The speed on my K5SS mixer stays on the high speed. Moving the lever has no effect on the speed.
SOURCE: Mixer turns on revs to a high speed and then quits
I replaced the control board on mine, and that seemed to resolve the issue
I had a similar problem where the mixer would also go to fast speed right away. On the back at the top was a screw that was loose. After tightening this screw I had 4 speeds but no stir speed. I unscrewed that screw and a bolt fell out. This bolt went to threads on the inside of the area covered by that back plate. I put that bolt back on and tightened it and the corresponding one on the other side and wala the mixer works perfectly at all speeds. Hope it helps. Make sure mixer is unplugged before attempting anything like this (wires are exposed when the back plate is removed - some kind of flexible circuit board).

Hi DELUNAY. The only way to tell if your speed control assembly is bad it to remove it and test it a local repair shop, but I think from the symptoms you describe, you’ve already answered your own question and your speed control assembly is shot. The fact that your motor is not making any noise indicates to me that it’s not getting power. That can only be caused by two things; a bad speed control board or a burned out electric motor. When you shredded your nylon worm gear, did the motor exude a ‘bad/burnt’ smell (other than possibly ozone)? If not, then I would look at replacing your speed control board/assembly.
Since you know you’ve got to replace the worm gear, you might as well replace the speed control assembly. The inspection and troubleshooting of the mixer transmission is a DITY capability, particularly if your mixer is out of warranty. Just be sure to have the correct Part List manual around when you start to disassemble your mixer. If you're lacking one, you can download it from the KA website (http://www.kitchenaid.com/flash.cmd?/#/page/home).
Click on Customer Care>Locate Manuals& Guides> and enter the 6 character model number, in your case use KSM50P and then select the first files under Parts List (definitely check to see if it matches your mixer. If it doesn’t, continue to look at other manuals until you find the correct manual that does match.)
Turn to pages titled ‘Case, Gearing & Planetary Unit, for the disassembly, troubleshooting, and reassembly of your mixer, along with all the parts. This is where you’ll find your
Besides your shredded worm gear, you can check for any other unseemly wear and tear on the other gears, etc. You may find more parts that need replacement than just a bad gear. You should also consider replacing the grease, particularly if there are gear particles suspended in it.
Besides needing a replacement gear and grease, you might consider replacing the gasket, too. I recommend using a food-grade grease that you can order online (although I’ve seen automotive bearing grease used too – your call).
As far as parts go, here are five potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com; and Grainger.com. You should search for ‘food grade grease’. Prices can vary widely between vendors, so do your comparison shopping.
It can be messy but quite gratifying to diagnose and repair your mixer yourself. Oh and don’t forget to replace the speed control board and associated components, tool
Here are some links to several excellent websites that detail the disassembling/greasing and reassembly of a KA Mixer.
Between these three websites and their excellent pictures and descriptions and your Parts List manual, you should now be able to completely disassemble and reassemble your mixer.
Good luck and have fun. I hope this helps. Howard, Burke, VA

Testimonial: "Thanks for the advice and sources. Much more helpful than calling Kitchen Aid."
SOURCE: Mixer only operates at high speed regardless of the speed setting
the triac solid-state component on the board for the motor speed control is shorted and you need a new control board, unless you can find an outsource replacement triac,most companies won't sell you parts because of liability issues on internal parts of the unit
SOURCE: The kitchenaid speed lever is bent and jammed
Hi TIMDEIST, I hate it when you drop your mixer... they’re really not designed for gravity testing. Let’s see what you can do to get it fixed and operable again. The good news is that this can be fixed quite easily (OK, maybe a little effort) by yourself, if you are a DITY type person, feel adventurous, and your mixer is not under warranty. Be sure you have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website at: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals& Guides> then enter the visitor type “Consumer” and enter the 6 character model number, in this case K45SSW, and then select the file under Parts List (1) K45SSWH0.pdf (341.41 KB) (definitely check to see it this matches your mixer).
Although not providing step by step instructions, the Parts List manual provides an exploded view of the various component assemblies allowing you to see how the mixer all fits together. It is helpful for the disassembly, troubleshooting, and reassembly of your mixer.
Turn to pages 6 & 7, titled “Motor And Control Parts”, and locate Ill. Nos. 1, 2, 3, & 4. #3 is your Switch Lever and stud. If you can’t straighten it out then you will need to replace it. It might also be a good idea to check and see if anything else might be out of alignment due to the sudden stop when it was dropped.
