Sears Garage Door Opener

I have a Sears opener model 139.536151SR. The problem when I opened the door it kept going untill it hit a bolt,it did not stop. I thought it might be a limit switch problem I checked them they checked ok so I swapped the circuit board from my other opener. It did the same thing as before so then I thought I would just swap the limit switch assembly to see,that also didn't change anything either. I have an opener that works that I can use as test unit but I'm not sure what else to try. Any ideas would be appreciated. Thanks, Woody
