make sure both ports in the solenoid chamber are clear of debris, strip the paper off of a twist tie and slide it through both the holes to make sure they are clear.

That can be a toughie.... first start by checking continuity to the valves and see what the resistance is... at both the clock AND at the solenoids. If there's more than a couple of Ohms difference, I'd start looking at the wire connections. Did you splice the wires between the clock and valves?
Next is the solenoid port. Some valves inherently have critical flow problems in the solenoid chamber (be sure it's clear) and need a "boost" (opening the bleeder or solenoid) when the diaphragm gets stiff when sitting unused. Fr'instance, like when you leave the system off for any extended period of time. Sprinkler systems are like cars... ya can't park 'em and come back weeks or months later and expect them to work perfectly.... every time. Unless you blow your system down for winter, run the valves a minute or two once or twice a week to keep it "lubricated".

Trouble shooting Hunter valves?

I installed a sysem on my own last season that has a rainbird controller wired to 2 hunter PGV-100GS valves. The system worked great for about 1 month. Then one of the valves would not open when programmed. If I went out to the box and hand turned the solenoid top, then the valve opens and it would close after programmed amount of time. the second valve worked as programmed. Now, it's time to using the system again, and neither valve will work when I have the controller activate them. What do you think the problem is?? I bought Hunter valves thinking they would work well. Are both solenoids bad? Is there something wrong with my wiring? I followed instructions to a T and used the waterproof grease fittings. Is something wrong with my controller? Any ideas on how to trouble shoot?

Thanks in advance,
