Why Does Garage Door Stop When Opening

Garage doors have become an essential part of our daily lives, providing convenience and security to our homes. We rely on them to open and close smoothly, allowing us to access our vehicles and storage spaces without much hassle. However, there are instances when garage doors don’t function as expected. One common issue that many homeowners face is a garage door stopping suddenly when opening. This article aims to explore the various reasons behind this problem and how to address it.

Why Does Garage Door Stop When Opening

Understanding the Mechanism

To comprehend why a garage door might stop when opening, it’s essential to understand its mechanism. Garage doors operate using a complex system of components, including springs, tracks, rollers, and an opener. The opener, controlled by a remote or wall-mounted switch, initiates the door’s movement. When you press the button to open the garage door, the opener’s motor engages, causing the door to move along its tracks.

Common Reasons for a Garage Door to Stop

Several factors can cause a garage door to stop abruptly during the opening process. Here are some of the most common ones:

  1. Obstructed Tracks: One of the primary reasons for a halted garage door is an obstruction in its tracks. Dirt, debris, or even small objects can get lodged in the tracks, preventing the door from moving smoothly.
  2. Broken Springs: Garage doors are equipped with springs that help in lifting the heavy door. If one of these springs breaks or malfunctions, it can disrupt the door’s movement and cause it to stop.
  3. Sensor Issues: Modern garage doors often come with safety sensors that detect obstacles in the door’s path. If these sensors are misaligned or malfunctioning, they can mistakenly signal the door to stop.
  4. Opener Problems: The garage door opener itself can be the culprit. Electrical issues, worn-out components, or a malfunctioning motor can lead to sudden stops.
  5. Lack of Maintenance: Regular maintenance is crucial for the smooth operation of a garage door. Neglecting maintenance can lead to various problems, including sudden stops during operation.

Troubleshooting the Issue

If your garage door stops when opening, you can perform some troubleshooting steps before calling a professional:

  1. Check for Obstructions: Inspect the tracks for any debris, objects, or obstructions. Remove them carefully to allow the door to move freely.
  2. Sensor Alignment: Ensure that the safety sensors on both sides of the door are aligned properly. Clean them from any dirt or spider webs.
  3. Test the Opener: Check the garage door opener for any visible issues. Listen for unusual sounds or vibrations when operating the door.
  4. Inspect Springs: If you suspect a broken spring, it’s best to leave this repair to professionals, as dealing with garage door springs can be dangerous.
  5. Regular Maintenance: Consider scheduling routine maintenance for your garage door. A professional inspection can catch potential problems before they cause interruptions.


A garage door that stops when opening can be frustrating, but understanding its possible causes and performing some basic troubleshooting can often resolve the issue. Remember that safety should always come first, and if you’re unsure about the problem or how to fix it, it’s best to seek assistance from a qualified garage door technician. Regular maintenance and care can also go a long way in ensuring your garage door operates smoothly and reliably.
