, the opener may think the door has already hit the floor and reverse before it should.
Other opener-related issues include worn-out gears, electrical problems, or a failing motor.
What to do:
- Check your opener’s limit settings (usually found on the side of the unit).
- Try replacing the remote batteries.
- If the opener is older, consider upgrading to a new smart garage door opener for reliability and convenience.
If adjustments don’t solve the problem, call for a professional inspection. Our technicians at Precision Garage Door are trained to repair and install all major opener brands, including LiftMaster, Chamberlain, and Genie.
Track Misalignment or Damage
Your garage door runs on a set of tracks that guide it smoothly up and down. If those tracks become bent, misaligned, or loose, the door may jam or refuse to close completely.
Signs of misaligned tracks include:
- The door looks uneven when closing.
- You hear grinding or scraping noises.
- Visible gaps between the rollers and track.
Attempting to force a door down when the track is damaged can lead to more expensive repairs. Professional garage door technicians have the tools to safely realign or replace tracks to restore proper operation.
When to Call for Professional Garage Door Repair
Some issues are safe for homeowners to troubleshoot, like cleaning sensors or removing debris. But other problems, like broken springs, damaged tracks, or opener failures, require professional garage door service.
Here’s when to pick up the phone:
- Your garage door feels unusually heavy when trying to open manually.
- You notice broken or dangling garage door springs.
- The door closes unevenly or slams shut.
- The opener makes grinding noises but doesn’t move the door.
- You’ve tried basic troubleshooting but the problem persists.

How to Prevent Garage Door Closing Problems
Like most mechanical systems, your garage door performs better with regular maintenance. Scheduling a tune-up once or twice a year can prevent many common issues.
Tips for garage door maintenance:
- Keep safety sensors clean and free of obstructions.
- Lubricate rollers, hinges, and tracks with a silicone-based spray.
- Watch and listen when your door operates—unusual sounds often mean something is wearing out.
- Test the door balance by disconnecting the opener and manually lifting the door. It should move smoothly and stay halfway open.
- Have a professional inspect your springs and opener at least once a year.
Regular maintenance not only keeps your door running smoothly but also extends its lifespan and helps you avoid costly emergency repairs.
