Icemaker just stopped making ice one night

I pulled the refrigerator out from the wali slowly so not to damage the water line to the ice maker. Then with a nut driver I removed all the screws holding the back plate on. Being careful not to kink the water line, I used the adjustable wrench to losen the water line feed nut and the nut that goes to the line to the icemaker. Then I removed the screws holding the valve in place finished unhooking the water lines with my fingers. I then got the new valve and finger tightend the main water supply nut to the inlet side, then I pushed the plastic supply tube going to the icemaker into the valve. The new valve does not use a nut to attach the tubing it is a presure fit very easy.
