Hi everyone I'm new here so I hope I am posting this in the right place. I'm having trouble with my Wayne Ralston garage door closing. I know it has to do with the sensors but I'm not sure what is wrong with them. I realign them (which is really hard since it seems they are really touchy) and I can close the door once. Next time they are out of alignment again and I have to do it all over again. It seems like maybe the infrared beam is really weak or something? I've tried cleaning the lenses but that hasn't helped. I'm not sure what to do next? Do I need to replace the sensors? Any advice would be appreciated.
