Common Reasons Why Garage Door Opens by Itself

The automatic garage doors stay on the brighter side by allowing the owner to access the door with a single click on the remote control. It is super convenient to use, and you don't have to put in any manual effort. However, since it's an automatic device and does not have a particular life, it can stop or malfunction anytime.

Although automatic garage doors are super easy to use, they become tough to tackle once they malfunction.

Have you been facing the problem of the garage door opening back by itself lately?

Do not worry; we'll observe some common issues and help you fix them up.

Jammed control panel

The newer garage doors come with a fitted, mounted button to open and close the garage door other than the remote control. The garage door operator can easily spot this button, usually mounted inwardly.

If the garage door is opening and closing constantly, there must be a problem with the inside fitted button. The problem might be continually depositing dirt, dust, and grit. Poor maintenance might have pushed the garage door inside and stuck, making it unable to retract. Also, loosening up wires can cause the same problem.


First, you need to make sure that the button is in an off position and isn't stuck anywhere. Secondly, have a mope in hand and gently start cleaning the entire button and make sure to do not apply extreme force. Clean it thoroughly, and if it still does not work, open it up using appropriate tools. Cross-check the wirings and tighten them up if possible. If the I wires are broken, consider replacing the entire button system.

Faulty limit settings of Garage door opener

Garage door openers come with a garage door setting system which enables it to sense the path where it has to stop. The faulty setting can cause the problem, which leads to its constant opening and closing. The significant advantage of limit settings is that they can be manually fixed.

Limit settings are essential for your garage door since they stop when they sense the floor. If the limit setting is sifted too high, they constantly stop in between as they sense the pressure and confuse it with the floor. Therefore you need to fix it by adjusting it.

How do you fix it?

If you do it manually, search for limit switch adjustment screws. However, most garage door openers can be fixed by simply making the changes through the remote control of the garage door. Use an appropriate screwdriver to set the limit screw as per the intensity of the glitch. Turn it three times in the clockwise direction.

If you find the manual process difficult, then rather than doing it forcefully, call a garage door technician to fix it for you. Since garage doors are sensitive and if you accidentally turn the settings to the lowest, the garage door can collapse down.
