More Craftsman Garage Door Opener Problems?
Modell 139.53636SRT Been having range problems. Then the it opens for a foot, returns, etc etc,to the point I can't even use it. Continually. I have disconnected all the opener units including the sensors. I can still plug the opener in to electric and still the opener does the same. Even Disconnected the trolley from the door to see if it stopped. Still stop and go, stop and go. Also the little green lED that you press to configure the codes continues to FLICKER. I thought this only comes on when you press it. I have had this since Oct 1994. Now I'm wondering since I have 4 remote units at $39 a piece, can I use them on a new one I purchase? I'd hate to get a new unit and then have to toss the old remotes, and then buy new ones for the new unit. Any advice would help.
