Craftsman garage door opener questions

Posted by fairlaniac (My Page) on

I have a Craftsman opener installed model 139.53975SRT and the sprocket shaft busted. I have an older unit I want to put in place of the broken unit, it's model number is 139.53615SR. Since the wiring terminals are labelled differently cand someone direct me on how to wire the older unit with the wiring that is installed? I have the three button wall unit and the sensor wires to hook up. Is this possible? See pics here (you may need to cut/paste)

The older opener is wired correctly except the red wire and the white wire connected to terminal 1 should be reversed. Check the wall control. It is printed on the small circuit board where the red and white wires go.
