Never could use those other DIP switch transmitters. It was done another way. We had to find the matching receiver for the dip switch transmitter and then wire that up. Remember that I'm not privy to any other detail than what's in your post.
Have a Sears GDO with a learn button and red LED. How do you program it to DIP switch transmitters.
Have pressed and held learn button on opener and red LED next to it lights. Pressed button again and pressed transmitter. LED goes out as it recognizes transmitter.
Pressing transmitter button again does nothing.
Also tried pressing learn button and transmitter button simultaneously but still won't activate opener. One time the GDO ran when I repeated above steps but just for about one second. What is the method to learn a transmitter?
