I’ve been using a KitchenAid Bottom-Mount Refrigerator for just over two years. Last week, I encountered a problem where the cold water dispenser located inside the refrigerator stopped dispensing cold water. I pulled out the refrigerator and took a look and nothing seemed out of order. I knew the dispenser itself was “working” because I could hear it attempt to pump water whenever I pressed the button.
So, after much searching around, I finally was able to locate the cold water tank behind the two crisper bins. Seriously, the owner’s manual should tell people to check the water tank within “The water dispenser will not operate properly” section of the troubleshooting guide. Even though the refrigerator says it is 38°, I know for a fact that certain parts of the refrigerator are colder than others. For example, leaving a gallon of milk on the top shelf by the blower will cause the milk to freeze. Anyways, a thin layer of ice had formed in the water dispenser tank. I didn’t even need to heat up the tank. Just tilting it back and forth caused the ice to break up. When I pressed the water dispenser button again, it started pumping out cold water (with a few ice crystals here and there.)
