Valve Actuator not working properly

[markphin]

thanks for the reply. If the problem was at the actuator it self, would it still not work even by flipping the switch on the actuator. When I flip the switch on the actuator, the valve turns. It's when I push the button on the unit in the house or at the spa or at the main board, that it does not work, which would lead me to believe it is somewhere on the board or within the "brain" it self.
I will try switching the wire harness at the board. Are these easy to replace?

Well switched the harnesses as suggested and the valve worked, which indicates a problem on the circuit board right. I played around a bit, making sure things were tight. Still not working. Any body have suggestions. I made an appointment for service on the 5/23. But would love to be able to figure it out and cancel the appointment. Any help would be appreciated.
