Why Does My Garage Door Keep Opening? (11 Reasons Why)

Garage doors are automatic and should be systematically programmed to open when they detect the presence of a car in front of them.

But sometimes, the door will not fully close or close at all. Here’s what I will reveal about why your garage door is opening itself!

Why Does My Garage Door Keep Opening?

1. Never Fully Closed

Being partially closed is the most frequent cause of a garage door that keeps opening.

Unfortunately, you can’t be sure your door is locked unless you watch it go down and close.

Along with this, the spring on your garage door opener is intended to prevent the door from opening accidentally, but if the spring is damaged or frayed, it won’t function as intended.

Therefore, if it isn’t fully closed and you still see the light at the top of your garage door, then there’s a good chance that your garage door is never fully closed to start with!

2. Programmed Remotes To Several Buildings

When you want to open the garage door, you must use a remote control or key. For this reason, you must ensure that the remote control or key is working correctly.

Moreover, once your remote control is programmed to open several buildings, it may just be trying to open the garage door, not just the one you want it to go to.

If this is the case, ensure you only have one remote control centralized with all of your buildings’ codes.

Overall, if you program too many garage doors, they will all open when someone tries to use one of them!

3. Extreme Weather Conditions

In extreme weather conditions, such as snowfall or high winds, a garage door can become stuck on its tracks and will not open properly.

Apart from this, high humidity levels in your area can cause your garage door to stick or even lift off the track due to friction between its metal pieces and the frame underneath them (metal-to-metal contact).

In addition, if you have a sagging door, it could start opening when there is a strong gust of tornado.

Which is why many homeowners notice that their garage doors keep opening after a storm or windy day!

4. Reversed Limit Switch

A garage door limit switch is an electric device that detects when the door is being opened and closes the circuit.

Meanwhile, it will keep the door’s bottom or top section from opening. So when you hear the sound of your garage door opening, there are two things at work.

First, out of a reversed limit switch, the second is by a torsion spring.

On that account, the door may refuse to fully close or reverse itself as the homeowner tries to close it if the limit switch is reversed!

5. Blocked Electronic Photo Sensor

Garage doors have an electric photo sensor that detects when a person or a vehicle is on the property. The sensor uses infrared light, invisible to humans but can be seen by the sensor.

As such, this type of sensor is used for safety purposes so that someone opens your garage door without using the remote control and closes it again before leaving.

Above all, if there is any obstruction in front of the sensor, it will not detect them until after they’ve passed through the obstacle and opened up again!

6. Accidentally Pressed Or Stuck Remote Buttons

Accidentally Pressed Or Stuck Remote Buttons

You can operate your garage door opener with a push of a button.

However, if you have kids in your house, you will find that they are likely to press the wrong button when they are playing around and accidentally open the door.

By that very fact, if you see them pressing any buttons on their toy remote control, immediately stop them and ensure they do not press any remote keypad again!

7. Frosted Door With Ice And Snow Deposition

Frosting is a common problem for garage doors. Over time, the bottom of your door can become coated with frost.

Although this doesn’t mean that your door will eventually stop working, it will take longer for the frost to melt.

Consequently, formed frost crystals on garage doors would typically remain suspended until heated again by warm air, causing your gateway to stay open!

8. Faulty Circuit Board

A circuit board that regulates your door’s opening and shutting is what malfunctions in garage doors most frequently.

That being so, when there is an electrical problem on this part, it will result in problems with other electrical appliances.

As a consequence, if the circuit board is worn out, it could cause the door to open unexpectedly!

9. Smoke Damage To Sensors And Cables

When your garage door opens, it’s not just an inconvenience. When it keeps on opening, it can also be a safety hazard.

That being the case, when smoke is present, the sensor will detect it. In order to avoid this happening, make sure that there is no smoke or fire around your garage door opener.

After all, once they’re damaged by smoke, they can get stuck in their “open” position and stay there indefinitely!

10. Defective Control Wirings

Some faulty wiring symptoms indicate dimming or flickering lights.

If your garage door is acting up, there’s a good chance it’s because the control wirings don’t work correctly.

Because of that, you should also check for loose wiring that can cause problems with the door’s operation!

11. Same Frequency To Other Garage Door

Your garage door opener’s radio frequency might be compatible with your neighbor’s new door.

In that case, someone else may be able to open your door with their remote if two nearby openers are set to the same channel.

For that reason, their remote control might be able to open the garage door that happens to be set to the same frequency as yours!

Any property would benefit significantly from having an automatic garage door. However, if your garage door keeps opening, the issue may be something you aren’t doing.

Extreme weather conditions, never fully closed, programmed remotes to many buildings, and other factors may also impact.

Because of this, it’s critical to take preventative measures to maintain your garage door operating correctly!
