Refrigerator water valve from wall is not dispensing water
The valve at the wall may not be the problem at all even though it was stiff. I have on quite a few occasions found water supply lines for refrigerators and ice machines connected using a saddle valve the type that you strap around a pipe and it punches a hole in the pipe, this is where I find the problem much of the time the tiny opening gets blocked or corroded and the water stops flowing, I usually turn off the water cut the pipe and install a T with a 1/4” fitting and valve reconnect the waterline and things work again. Copper and pvc/cpvc are easy with galvanized shark bite fittings do the job , I don’t use the saddle valves because they always fail in time and it is usually a leak, only sometimes no water.
