Pulled out the fridge from the wall, unplugged it, and turned off the water supply. Took off the cardboard backing at the bottom of the fridge. Cleaned the dust and gunk. Unscrewed the old valve. Unplugged the 3 electrical connections. Since the new fittings for the water lines were different, we unscrewed the old ones, lopped off the nipples, and inserted the ends of the water lines into the new connections (they were super easy - just push the line in until it clicks). Reattached the valve. Reattached the cardboard. Turned water back on, and plugged in the fridge. Our ice maker still didn't make cubes, though. So I took out the fill valve from the top rear of the fridge. It had a tiny piece of ice lodged in the bend of the back, right above where it connected to the water line. I rinsed it out, reinstalled, and now we have a full bucket of ice!!
