There is nothing you can tweek on the inside. There is no phasing either... It's all pretty simple stuff really. Often I see a lot of corrosion that builds up around the black shaft in the back. What gets me is that it worked well up to this point (?) and now it quit.
Disconnect the cable from the unit. You can manually run the unit (by rotating the large spur gear) and check that each lobe of the small cam actuates the counting switch by listening to the click. Also you can check that the homing switch mounted on the casting actuates when the cam pushes back on it. You should also feel more resistance to turning of the large spur gear when the switch engages. If you have both switches working, chances are good that it's not the pcool. Again, make sure that the black shaft rotates freely. You said that the motor moves the nozzle, so the motor is okay.
We have had I/O board issues with regards to the PCOOL circuit. This would require you to have a HFO tech out there... IF and when the tech comes out, have him demonstrate to you that the new board will work.
Let me know if this helped.
