I have 2 Compool/Pentair CSA-24 valve actuators. One of them isn't working- doesn't respond either from the manual switch or from commands from the controller.
I removed the cover of both of the actuators. When I probe AC voltage coming into the unit, I get 29 VAC on both the good and bad units (I believe this was across the black and orange wires coming in from the controller). So the bad unit is still getting power. But when I manually toggle the switch:
- On the good unit, I now see 29 VAC on some of the output wires from the PCB that go to the motor while the motor is turning
- On the bad unit, I don't see any voltage on those same output wires
I do see a couple of places that sell replacement parts (including the switch set, gear set, etc), but given that I dont know exactly what is wrong it seems like it might just be time to replace the whole thing.
BTW- how easy is it to replace the valve actuator? Do I need to replace any of the PVC around the valve? I'd rather not start hacking up the pipes and have to buy a bunch of new fittings and have to get out the PVC cement
