I am not to sure if this will work for your model, but if you look in the back of the freezer near the ice dispenser there should be a switch. The location may vary depending on the appliances brand. It might even be a button, but it should have a light beside it. My ice dispenser tends to short out so I flip the reset switch and it will turn back on again. Have you checked to see if anything is frozen up from dripping water in the back?
