Garage Door Won't Close? 7 Common Causes & How to Fix It

Garage Door Won't Close? 7 Common Reasons & How to Fix It

A garage door that won’t close is more than just an inconvenience — it can quickly become a security risk. An open garage door can leave your home, vehicles, tools, and personal belongings exposed to theft, weather damage, and unwanted access.

At GTA Garage Door, we help homeowners throughout Toronto and the Greater Toronto Area with fast, reliable garage door repairs. Our technicians handle these issues every day, from simple sensor adjustments to major repairs involving springs, cables, tracks, and garage door openers.

In this guide, we’ll explain the 7 most common reasons your garage door won’t close and what you should do next.

1. Blocked or Misaligned Safety Sensors

One of the most common reasons a garage door won’t close is an issue with the photoelectric safety sensors located near the bottom of the garage door tracks.

These sensors are designed to detect objects, children, pets, or anything blocking the door’s path. If they are dirty, blocked, or misaligned, your opener may prevent the door from closing.

Check the following:

• Make sure there are no objects blocking the sensors
• Remove dust, dirt, or spider webs from the sensor lenses
• Confirm both sensor lights are on and steady
• Make sure the sensors are facing directly toward each other
• Gently clean the lenses with a soft cloth

If the sensors are clean and properly aligned but the door still will not close, they may need adjustment or replacement. Our technicians regularly repair and replace faulty garage door safety sensors.

2. Broken or Worn Garage Door Springs

Garage door springs do the heavy lifting by supporting the weight of your door. When a spring breaks, the opener may not have enough power to move the door safely.

Common signs of a broken spring include:

• A loud popping or banging sound from the garage
• A visible gap in the torsion spring
• The door opens only a few inches and stops
• The opener runs but the door does not move
• The garage door feels unusually heavy when lifted manually

Important: Garage door springs are under extreme tension and can be dangerous to replace without proper tools and training. Never attempt a spring replacement yourself. Professional garage door spring repair is the safest solution.

3. Damaged or Broken Garage Door Cables

Garage door cables work together with the springs to safely lift and lower the door. When cables become frayed, snap, or come off the cable drum, the door may become stuck, crooked, or unable to close properly.

A damaged cable is also a safety concern because it can cause the door to become unstable.

Signs you may have a cable problem:

• One side of the door is lower than the other
• The door looks crooked or uneven
• The cable is hanging loose
• The door gets stuck halfway

If you notice damaged cables, avoid using the door until it has been inspected by a professional.

4. Bent, Misaligned, or Blocked Garage Door Tracks

Your garage door tracks guide the rollers as the door moves up and down. If the tracks become bent, loose, or blocked, the door may stop closing properly.

Check for:

• Bent or damaged tracks
• Loose brackets or hardware
• Dirt, debris, or objects blocking the track
• The door closing unevenly or getting stuck

Never force a garage door that is off track. Doing so can damage the panels, rollers, opener, or other hardware.

5. Garage Door Opener Limit Settings Need Adjustment

Your garage door opener uses limit settings to know how far the door should travel when opening and closing.

If the closing limit is incorrectly adjusted, the opener may think the door has reached the floor too early and automatically reverse back open.

This issue can often be fixed by adjusting the opener settings. If you are unsure how to adjust it safely, our garage door opener repair technicians can diagnose and recalibrate the system.

6. Worn Rollers, Hinges, or Other Hardware

Over time, garage door rollers, hinges, and moving components wear down. Excessive friction can prevent your door from closing smoothly.

Signs of worn hardware include:

• Loud squeaking noises
• Jerking or shaking while closing
• Slow or uneven movement
• The door getting stuck during operation

Replacing worn rollers and maintaining your garage door regularly can improve performance, reduce noise, and help prevent unexpected breakdowns.

7. Remote Control, Keypad, or Opener Problems

Sometimes the garage door itself is working properly — the issue is with the device sending the signal.

Possible causes include:

• Dead remote battery
• Remote losing programming
• Signal interference
• Faulty keypad
• Opener receiver or logic board problems

Try these quick checks:

• Replace the remote battery
• Use the wall-mounted garage door button
• Reprogram the remote
• Check if other remotes work

If the opener still does not respond, the problem may require professional opener repair.

When Should You Call a Garage Door Professional?

Some problems, such as dirty sensors or dead remote batteries, are simple fixes homeowners can safely handle.

However, if the issue involves:

• Broken springs
• Damaged cables
• Bent tracks
• Door coming off track
• Opener failure

…it is best to call a trained garage door technician.

Garage doors are heavy systems with high-tension components. Attempting repairs without the proper experience can lead to serious injuries or additional damage.
