Garage Door Opener
Have old 1/3HP Sears Craftsman garage door opener Model#139.663801. Bought new remote from Liftmaster remote #63LM. I thought I was programming it exactly like the old remote. Well, it doesnt work so maybe I accidently changed some of the numbers on the old one.ha There is no "learn"
button nor is there code switches on the back of the motor unit. There are no buttons...only a red light on the plug- in unit beside the garage door. Where do I find the codes? so I can set my remote correctly. Thank heavens my car remote works to open it. HELP!!!!!
