Opener.also had a Light switch type switch located in Garage for operating opener. Unable to find any information in Manual. Any Clues? Bob
The old eye beams and controller may or may not work. The remotes definitely will not. If they do, they will probably cause problems over the long run. Best thing to do is to go ahead and replace them. But if you like the old button, give it a try. Some more basic older ones will work, you just may lose some of the features like door lock or light control.
