Craftsman Garage Opener
I just moved into a house with a single garage door opener, Craftsman, 1/2 HP, Model 139.539.60SRT. In the past month the garage door has opened "on it's own" 3 or 4 times. I attempted to reprogram the remote and followed the instructions on the opener. All lights "appear" to be functioning as stated, however, now the remote will not operate the opener. The door will open and close properly with the button on the wall, but nothing with the remote. When the remote is pushed the green light on the opener itself is flashing so the signal is there which tells me it's not the battery. Please HELP!
