Piero C Cle Elum , WA December 12, 2020 Appliance: Model KITCHENAID K4522WH KitchenAid stand mixer would not run on all speeds. No slow speeds at all medium speed ok but no top speed. I replaced the speed control plate. Part # WPW10119326. Replacing the plate was dead easy. Speed adjustment was a bit tricky. I referred to a YouTube video for guidance. https://www.youtube.com/watch?v=pUo_ZU5xh3o 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
