If the cams are turning it's probably a frozen piston that has snapped the little chromed connector
that sits on top of the piston rod between the cams. Look for the halves laying in the plastic tray below.

If the cams do not turn, chances are good that you have a sheared pin.

Both issues can be fixed by me.

I checked the cams and the piston and both are moving like they should, the motor just keeps running unless I unplug it, do you know were home position is on the cams? I marked them so I would get them lined up when I changed the motor

@MMueller,
The rear cam switch should turn off the drive motor when it hits the notch in the rear cam. this would be the "home position " . The actuaton on the switch should pop out into the slot and shut it off. The cams are actually keyed so that they slide onto the hex shaft in the proper position.

@Joethewaterguy,
Thanks for the replys H20 man and Joethewaterguy, checked the micro switches with a meter and they are making and breaking, when the rear one pops out the whole operation starts over, also they are set for normally open, do you guys think I should change them anyway?

@MMueller,
one time I had this happen ,with all the connections in the correct position ,is when I replaced the orings and got some water splashed on the boards. I used a blow dryer on the circiut boards to dry out all the parts and connections. A little drop of water was sitting under one of the chips.

@MMueller,
They are rare.

I have a few in my shop, but I don't sell them separately.

@MMueller,
For me it's case by case. I refurbish and bench test the entire
control valve by replacing what's worn out and/or broken.

In your case I would need to know what generation board your Q has.
If I don't have a suitable replacement on hand there is no reason to move forward.

Price: It's not cheap, but it's less than buying a new replacement control valve.
