Hi, like the subject says, the water line that comes out of the top of the freezer and dispenses water into the ice tray seems to keep freezing. I noticed the ice maker was not making any ice since we got home from vacation. Today I realized that the opening of the water line inside the freezer was frozen. Using a hair dryer, I melted the frozen water jamming the opening and it made some ice. However, I noticed that there is already some ice forming in the opening of the water line. What could be causing this? I should add that since we were away from the house for a few days, I turned off the water to the whole house. I started doing this after a friend came home to a flooded house from a break in a sink water line. Would this have caused any problems?
