Question about KitchenAid K5SS Heavy Duty Commercial Stand Mixer
Was not working, checked brushes, they are good, pulled white wire from power & red wire to coil loose, clamped them together, hit the switch, machine functions in all speeds, odd..... plugged everything back together, now it runs fine until..... one side of the governor assy. comes loose, enough that it rubbed away part of the circuit board, is it a defect in the governor causing it to come loose or is it just running too fast? I did notice that bypassed, the machine will still function at all speeds without the circuit board even connected, what is the main purpose of the board?
The governor should move back and forth as the speed control goes from speeds 1 through 10. It's purpose is to push on the control plate in order to obtain the different motor speeds.

I have the same mixer and I believe your problem is the governor that is on the back of the motor. You can figure it out by downloading the repair manual here:http://store.mendingshed.com/kitaidparts.html The manual has all the info you need; including a troubleshooting section. The governor is availible from the the same site here:http://store.mendingshed.com/kagovernor.html What tipped me off on my K5SS was looking at the governor as it ran and I could see it moving back and forth; not steady like it should. Good luck!

Pull the back off and there will be two screws at the top of the Speed Control Plate and a 3rd screw at the bottom. Tighten the top two screws down. firstname.lastname@example.org. Let me know if it works.

looking from the rear of the mixer, insert the LEFT brush so that the champfer is facing down. Then insert the RIGHT brush so that the chamfer is facing up. that fixed the problem for me.

Hi, KIMAMABELL, While working on your mixer 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 at: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case, KSM90P, and select one of the files listed under Parts List (check to see it 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. Locate Illus No 32, Brush holder that includes #18, 20, 21, 22, 23, and 31 which is the brush holder and brush & Spring assembly respectively.
The brushes need to be installed so that they both seat correctly on the armature's commutator and it’s possible when you reinstalled them, one or both brushes were turned incorrectly.
The illustration below shows the correct orientation of the brushes and should allow you to reinstall them with confidence.
Here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer for your future referennce.
Good luck! I hope this helps. Howard, Burke, VA
