Louis L Westborough , MA April 10, 2015 Kitchenaid mixer did not work I received a free defective mixer that did not spin. I replaced a worm gear, gasket, and speed knob. Gave it a wipe down and it's as good as new. Very easy fix. Cheap too. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
