The garage is one of the houses' biggest entry points, so when the door seems to open on its own, the problem creates a serious safety concern. If the door is opening on its own, understand that what is happening is not some random act; there is a reason behind this problem. To protect your home and family, its best to get to the bottom of it as soon as possible.
Battery or Remote Wear
If your garage door seems to open on its own, the first place you want to look is at the opener remote. If the batteries are weak, they might not respond immediately. In this instance, it might take a couple of moments for the remote to respond and open the door.
If the period is long enough, you could be in the house already, and unaware that the door is open. This problem is also common with older remotes, as over time, the buttons can start to shift and stick. Once this happens, the button could be locked, causing the door to open as soon as the remote is in range.
A common problem in populated areas is code scrambling. Each garage door system uses a different code or frequency to function. As a result, your opener doesn't respond to your neighbor's garage door and vice versa. However, there are only so many codes.
As the neighborhood becomes more populated, there is a possibility that someone else's system will use the same code as yours, which would cause your door to respond whenever they use their remote. The next time your door opens on its own, see if any of your neighbors are nearby opening their garage. Having the code adjusted on your opener will resolve the problem.
An issue with the wiring could also be to blame for any issues you experience with your garage door opening on its own. Particularly in the case of a power surge, the bolt of power can damage the wiring that supports the control board of the opener.
While the door might function, because the control board is faulty, it will respond and operate intermittently, which means the door could open and close seemingly on its own. In this type of scenario, the control board should be replaced, and a surge protector installed to prevent a future issue.
If the issue with your garage door doesn't resolve itself with a quick battery or remote replacement, it's time to contact a repair professional from a company like Edgemont Garage Door Service to ensure your safety and prevent damage to the door and opener system.
