I have a KitchenAid pro mixer that is making a slow clicking noise. It gets faster as I turn up the speed. I first noticed it after replacing a stripped worm follower gear. It sounds like it's coming from the motor. I have checked/cleaned/and re-greased all the other gears several times, and I am confident they are all working properly. Everything looks fine. As far as I can tell. It is not a huge clicking noise, but almost sounds like the fan is hitting something as it goes around. Is this something I should worry about? If I should worry about it, how do I fix it?

  • Did you reinstall the motor-brushes in the correct orientation? Brushes tend to wear asymmetrically, and can produce a clicking sound if you get them in wrong. May 15, 2012 at 0:40

    Is it cyclical with the movement of the paddle/whisk? Is it possible that you need to adjust the position of rotating element over the bowl?

  • I've done the same thing. I changed the worm gear and the worm follower gear and now I hear a clicking sound and I know that its all in place properly.

Does it only do it under higher load? Mine clicks a little bit when kneading dough, and I determined that it was actually the bowl moving a bit. I have a lift-bowl model, but it could be either that or the hinge on a tilt model.

If it is under load, try pushing on the bowl to eliminate movement. If it happens even when empty, this isn't it.


Happened to me after replacement of lower gear housing. It's caused from having the two motor mount screws too tight. I realized that could cause a bit of stress on the harmonics of the motor operation. Loosened and reinstalled just barely over a light snug, that did the trick.


After I changed the nylon gear, I missed a small piece of the striped nylon gear that was hiding in all the grease. After running it for a few seconds it started clicking. I tore it down and spun the gear with a punch until i found a spot that would catch, and found 2 VERY small pieces of the stripped nylon gear in the teeth of large planetary? gear. After removal it's running like new. If it happens again i will change the grease, and find the piece in the gear. Very small, hard to see pieces in the back of the gear teeth.
