Why won’t my garage door stay down?


If you’re experiencing issues with your garage door not staying down, it can be frustrating and inconvenient. A garage door that won’t stay down can compromise the security of your home and may indicate an underlying problem. In this article, we will explore some common reasons why garage doors fail to stay down and provide possible solutions to help you troubleshoot the issue.

Potential Causes and Solutions

1. Misaligned Safety Sensors: One common reason why a garage door won’t stay down is due to misaligned safety sensors. These sensors are designed to detect obstructions and prevent the door from closing if something is in the way. If the sensors are misaligned, they may falsely detect an obstruction and cause the door to reverse. To fix this issue, check if the sensors are properly aligned and clean any dirt or debris that may be obstructing them.

2. Broken Springs: Garage doors are equipped with springs that help balance the weight of the door and assist in its operation. If the springs are broken or damaged, the door may not stay down properly. Broken springs can be dangerous to handle, so it’s recommended to seek professional assistance to replace them.

3. Malfunctioning Garage Door Opener: A malfunctioning garage door opener can also be a reason why the door won’t stay down. The opener may have a faulty sensor or other internal issues that prevent it from properly closing the door. In this case, you may need to troubleshoot the opener or consider replacing it if necessary.

4. Limit Switch Problems: The limit switch is responsible for controlling the travel distance of the garage door. If the limit switch is not set correctly or is malfunctioning, it can cause the door to stop before reaching the fully closed position. Adjusting or replacing the limit switch can help resolve this issue.

5. Damaged or Worn Rollers and Tracks: Over time, the rollers and tracks that guide the garage door can become damaged or worn out. This can cause the door to become misaligned and prevent it from staying down properly. Inspect the rollers and tracks for any signs of damage or wear, and replace them if necessary.

6. Obstructions or Debris: Sometimes, an obstruction or debris on the garage floor can prevent the door from closing completely. Check the area around the door for any objects that may be blocking its path. Additionally, ensure that the tracks are clear of any debris that could interfere with the door’s movement.


A garage door that won’t stay down can be caused by various factors, including misaligned safety sensors, broken springs, malfunctioning openers, limit switch problems, damaged rollers and tracks, or obstructions. By identifying the specific issue and implementing the appropriate solution, you can restore the proper functionality of your garage door. If you’re unsure about any aspect of the troubleshooting process, it’s always best to consult a professional garage door technician to ensure safety and effective repairs.
