Garage Door Opener: Why does my garage door opener open and close by itself?
When your garage door opens or closes when you haven't triggered the remote, one possible cause is that a neighbor's remote was programmed at the same time as yours. Erase all codes in your remote and then reprogram it. If that doesn't fix the problem, check the wiring between the motor unit and the wall control. Faulty wires can short together and trigger the motor unit to open or close the door. A defective wall control can cause the same problem. Our garage door opener wall control troubleshooting video will help you figure out the problem. Replace the wall unit if you find it has failed.
