Today the gray tank to the shower won't open. The cable is connected, the handle still works, but the gate doesn't.
It worked just a couple days ago..

So the rod has either unscrewed from the valve blade or stripped the treads out. Disconnect the cable and see if you can screw the rod into the blade. Our 4 year old Bighorns black tank valve was getting hard to open. I poured about 4 ounces of marine head lube in the tank the last cycle on use and the valve now operates easier than it did when new.
 
Mine is doing the same thing. Worked after I first got it, but now it won't dump. The only thing I can think of is its leaking because it's not closing all the way. I'll keep messing with it.
