Sears Craftsman Garage Door Opener HELP!
I have a Sears Craftsman 1/2 hp garage door opener that only works from the wall unit. I bought a new remote and programmed it but it does not help. I changed the light bulb. It does not help.
The learn indicator light blinks in a series of 4 blinks. What does this mean? I don't have a manual. HELP!
