Are you frustrated because your garage door opens slightly but then stops abruptly, leaving you stuck? This comprehensive troubleshooting guide explores the possible causes and solutions for this annoying issue, helping you get your garage door functioning smoothly again.

Garage Door Opens Slightly Then Stops

Understanding Why Your Garage Door Opens Slightly Then Stops

1. Misaligned Safety Sensors

One of the most common reasons for a garage door to stop abruptly after opening slightly is misaligned safety sensors. These sensors, typically located near the bottom of the garage door tracks, are designed to detect obstructions in the door’s path. If they are misaligned or blocked by debris, they may mistakenly signal the door to stop moving.

2. Broken Springs

Another possible cause of a garage door opening slightly then stopping is broken or damaged springs. Springs are responsible for counterbalancing the weight of the door and assisting in its smooth operation. When a spring breaks, the door may struggle to open fully, resulting in it stopping prematurely.

3. Obstruction in the Door’s Path

Obstructions in the garage door tracks can also cause the door to open slightly then stop. Common obstructions include debris, dirt, or even small objects that have become lodged in the tracks. Inspect the tracks carefully and remove any obstacles that may be impeding the door’s movement.

4. Issues with the Opener

Faulty garage door opener components can also contribute to the problem. Issues such as worn gears, damaged motor, or faulty circuitry can cause the opener to malfunction, resulting in the door stopping unexpectedly.

How to Fix a Garage Door That Opens Slightly Then Stops

1. Check and Align the Safety Sensors

Start by inspecting the alignment of the safety sensors. Ensure that they are facing each other directly and that there are no obstructions blocking their view. Use a level to verify their alignment and adjust them if necessary.

2. Replace Broken Springs

If you suspect that broken springs are causing the issue, it’s essential to replace them promptly. Garage door springs are under high tension and should only be replaced by experienced professionals to prevent injury or further damage.
