There could be a few reasons why the garage door opens by itself. One possibility is that the wind is blowing it open. Another possibility is that there’s something caught in the door that’s pulling it open. A third possibility is that there’s a problem with the door opener, and it’s opening the door automatically. Whatever the reason, it’s important to find out why the door is opening and fix the problem.
