I ordered a new solenoid valve set and watched the online video of the replacement process. So after emptying my freezer and fridge, removing the doors and freezer drawer, so I could mover the fridge out of its cove, I discovered after taking the panels off the rear, that my fridge is different than that shown in the video. I went back online and discovered in one of the exploded views of the cabinet there is a panel inside the refrigerator which can be removed after taking the shelves out of the right side. Once I had the shelves out the panel easily snapped off when a screwdriver is used to release the retaining clips. With the cover off the valve was fully exposed and accessible. I snapped the valve out, released the Festo type water connectors, inserted the tubes back into the new valves, snapped the assembly back into the retainers, put the cover on, the shelves back in and reloaded the food. It took me about three hours to do this, but if I had only seen the drawing of the cabinet and not watched the video, it probably could have been done in about 20-30 minutes including unloading and loading all of the food.
Icemaker works great now.
