My kitchenaid stand mixer will not run at slow speed. It runs on the fastest speed when I put it on 1.

Hey Greg, the first thing that comes to mind is that the machine is not tuned correctly. If it runs in slow speed and stops when you move to a fster speed then the speed control switch needs to be adjusted, here is a site that will give you the basics on tuning.

The Kiichenaid mixer has a centrifugal speed governor. I suspect your is stuck. It will need to be disassembled, and inspected.

Sounds like a problem we had years ago. We put too much pressure on the motor by mixing a very thick dough for cookies. It stripped the "gears" and couldn't be used on slow.... it would instantly go to the fastest speed. We had to take it to a reputable appliance store that does repairs on KitchenAid products. I'm still using mine and that has been 15 years ago. It still works great!!

the carbon brush was burned

You can try adjusting the speed control as shown in section 6 of the service manual:

Also remove and clean the brushes as shown in the same manual pg 8 fig. #30.

Call the Kitchenaid service number (1-800-541-6390 in the U.S.). As your unit is still under warranty, and they are very proactive I'm sure this problem will be readily resolved.
