Why Does Your Garage Door Randomly Open By Itself

Your garage door serves a vital part in keeping your residential homes safe and protected all the time.

Without them, you will make yourself and the people around your vulnerable to a lot of risks and danger among all other things.

But what happens if your garage doors suddenly open by themselves?

Imagine yourself in a situation like this; wouldn’t it be quite unsettling and troublesome?

One of the most troubling problems that can happen to your overhead garage doors is phantom opening or the act of your door opening by itself.

When this happens, it puts your safety at risk and even leaves you vulnerable to a lot of unwanted factors and situations.

But exactly why does your garage door randomly open by itself?

Well here are three possible reasons as to why such a thing is happening and the appropriate response you should do if ever you find yourself in a situation like this.

1. Signal Interference

Garage doors use frequency in order to access its basic functions, opening and closing the doors.

Whatever method you use to open your overhead garage doors remotely, the frequency must be the same for both the opener and your remote.

The problem with this is, a lot of other things use frequency for their basic functions as well which could result in it interrupting your garage door’s functions such as walkie-talkies, radios, and others.

This being said, it also implies that other garage door openers function the same way as yours does, like your neighbors.

In some instances, although extremely rare, two different garage door openers can be programmed unintentionally to use the same frequency and code for their basic functions.

Because of this, when your neighbors open their overhead garage doors, they also end up opening yours as well.

Fortunately, remedying this can be really easy.

All you need to do is reprogram your garage door openers in order to change the code and frequency that it is using and it should no longer respond to your neighbor’s garage door remote.

2. Obstruction on your garage door’s path

Garage doors have a safety feature where they reverse open whenever they hit something or if they detect something on the door’s pathway.

And sometimes, dust and debris hide and accumulate on your garage door’s floor surface.

So when your garage door’s sensor detects this debris or if your garage doors hit these, they are wired to reverse open automatically and this could be one of the reasons as to why your garage door opens by itself.

To solve this problem, you just have to make sure that nothing is obstructing your overhead garage door’s path or that there is nothing that your sensor can detect down there.

Doing this will make sure that your garage doors are closed properly and will not open themselves again.

3. Check your garage door’s remote

Lastly, when your garage doors open themselves suddenly, this could be due to your garage door’s remote.

When we say garage door remote, there are two things that could possibly be causing this, either your ‘open’ buttons are stuck in place and continuously fighting open signals to your garage door opener, or your garage door remote’s batteries are running out of juice.

If it has been a while since you last replaced your garage door’s batteries, then it should be time to do so now.

If it is your open button that is stuck on to the remote’s housing for some reason, try and see what is causing it to stick to your remote.

If you can fix the problem yourself, then that would be good but if you are having a hard time doing so, make sure to call the nearest garage door repair company to help you out.
