Craftman Garage opener...bad antenna?
I have two craftsman garage openers. I finally got one to work with the remote...but the other opener is giving me lots of trouble. The remote will only work if I am holding the remote right next to the opener unit. The outside keyless opener also stopped working. It flashes a lot. Is it possible that I have a bad antenna? Does the outside keyless, battery operated pad also communicate via antenna? The remote, literally has to be right next to the unit. Standing under it doesn't work.
