Understanding Sources of Garage Ghost Openings

In the garage door industry, when a garage door opens on its own for one of a variety of reasons, this is called “ghost opening.” Garages contain several mechanisms, and the failure of even one can lead to this kind of ghost opening, which can not only pose safety hazards to those nearby but can risk the security of your house when you aren’t home.

At Overhead Door Company, our garage door repair services include helping you identify the source of ghost openings and assisting you with correcting them. Let’s take a quick look at three of the most common reasons for this happening, plus what you can do about each of them to prevent these issues in the future.

In today’s day and age, the majority of garage doors are electrically powered, using a remote opener and sensors that help detect when there’s a blockage of some kind that should prevent the door from closing for safety reasons. These sensors are near the ground, and are generally very sensitive.

One of the single most common sources of ghost openings, then, is sensors that are tricked by various forms of debris. Perhaps this is a tool that wasn’t quite put away properly, or maybe it’s something that fell from the ceiling. If it is interfering with the sensors in your door, though, it may cause the door to rise on its own or fail to close. This should be the first area you check if your door continues to ghost open.

Radio Interference

In addition, modern garage doors utilize radio waves for their basic operation. When you type in a passcode entry, radio frequencies communicate this to the opener. The same is true when you press the buttons inside the garage or the buttons on your remote opener, which will be on the same frequency as the garage door and can cause it to open and close.

Garage doors, however, are not the only items out there that utilize radio waves. Police radios, CB radios and even other nearby garages might also be operating on the same frequencies, leading to interference issues. If this is the case, your fix is easy: Just reprogram the openers using a different frequency.

Opener Problems

Down similar but perhaps even simpler lines, you may be having issues with your garage’s remote opener itself. If this item is dirty, submerged in water or short on batteries, it may either simply not work or work in a faulty manner. Many garage opening and closing issues, including ghost openings, can be traced back to openers that were not in proper operating condition.
