2 Possible Reasons Why Your Home's Garage Door Keeps Opening On Its Own
Posted on: 6 February 2023
While either in your garage or sitting in your house, you may have noticed that your garage door has started to open on its own. After replacing the batteries in the remote, the issue may still be occurring, leading you to wonder what is making the door open. If so, below are a couple of possible reasons why your garage door keeps opening even if you are not sitting in the driveway in your car.
1. One or Both of the Safety Sensors on the Sides of the Garage Door Are No Longer Aligned
One possible reason why your garage door keeps opening on its own is that one or both of the safety sensors are knocked out of alignment. These sensors send invisible lasers across to one another, and when the stream is broken, the door will open thinking it is you in your car approaching the door.
However, when they are no longer aligned, they will pick up other objects and movements that are not in the doorway of the garage which creates false signals to the opener to raise the door. To bring the sensors back into proper alignment, you will need to have a professional repair technician perform the work.
2. Lift Settings on the Garage Door's Opener Are No Longer Allowing the Door to Close Completely
Another possible problem that may be making your garage door open on its own is if the lift settings are no longer set correctly. Normally, the lift settings bring the door down to a specific level while it is closing.
However, if the settings are no longer correct, the door may not be closing completely, which sends a false indicator that there is an object under the door and engages the reverse mechanism to open it. A repair technician will be needed to reset the lift settings to get the garage door opener working properly again.
If your home's garage door keeps opening on its own, the safety sensors may no longer be aligned correctly and are picking up other objects or movements that send a signal to open the door. Or, the lift settings may not be set correctly and are no longer allowing the door to close completely, causing the reverse mechanism in the opener to reopen the door. Since either of these issues needs to be dealt with by a professional, contact a garage door repair service in your area to schedule a time for someone to come to your home to determine the cause of the problem and take steps to fix it.
