Craftsman Garage Door Opener Remotes
I have a Craftsman garage door opener 1/2 HP model 139.19470D. Remotes are 139.18791B and they do not work. Tried new batteries, reprogramming remotes, clearing the memory and reprogramming remotes again. Opener works fine from the wall mounted switch. The light is 'not' flashing on the wall mount switch. When programming the remotes everything appears normal. The lights blink indicating that the code has been accepted. We've had the opener for about 3 years but just recently installed it. Any ideas?
