I had one at a customers doing the same thing - nothing. Went through checking all of the wires it told to do on the tech sheet. Bottom line, the actuator was bad. It takes 3 minutes to install a new one. What I figured out was that if actuator motor goes bad and is out of position, it will do nothing.
I now carry 2 actuators on my truck. If I encounter same problem, its easier to just change actuator then to be checking all of those wires from control to motor and actuator. I also carry a lid lock, strike, control (there are a couple different ones for these machines), and several of the electronic pressure / temp switches. With lid lock and strike, you can just plug new one into control to see if that is the problem. Not carrying a motor yet, haven't had one go bad.
