Our fridge started leaking water out into the floor, we removed the lower back cardboard like piece so we could see inside. There are 2 tubes near a plastic fan, one of them has been rubbing up against the metal around the fan, this has cut the tube. When we went to move the tube in came completely apart. One end of the tube seems to go up inside the refrigerator side (maybe, not sure) and the other end of the tube goes under the freezer and then up into the freezer door. Can we fix this and if so how, PLEASE help???
I have looked in the parts section of this website, but I can not seem to find which tube this is. 
If you have a parts supplier near you or a home depot, or a lowes, you can buy a pastic coupler to join the two lines together. It would make your life easy. Tom http://www.applianceeducator.com
