Compatible Garage Door Openers
I have two garage doors w/ different gdo units. One is a model # 139.53660SRT1 that is using a Sears Trinary Radio Control, and the other unit is model # 139.53992D which uses a 139.53753 remote. Both remotes are working fine with their respective gdo however I cannot program them to work with the other gdo. Is this possible? What do I need to do. I have the manuals for both and read them, and tried all of the "programming" suggestions but nothing seems to work.
