LED light indicators: Check the light blinks on your sensors when you try to close the overhead door. By checking it, you can tell if it’s out of alignment.
If you see green lights, the sensors are working. On the other hand, red light means your sensors are not aligned.
If you see red lights, check the bracket or try tightening a screw on the sensor.
