Water works intermittently. Ice always works. Nothing I do seems to bring it back, it works when it wants to. Filter out, still no work. When the water is not working, the LED door lighting doesn't come on either....but comes on with the ice dispenser and when the water works. When the water is NOT working, I've tested the switch on the water lever, and it IS working. I DON'T think it's the water valve because the door light doesn't come on either.

Seems like whatever circuit board turns on the valve and the lighting and such....is intermittent....but I don't know which part to buy. help!
