What's the LED supposed to do?
Sending sensor (usually one side only): solid green. Receiving sensor: solid red, amber, or green depending on brand, LiftMaster is green, Chamberlain varies, Genie is red. If either side blinks, flickers, or goes out, the beam is broken. Sun hitting the receiver lens at the wrong angle can also cause a blink that magically clears at sundown.
My sensor lens is dusty, do I just wipe it?
Yes, that's the first thing to try. A soft dry cloth on both lenses fixes about 15% of sensor issues. Next, eyeball the alignment, both sensors should point straight at each other with no tilt. If that doesn't do it, the wiring or the sensor itself is the issue.
