Why does my garage door opener reverse on its own?
less than a minute readApr 19Lyle Weischwill
If the garage door reverses when closing after only traveling down an inch or so, something is probably blocking the beam between the two safety sensors at the bottom of the rails, or the sensors aren't aligned. Watch our safety sensor troubleshoot video to determine whether the sensors work; replace them if they're broken.
If your garage door reversing when closing after it's more than halfway down, you may need to adjust the downforce setting or adjust the door tracks so the door doesn't bind up on the way down.

The safety sensor has a pair photoelectric eyes at the base of the rails-one eye emits an infrared beam and the other receives it. If an object, person or animal blocks the beam, the closing door reverses direction. Test the sensor eyes by connecting them to short wires directly at the motor unit. While holding the sensors close together and facing each othe, click the remote. If the door doesn't close and the lights don't blink, replace the safety sensors.
