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

My mixer turns on and the paddle turns, but when I add any ingredients to the bowl, it stops turning!


sorry to say but you have an inside gear problem, not catastrophic in and of itself, but it will require a full tear-down, the worm gear is either worn down or stripped, It is made of nylon and its supposed to wear out or give out if there is a problem. It appears that there is enough gear left to turn the paddle but as soon as you have any load on it well not enough tread left to keep spinning the paddle. Service center will cost from $150.00 to 200.00 depending on where your nearest KA service center is (that includes shipping) If you are good with mechanical stuff you can do it yourself for about $50.00 dollars. There are sites on the web that will show you how and your parts list from the kitchen Aid site will show you what you need to order off of ebay to repair it.

KITCHEN AID MIXER K5SS has a banging noise when turned on how would I find out how to fix it ?


You will need to open it up and inspect the brushes carefully. Look for a little copper wire, this wire needs to be firmly attached to both the brush and the little disc at the other end of the spring. Clean the brush out with a can of electric cleaner to free any dirt that has built up around the gears.

Where does the speed control spring go on a kitchen aid k5ss


Hi NG345, Merry Christmas and Happy New Year! It sounds like you’ve got the right part to fix your mixer, now you just want to install it correctly. The good news is that your replacement spring can be installed quite easily (OK, maybe a little effort) by yourself, if you are a DITY type person and feel adventurous, and your mixer is not under warranty. Be sure you have the Parts List manual on hand, too. If you're lacking one, you can download a PDF version from the KA website: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case use KSM50P (Your K5SS mixer falls within this manual), and select the first file KSM50P.pdf (438.31 KB) listed under Parts List (4) and then check to verify this matches your mixer model.
Turn to pages 6 & 7, titled “Motor And Control Parts”, which provides an exploded view for the disassembly and reassembly of your mixer’s electrical components, along with all the parts. You’ll want to focus on Illus. Nos. 1, 2, 3, 4, & 5; Pivot screw, Spring washer, Speed control assembly lever, Control plate spring, and Speed Link & Cam, respectively. Your speed control assembly is attached to the bottom of the top part of the mixer’s head (or Illus. No 1, Gearcase Motor Housing, on pgs 4 & 5).
Finally, here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer. The mixers displayed in the links are different KA models, but the principles are the same.
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, should you decide to go that route.
If you feel this repair is beyond your capability, then I would seek out a local small appliance repair shop in your area. KA Customer Care can give you names of local KA authorized repair shops in your area, but you can also do an online search to supplement what KA may provide you. Call to explain your circumstances and find out their hourly rate and get an estimate of what they think it would cost to repair your mixer. Also, always obtain three or more estimates – do some comparison shopping.
Good Luck. I hope this helps. Howard, Burke, VA

I have disassembled my K5SS Kitchen Aid mixe with all gears removed in order to solve its electrical problem. When I plug in the motor and move the speed lever, there is no movement or sound of the motor...


Unless it sits at the back of the motor behind the vent cover. I couldn't find one anywhere on ours either. Check the motor brushes for broken or badly worn carbons, or collapsed springs. It could be a broken wire at the plug end or something wrong with the speed switch. Some strategic voltmeter sleuthing is required. Try turning the motor shaft while the power is on. It may have a dead commutator segment.
