Introduction

Replacing the carbon brushes might sound intimidating, but you don't even have to take the mixer apart to get to them.

Unscrew the brush cap on each side of the mixer using a flat head screwdriver.

  • The brush caps are on springs and will want to fly out, so unscrew them carefully.

Pull out the motor brush from the brush holder on each side of the mixer. One corner of the motor brush is flattened at a 45 degree angle. Check the orientation of the motor brush by looking inside of the hole through a flashlight.

    • In this case, we inserted the new brush with that flattened corner facing the upper left corner of the brush holder.

Important!!!!!!

Please check the real orientation by looking inside of the hole through a flashlight. The flattened corner is not always face upper left . At least for my 5 quarter machine bought in 2008. I am installing the two brush using the “upper left ”and found that it is not spinning. I even suspect the phase control board. Then I figured out the correct orientation by looking through the square shaped hole, there is a tiny copper block stays at a corner. Need to put the flattened corner facing this corner.

Replaced Circuit Board and Phaser control, and the 2 brushes. Nothing. then I saw this article. Yep, had a brush that I needed to spin 180 and face bottom right. Works great now. Thanks

That first comment saved my butt. Glad I found it early in the process.

Thanks for all comments! I cleaned my machine and panicked when it wouldn't start afterwards. So I searched and couldn't find a solution... so I searched under "won't start" and found this info. An answer to my prayers! For those, like me, you have to scrutinize the very end of the hole and you'll notice that one corner is a little different, a little thingy that can be hard to miss. That is where you want the flat corner of the part to go. It took me a couple of tries but I finally got the correct orientation and it started. Yay!

Hi Dennis, it is mentioned above " Be sure to insert the new brush with that flattened corner facing the upper left corner of the brush holder." However, on my mixer only one brush must be aligned upper left; the other brush must actually be aligned down right. Look into the slots with a flashlight, you will see which corner has a small metallic piece, or "stop". That's the corner you must align your brush on. Hope this helps..

Hello patfat, you are exactly right on those brushes. I been working on this used mixer I got off Ebay for 56 dollars. It ran but I tooK it all apart and cleaned and painted and got some new parts and it would not start. The brush thing is right, one brush upper left and the other one bottom right. I got her fired up and it looks like banana nut muffin time again. Heres one for you.....! You the boss.....

OMG OMG OMG! You are an angel! I scored this brand new looking Kitchenaid mixer at a Goodwill for $3 dollars. Said whaaat? I grabbed it but when I tried it, it would not turn on. I didn't care, I figured I would fix it myself. I followed your instructions and VOILA! It works like a BRAND NEW Baby! LOVE IT! Thank you so much for such easy instructions!

This information was crucial to fixing my mixer. My husband replaced a broken worm gear and my mixer STILL wouldn't start. With the aid of my cell phone camera, which allowed us to increase the size of the photo, we were able to determine which side was upper left and which side was lower right. And when my mixer came on, I yelled and jumped up and down. Thank you!

How do I get the motor brush out if it gets stuck?!

Thank you !! I had given my mixer a thorough cleaning, including taking off the screws. Next time I went to use it, it wouldn't turn on (: Sure enough, inserting those pesky brushes correctly did the trick. Good for another 25 years (although I really want a candy apple red one).

I cannot wait to tackle this fix. I have a Kitchen aid Stand mixer that I have had since 1983. I did not use it that much but it quit in the late1990s. It has been in the closet ever since. My husband has tried to get me to throw it out several times and I refuse. I cannot wait to fix it. Thank you so much, I hope this is my problem.
