A garage door that mysteriously opens on its own can be unsettling. Not only does it pose a security risk, but it also leaves homeowners puzzled and concerned. If your garage door keeps opening on its own, take a look at the top possible causes and their solutions.
Sensor Issues
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. They are typically located near the bottom of the garage door tracks and work by sending an infrared beam across the doorway. Without properly operating sensors, it’s possible for someone or something to get stuck or injured by a closing door.
Older garage doors may have a physical sensor that reverses the doors direction when it touches an object. Most newer doors have photo eye sensors. When an object passes through the sensor’s 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 supplies, garden tools, or other items in your garage, make sure to keep them away from the sensors. A shovel, bike, or other belongings can set off the sensor or stop it from working properly. Even dust, cobwebs, or even direct sunlight can interfere with the sensors’ operation, leading to false signals that trigger the door to open unexpectedly. Be sure to clean the sensors with a soft cloth and ensuring they are properly aligned.
If you’ve cleared everything from the area, dusted the photo eyes, and made sure they’re aligned but your garage door keeps opening randomly, it may be time to contact a garage door professional to evaluate and repair the problem.
Opener Malfunctions
Most garages have an exterior garage door opener keypad, an interior opener, and a remote. A malfunction of any type of opener can cause your door to behave strangely or open unexpectedly.
For instance, if a wall garage door opener button gets dirty the buttons can stick, forcing it to stay in the on position. This results in a continuous open-close cycle of the door. Ensure the button is not pressed down, and clean it if necessary. Gently wiping the opener may clean loose debris way. If the door continues to malfunction after cleaning the opener and its buttons, the garage door may requires professional help.
If the interior garage door opener keypad isn’t at fault, check your remote control. Low batteries, sticky buttons, or improperly stored remotes can cause the door to keep opening. Never store your remote under other items. An accidental bump to one of the remote keys could open the door when you don’t want to.
It is also possible the wiring from the opener to the door is worn or faulty. Like with a faulty sensor eye, this is another issue best left to a qualified garage door technician.
Radio Wave Interference
Beyond mechanical issues, radio frequency interference can also cause your garage door to open randomly. Both keypads and remote openers rely on radio frequencies to communicate with automatic garage door openers. But these aren’t the only nearby devices that could be using radio waves. A nearby radio, wireless network, or appliance may accidentally interfere with your garage door’s operation if they’re both tuned to the same frequency. Often, simply moving or turning off the other device can resolve the issue.
Neighbor’s Garage Doors
The radio frequency your garage door opener uses may match your neighbor’s garage door, especially if they recently installed a new system. If two nearby openers are programmed to the same channel, it’s possible for someone else to operate your door with their remote. Talk to your neighbors or have them test their opener on your door. If their remote interfering with your door, reprogram your unit to correct the problem.
Conclusion
A garage door that opens on its own can be both inconvenient and alarming. Whether the issue stems from an opener malfunction or radio wave interference, understanding the root cause is the first step to resolving it.
