Question about KitchenAid KSM90 Ultra Power Series Stand Mixer
Hi, SUSAN ? Sorry to hear about your mixer?s problems. You have a couple of issues that need to b be addressed. Your KA mixer?s internal gears are factory packed with enough grease to last a lifetime (whatever that means?). Depending on the age of your mixer and how long it's been idle and/or how heavily it?s been used; these factors will eventually cause the grease?s base oil to separate from its additives, with the resultant oil seeping from openings beyond the gasket and generally following the path of least resistance to an exit point, e.g.; the brush covers or motor air vent, particularly since it was resting on its side during moving. Gravity can be very insidious. Depending on how much oil was lost, it is possible that friction between the gears may cause overheating, so you probably should look at replacing the grease in the mixer?s transmission box. However there is a larger concern and that?s if the oil, in its quest to seep out of the mixer, found its way into the electric motor compartment and the motor components. The only way to check if that occurred is to actually take your machine apart and look inside. The inspection and troubleshooting of the inside of your mixer is a DITY (or you spouses) capability, particularly if your mixer is out of warranty. Just be sure to have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website. Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case, try KSM90P, and select one of the files listed under Parts List (check to see it this matches your mixer model). Turn to pages 4 & 5, titled ?Case, Gearing and Planetary Unit?, which provides and exploded view for the disassembly and reassembly of your mixer, along with all the parts. The transmission case gasket is Illus. # 18, which you might want to reorder for starters. Once apart you can check for any other unseemly wear and tear on the gears, etc. It can be messy but gratifying to fix your own mixer. As far as parts go, here are four potential KA parts vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com. Prices can vary widely between vendors for the same part so do some comparison shopping. Finally, here's a link to an excellent site that details the disassembly and replacement of a mixer's grease, which might be helpful, too. http://www.foodonthefood.com/food_on_the_food/2009/04/how-to-repair-a-kitchenaid-mixer-yourself.html You?ll also need to inspect your electric motor components to see if any of them have been contaminated with oil. On page 6 of the Parts list manual, titled ?Motor And Control Parts?, you want to carefully inspect all the components, particularly Items # 8, 28, and assembly 32, and anywhere else in the motor compartment that may have been contaminated with oil. Grease is good for lubricating gears, but bad for electric motors. Any parts exposed to oil will need to be degreased and dried before reassembly. I use GUNK degreaser and blow-dry the parts with a hair dryer or toaster oven (N.B. Be exteremly careful when doing this). If you feel this is beyond your capabities and will be too difficult to do by yourself you can take your mixer to a local small appliance repair shop and have them troubleshoot and fix your mixer. KA Customer Care can provide you with the name and phone # of the closest authorized KA repair shop in your area or you can do a Online web search, but be sure to get at least three estimates before deciding to commit to one repair shop. Good luck. I hope this helps. Howard, Burke, VA If this solution has helped you, please rate it, thanks! - hslincoln
