I have a Craftsman .5HP GDO with the programmable DIP switches. My daughter just got a car and a friend of mine gave me a garage door handset for his old GDO. The handset does not have the programmable DIP switches so I am not sure how to program in the code into this handset. I looked at my GDO and it does have a program button and red LED that comes on when I push the program button. Does anyone have any suggestions?
