Do your garage door opener lights flash and the door won’t close?
Your safety reversing sensor must be connected and aligned correctly before the garage door opener will close. An obstruction in the path of the sensor will also cause your door to not close.
This sensor is an electronic beam, which is sent between two sending and receiving “eyes”. These eyes face each other and are located just inside your garage door. They may need to be adjusted so the beam from the sending eye is properly detected by the receiving eye. Once the receiving eye “sees” the beam from the sending eye, a green indicator light will glow on the top of the eye.
