As a homeowner, it's frustrating when your garage door won't close. There could be many problems, but here are the three most common:

Photo Eyes Misaligned or Blocked

The most common issue is misaligned or blocked photo eyes. You can tell if this is the problem if the garage door opener blinks its lights when you try to close the garage door. Most openers allow you to override this by holding down the wall button. This problem is usually fixed by adjusting the photo eyes or clearing the path under the garage door. Further related problems might involve wiring, photo eyes, or circuit board.

The Door is Obstructed

If there is an obstruction in the way of the door, it could be a dangerous situation. Garage doors weigh hundreds of pounds, so you don't want to be under it if it closes. Check to make sure that there is nothing in the path of the door. If the door still won't close, there could be a problem with the tracks.

The Cables Came Off and Are Tangled Up

This is the most dangerous situation. The door can't close because the cables are off and wrapped around the drum at the top of the door. It's important not to attempt to fix this problem yourself, as it can be very dangerous. Call a professional garage door repair technician to fix this issue.

Conclusion

Garage door problems are frustrating, but they don't have to be. By understanding the common issues that cause garage doors to not close, you can take steps to prevent them from happening. If you do experience a problem, don't hesitate to call a professional garage door repair technician for help.
