    Why Is Your Garage Door Mysteriously Opening

    Your garage door is a key entry point to your home. When it doesnt work correctly, you may not feel safeor secure. If your door opens on its own, take a look at the top possible causes.

    Sensor Malfunction

    Garage doors made after 1993 have safety sensors that detect objects in the way of a clean close. These sensors stop the door from closing on a person, pet, or car that gets in its way. Without properly functioning sensors, its possible for someone or something to get stuck or injured by a closing door.

    Older doors may have a physical sensor. When the door touches an object it reverses automatically. Most newer doors have photo eye sensors. When an object passes through the sensors line of sight it trips the sensor, causing the reversal mechanism to kick in.

    Dirty, misaligned, worn, or incorrectly wired sensors can malfunction, causing the door to open when nothing obvious is blocking the way. If you store household, garden, or other items in your garage, make sure to keep them away from the sensors. A rake, sled, or other object can set off the sensor or stop it from working properly.

    If youve cleared everything from the area, dusted the photo eyes, and made sure theyre aligned but your door still opens unexpectedly, contact a garage door professional to evaluate and repair the problem.

    Opener Malfunction

    Most garage doors have openers on the exterior , on the interior, and as a remote. A malfunction of any type of opener can cause your door to behave strangely.

    You Need To Adjust The Travel Down Setting

    How To Fix A Garage Door Opening By Itself | Clear Garage Door Codes

    The travel down setting of your garage door opener controls the distance the garage door has to travel before it completely closes. If it closes before the set distance is met, it may have detected something, so it goes back up to prevent damage or safety threat. However, your garage door components may sometimes contract and change due to weather changes. In this case, the distance may change. So adjusting the travel down setting to a new distance can fix the issue.

And this is another reason you need to hire a professional garage door repair company to inspect your garage door regularly.

    The Remote Control Is Defective

    The issue may be down to the remote control to your garage door. If the remote is defective, or the batteries are wearing down, then it may start sending out random signals, including the one to open and close the door. Change out the batteries to see if that resolves the issue. If it doesnt, you can buy a new remote to see if that will help. Its a fairly inexpensive fix, so its worth trying out if youre not sure whats causing this problem for you.

    You Have A Bad Wall Button

    Because most wall buttons have integrated circuit boards, they can intermittently trigger your garage door to activate. Even your basic doorbell style buttons include small circuit boards behind the plastic housing. Even though a wall button circuit board could be intermittent, its not the most common issue we encounter.

    As a wall button is used over time, the button will start to wear down. As you press this button, you will notice it jiggles or has a lot more play than it did when it was new. The worn out button can accidentally activate your automatic opener when someone closes the walk through door going from the garage into the home.

    I know this may be hard to believe, but we have seen occasionally where the deep soul rattling bass from a large V-8 motor or Harley-Davidson motorcycle was powerful enough to cause a worn wall button to activate. I didnt believe it at first either, but after witnessing it at a customers home, it was true. You learn something new every day.

    The Openers Limit Settings

    When you try to close your garage door, does it come back up partway after reaching the ground? Or, perhaps when you open it, the door comes back down partway? If this is happening, then your limit settings probably need to be adjusted.

    The limit settings tell your garage door how far up it needs to go to open and how far down it needs to go to close. If these limits are set incorrectly, once the door makes contact with the ground, or reaches the top, it can continue moving in the the other direction. If you think your limit settings are off the mark,
