Purchased replacement device from Appliance Parts Pros. Only difficulty with the whole process was getting the last bit of the hoses through the hole in the back of the refrigerator. The insulation that was attached to the hose with a trap was very difficult to get through the hole because of interference between the hose insulation and insulation in the wall of the refrigerator. Just took a bit of careful coaxing to get it through. Otherwise - it went as planned.
