I have the same problem. To get your water flowing again use a hair dryer to heat the lower box area in the Ice/water dispenser nook. This will only get your water flowing again not completely solve the problem. I have same model same problem fridge is 3 yo and just started doing this. Use caution and aim heat down and away from plastic dispenser parts as too much heat will melt the plastic components QUICKLY. When box is warm it may take a few minutes for the water to flow again.
