Skip to content If your garage door starts to close but stops before reaching the ground, there are several possible causes. The problem could be something simple, such as an obstruction or dirty sensors, or it could indicate an issue with the springs, cables, tracks, or garage door opener. Here are some of the most common reasons your garage door may not be closing completely.
1. Something Is Blocking the Door
Check the area underneath and around your garage door for objects, debris, or anything that could be preventing the door from closing completely. Even a small obstruction can cause the door to stop or reverse.
2. The Safety Sensors Are Misaligned
Garage door safety sensors help prevent the door from closing when something is in its path. Dirt, debris, or misaligned sensors can cause the opener to stop the door before it reaches the ground.
3. The Garage Door Tracks Are Bent or Damaged
Your garage door needs properly aligned tracks to move smoothly. Bent, damaged, or obstructed tracks can cause the door to bind, stop, or close unevenly.
4. The Garage Door Springs Are Worn or Broken
Garage door springs help support the weight of the door as it opens and closes. Worn or broken springs can make the door difficult to operate and may prevent it from closing properly.

5. The Garage Door Opener May Need Adjustment or Repair
If the door consistently stops before reaching the floor, the opener’s travel limits or other components may need adjustment or repair. An opener that is struggling to operate the door can also indicate a larger mechanical problem.
What Should I Do If My Garage Door Still Won’t Close?
Start by checking for obvious obstructions and making sure the safety sensors are clean and properly aligned. If the door still won’t close completely, it’s best to have the system inspected rather than repeatedly forcing the opener to operate.
