Derek for Model Number ZISB480DMB 4 weeks ago the water and ice dispenser stopped working no touch controls or lights worked. Over the last 2 weeks the frig and freezer would not hold temperature freezer in the 20s and frig in the 50s but then it would bring the temperature down. Now the temperature is in the 30s and 60s.
