You should call Rainbird for technical support. Only they will be able to look at the controller with you and tell you if its fried. Either its fried or something is off in your programming. Also, with a power outage, Program B will be erased and A will revert back to a default.

If you are a do it your-selfer. Remove all the controller wires and clean out and anything inside that shouldn't be there. Of course do this after disconnecting power to the controller. Connect all the wire again and see what happens. If one station has a problem move the wire to another station and see if is okay then. Move a wire from a good station and move it to the bad one. You will determine what is bad, the station or the wire and solenoid valve. Let us know what you find. Or hire someone who will do this for you. aloha

^^^ what he said!

LABEL the wires and take a couple of pictures of the wiring, then disconnect it and clean out the case.

Thanks to lehua49. I switched the wiring from station one and two to stay 3 and 4 and it works perfectly. Looks like the contacts for one and two are shot. It never occurred to me to switch the wiring. Thanks again.

4 and 6 station controllers are not that expensive and many of the new ones are a lot easier to program than the old ones. If it were me I would just swap it out. You might be able to get a couple more years out of it by babying it but why bother... just replace it!
