    Garage Door Opens By Itself

    Your overhead garage door is your first line of defense in keeping your homes safe and protected all the time, and when it malfunctions on you, it can be a very big problem.

    This is because it leaves you and your home vulnerable to all kinds of unwanted factors and situations like theft, extreme temperatures, dust, and etc.

    But what should you do when your garage door opens by itself even when you have previously made sure to have it closed?

    Well, there is one thing you can be sure of is that if ever you do find yourself in a situation like this it surely is troublesome.

    When garage doors open by themselves, this can be triggered by a lot of different things like issues with your garage door remote, limit settings, sensor, programming, etc.

    The first thing you should do in a situation like this is to find what is causing the problem in order to address it accordingly.

    Depending on the complexity of the problem, you can attempt to solve it yourself or have a garage door repair technician help you out.

    No idea where to start with? Don’t worry, we got your back.

    Here is a list of things you can consider checking out whenever your overhead garage door opens by itself.

    1. Garage door remote and switch

    Your overhead can be lifted open and close using two things — your garage door remote and your wall-mounted switch.

    So if your garage door keeps opening for no reason, one of the main suspects for this is your remote and switch.

    It is entirely possible that the open button on both devices is lodged or stuck causing it to keep opening your garage doors even after you close it.

    To confirm this, check if your garage door remote and/or garage door switch’s open button is indeed stuck or stick briefly down before bouncing up again.

    Whatever the case may be, make sure to have it repaired right away before it gets worse, and do not leave it unattended without checking on it in order not to compromise the safety of your homes.

    2. Same frequency and/or code used by your neighbors

    Garage door remote functions in a way such that it communicates with your garage door opener through a certain frequency with a code only unique to your opener instructing it to lift open your garage doors.

    So, if ever anyone within your vicinity uses the same code and frequency as you do with your garage door openers, then they may end up accidentally opening your garage doors as well when they open their own overhead garage doors.

    This is a very uncommon case, however a very plausible one as well.

    When you find yourself in a situation like this, there is one way to confirm your suspicions – try opening your garage doors and when you do, see around if any of your neighbor’s garage doors open as well.

    If your neighbor’s garage door opens, then this is a clear indication that you indeed are using the same code and frequency as your neighbor.

    To correct this problem, you will need to reprogram your garage door remote.

    The method of reprogramming your garage door’s remote should be unique depending on the model of your garage door opener and its brand so if you have no idea how to do this, you may go ahead and check your opener’s user manual for further instructions.

    After reprogramming your garage door remote and opener, check and confirm if any of your neighbor’s doors still open at the same time that you open yours.

    If this is no longer the case, then you have successfully solved your problem at hand.

    3. Faulty and misaligned sensors

    Next on your list to check is your overhead garage door’s sensors.

    Garage doors have safety sensors that automatically reverse opens your overhead garage door whenever it senses something that may be obstructing your door’s pathway and the like.

    So when your garage doors are about to close and while in the midst of closing suddenly opens again, it could be because of your safety sensors.

    In order to fix a problem such as this, all you need to do is to make sure that nothing is obstructing the pathway underneath your overhead garage door sensors.

    Once you have done and made sure of this, try closing your garage doors again.

    If the same thing happens, then this could mean that your sensors are misaligned, or worst, damaged.

    Realigning and replacing your garage door’s safety sensors can be a bit challenging and difficult to do especially for a complete novice so it is best to ask and reach out to your local garage door repair technician for help.


    Aside from the above-mentioned points, there are a lot of other possible causes as to why your garage door opens by itself, however, let us stick with the most common ones.

    Knowing what could possibly be causing your garage door to behave this way contributes a lot to the way you need to handle the problem.
