Your garage door plays a significant role in home security and convenience, so it can be frustrating when it stops working properly. A garage door that won’t close is a common issue that homeowners face, and it can arise from various problems. Let’s look at some of the reasons behind this issue and how you might be able to address it.

1. Obstruction in the Garage Door’s Path

One of the simplest reasons why your garage door won’t close could be an obstruction blocking its path. Garage doors are designed with safety sensors near the base that detect objects in their way. These sensors prevent the door from closing when something is detected, ensuring no damage or injury occurs.

According to Abe’s Door Service Ltd., garage door materials include steel, wood, aluminum, or composite. If obstructed, each can experience different types of movement issues. To resolve this, inspect the area for items like toys, tools, or debris. Even something as small as a twig can trigger the sensors.

2. Misaligned or Dirty Safety Sensors

Garage door sensors are located near the ground on both sides of the door. Their job is to prevent the door from closing when something is in the way, but these sensors can sometimes become dirty or misaligned. Dust or dirt buildup can interfere with the signal between the sensors, leading to malfunction.

Similarly, if they’ve been bumped or moved out of alignment, they won’t work correctly. Cleaning the lenses with a soft cloth and ensuring they are properly aligned may solve the problem. A quick way to check for alignment issues is to observe the sensor lights. If they are blinking or not lit, that indicates a problem with alignment.

3. Issues with the Garage Door Remote or Wall Switch

Sometimes, the issue isn’t with the door itself but with the device you use to operate it. A remote control with dying batteries or a malfunctioning wall switch can prevent the door from closing. Try using the wall switch to close the door if your remote isn’t working.

If that works, the remote likely needs new batteries or needs to be reprogrammed. On the other hand, if both the wall switch and remote fail to work, the problem could be electrical, such as a blown fuse or an issue with the garage door opener’s motor. In that case, you may need to consult a technician for repairs.

4. The Garage Door Track is Bent or Damaged

Garage doors rely on smooth, well-aligned tracks to move up and down. Over time, these tracks can become bent, warped, or damaged due to regular wear and tear or accidental impacts. When the tracks are misaligned, the door might get stuck or struggle to close.

Check for visible signs of damage along the tracks, and if you notice any bends or warping, this could be the culprit. A professional may need to realign or replace the tracks if the damage is significant. Keeping the tracks clean and lubricated can also help prevent this issue.

5. Broken Garage Door Springs

The springs on your garage door are responsible for counterbalancing the door’s weight, making it easier to open and close. When one or both springs break, the garage door may stop functioning altogether, or it may close unevenly or not at all. Springs have a limited lifespan and will eventually wear out. If you suspect a broken spring, it’s important not to attempt to fix it yourself, as springs are under a lot of tension and can cause injury if mishandled. This type of repair should always be left to a professional technician who can safely replace the springs.

6. The Garage Door Limit Settings Need Adjustment

Garage door openers have limit settings that control how far the door moves when opening or closing. If these settings are not properly calibrated, the door might close too much or not enough. This can cause the door to stop prematurely, or in some cases, start reversing back up before it reaches the ground.

You can adjust the limit settings on your garage door opener to ensure the door closes completely. This can usually be done by consulting your opener’s manual for instructions on how to adjust the settings. If this doesn’t solve the issue, the opener itself might need to be repaired or replaced.


A garage door that won’t close can be the result of various problems, ranging from simple obstructions to more complex mechanical failures. Regular maintenance and cleaning of sensors, tracks, and other components can help prevent many of these issues. When in doubt, or when dealing with more complicated repairs like broken springs, it’s always best to call a professional to ensure the job is done safely and effectively. By addressing these common issues, you can keep your garage door functioning properly and avoid inconvenience.
