craftsman garage door opener
I have a two-door garage with an opener on each. In the past month, one of them started opening by itself periodically. Also, the remote for the other door has started to control the one that's opening by itself. (The indicator LED light is blinking constantly on the one that's opening by itself.) I've tried erasing the codes, but I can't seem to get the remotes straight again. No matter what I do, both remotes only work for the door that opens by itself. The other door cannot seem to "learn" a new code.
I thought, perhaps, lightning has shorted out the one and it is in constant learn mode, therefore, the other remote defaults to it each time.
