it seems that the valve is in need of replacement which I am going to do, but the question I have is that because of the valve problem, water froze in the feed line as it goes into the ice machine and split... Can you tell me two things. what is the part number for that line that runs from the ice machine back to the valve and also how difficult is it to change it. It simply sticks out out of the top of the freezer and there does not seem to be any access panels to get to it... On the back of the freezer the line just goes through a metal panel but that does not seem to be removable.. Help!! thanks
