My ice maker water supply was periodically freezing where it entered the freezer causing the line to pop off the back and shoot water on the wall.  This was due to the water valve not completely shutting off which allowed water to build up and freeze causing a blockage in the line.  Replacing with this unit has fixed the problem.  I have an FRS20ZRG fridge.
