Why is My Garage Door Not Closing: Common Causes and Solutions

A garage door that won’t close can be a frustrating experience for homeowners, especially if the problem is recurring. There are several reasons why your garage door might not be closing, and it’s important to identify the root cause to fix the issue effectively. In this article, we’ll explore some common reasons garage doors don’t close and what you can do to solve the problem.

Fixing Garage Door Closure Issues: Common Solutions

Garage doors not closing can be a frustrating issue for homeowners. It can cause inconvenience and security concerns. Several reasons lead to this problem, including misaligned sensors, dirty tracks, worn-out rollers, damaged weatherstripping, and a malfunctioning garage door opener. This article will explore common solutions to fix the issue effectively.

  • The sensors are misaligned

Modern garage doors have sensors that detect objects in the door’s path. These sensors are designed to prevent the door from closing on people, pets, or objects. If the sensors become misaligned, the door won’t close. You can tell if the sensors are misaligned if the lights on the sensors are blinking. To fix this issue, you need to realign the sensors so they face each other directly. Check the manufacturer’s instructions for your specific garage door opener. In most cases, you’ll need to adjust the sensors manually until the lights stop blinking.

  • The tracks are dirty or damaged

Another reason why your garage door might not be closing is that the tracks are dirty or damaged. Over time, dust and debris can build up in the tracks, causing them to become clogged. This can prevent the door from closing properly. Additionally, if the tracks are bent or damaged, the door won’t be able to move smoothly along them. Clean the tracks thoroughly using a soft cloth and a mild cleaning solution to fix this issue. If the tracks are damaged, you may need to call a professional to repair or replace them.

  • The rollers are worn out

The rollers on your garage door are responsible for helping the door move up and down along the tracks. Over time, these rollers can become worn out, causing the door to get stuck or not close properly. If you hear strange noises when operating your garage door, this could be a sign that the rollers are worn out and need to be replaced. You can do this yourself if you’re handy or call a professional to do the job.

  • The weatherstripping is damaged

The weatherstripping on your garage door helps prevent drafts and moisture from entering your garage. Over time, this weatherstripping can become damaged or worn out, causing it to lose effectiveness. If the weatherstripping is damaged, it can prevent the door from closing properly. Inspect the weatherstripping on your garage door and replace it if necessary.

  • The opener is malfunctioning

Sometimes, the reason why your garage door won’t close is that the opener is malfunctioning. This could be due to a variety of reasons, such as a problem with the wiring or a faulty circuit board. If you suspect the opener is malfunctioning, you’ll need to call a professional to diagnose and fix the problem.


A garage door that won’t close can be a frustrating experience for homeowners. However, by identifying the root cause of the problem, you can take steps to fix the issue effectively. Whether it’s realigning the sensors, cleaning the tracks, replacing the rollers, or repairing the opener, several solutions exist. If you need help with garage door repair or are uncomfortable with DIY repairs, it’s always best to call a professional for help.
