Ronald A Carlisle , PA September 30, 2015 Kitchenaid stand mixer motor would run planetary (mixer head) would not turn Originally I thought the worm gear had gone bad - the most common problem when the mixer head won't turn. Got a new worm gear and took extraapart the mixer (followed the instructions in an online video tutorial). The worm gear was fine! The problem turned out to be that the small metal pin that secures the worm gear and drive shaft together was missing (?). Don't know where it went or if it was ever there in the first place, but without it the drive shaft and worm gear do not work together to turn the planetary. This is a 10 year old mixer and it has worked fine until just recently. Crazy. Installed the pin and put everything back together, and it's fine. Kept the extra worm gear for use in the future, if needed. Read More... 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes Tools: Pliers, Screwdrivers

Chris P Seattle , WA April 16, 2025 Appliance: Model K5SSWH Grinding noise in k5ss mixer The main culprit of the mixer not working was the worm gear (as usual). Girlfriend was unaware of limiting the mixer's speed to 2 for bread doughs, so she wore out the worm gear. It was a family item passed down to her with zero maintenance, so it needed new gaskets, grease, o-rings, etc. anyways, so between a full re-grease and a new worm gear it runs great now. The linked video tutorials for each part were super helpful and appreciated! Read More... Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes Tools: Screwdrivers
