Why my garage door won’t close?


If you’re experiencing difficulties with your garage door not closing, it can be frustrating and inconvenient. Understanding the potential reasons behind this issue can help you troubleshoot and resolve the problem efficiently. In this article, we will explore some common causes for a garage door not closing and provide possible solutions to get it working again.

1. Sensor Misalignment

One of the most common reasons for a garage door not closing is sensor misalignment. Garage doors are equipped with safety sensors that detect obstructions in the door’s path. If these sensors are not aligned properly, they may prevent the door from closing. Check if the sensors are clean and aligned correctly. If not, adjust them until the indicator lights are solid and not blinking.

2. Obstruction in the Door’s Path

Another possible reason for a garage door not closing is an obstruction in its path. Check for any objects, debris, or even small animals that may be blocking the door’s movement. Remove any obstructions and try closing the door again. It’s essential to keep the garage area clear to avoid such issues in the future.

3. Issues with the Garage Door Opener

The garage door opener itself can also be the culprit behind a door that won’t close. Check if the opener is receiving power and functioning correctly. Inspect the opener’s motor, gears, and drive system for any signs of damage or wear. If necessary, consult the manufacturer’s manual or contact a professional for repairs or replacement parts.

4. Broken Springs or Cables

Broken springs or cables can prevent a garage door from closing properly. These components are responsible for counterbalancing the weight of the door, allowing it to open and close smoothly. If you suspect a broken spring or cable, it is crucial to seek professional assistance as these repairs can be dangerous and require specialized knowledge and tools.

5. Track Misalignment or Damage

The tracks on which the garage door rollers move can become misaligned or damaged over time. Inspect the tracks for any bends, dents, or obstructions. Use a level to ensure they are properly aligned. If you notice any significant damage, it is advisable to contact a professional for repairs or replacement.

6. Malfunctioning Remote Control

Sometimes, the issue may not lie with the garage door itself but rather with the remote control. Check if the batteries in the remote control are functional and properly inserted. If the batteries are fine, try reprogramming the remote control to the opener. Consult the manufacturer’s manual for specific instructions on how to do this.


A garage door that won’t close can be caused by various factors, including sensor misalignment, obstructions, issues with the opener, broken springs or cables, track misalignment or damage, and malfunctioning remote control. By identifying the specific cause and following the appropriate troubleshooting steps, you can resolve the issue and restore your garage door’s functionality.
