We all depend on our refrigerators, and most of us use our refrigerators frequently to dispense ice. So if you have a Whirlpool side by side refrigerator not making ice, we understand the frustration. There may be a couple of reasons you could discover your Whirlpool refrigerator not making ice but water works fine. The water system may be connected, but the ice maker has separate components that allow it to run independently. The best thing to do is troubleshoot a few items to determine the cause of the ice maker failure including water supply issues, problems with incoming power, temperature issues, and more.
