Need help programming craftsman 1/2 hp garage door opener (model number 139.53513) with new car remote visor.
There is no learn button. On one side are two knobs: up force and down force. On the other side are two recessed screws to increase travel up or down. On the side with the knobs, there is another sticker with a serial number of 41a3063.
