Jimmy F Roswell , GA May 27, 2016 Appliance: KitchenAid Ice Cube Maker KUIS15NRXB0 Kitchenaid Ice Maker Kuis15nrxb0: Intermittently not making ice and/or reduced production. How to replace Temperature Sensor. I searched the web and found tech articles on my KUIS15NRXB machine. A couple of them show a table of diagnostic LED steps as well as flow diagrams showing in detail the steps and concepts of this ice making machine. The 4th step in the diagnostic showed the sensor was not properly detecting water in the reservoir so the machine never went into freezing mode. The part can be replaced with a little patience, long arms and a 1/4 inch nut driver! I put down 3 for level of difficulty, not for the installation itself, but the diagnosis. works GREAT. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
