While using my mixer for grinding some shrimp and vegetables at high speed (10), it started slowing down to about a 4 or 6 speed setting. I thought that the grinder was slowing it down so I removed it to see if the speed picked up. It did not. I turned it off for a few minutes, then turned it back on with the grinder attachment. At first, it started off at slow speed while still at #10 setting, then it slowly picked up to a fast #10 speed. What's the problem. Does the brushes have to cleaned or replaced or is there an electronic speed module that's deffectice?
I'm not quite sure about this answer but it occurs to me that it could be the governor. It sits at the back end of the armature and as the speed control is slid to faster speeds the governor moves away from its rest position pressing against the control plate. If the governor's pivots were to be binding, even slightly, it would explain the symptoms you are describing. A service manual can be found at:

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!

depending on the model there is a round cover on the front of the mixer. Detach it to expose the secondary drive connection. Depending on what you are connecting to it you need to connect to the drive port and secure the accessory so it is stable. If you need instructions google kitchen aid and ask them for a manual.

I would recommend that you first check the Hall effect sensor which determines the speed. I had this exact problem and I actually went out and bought another Hall sensor for about $13. I replaced the original sensor and made sure that the connection between the sensor and control board was nice and snug. My blender worked as good as new! But I was curious to know if my original sensor was defective so I put it back in mixer and again made sure all of the connections were tight. Guess what? My original sensor also made my mixer work! There was nothing wrong with my original Hall effect sensor except the connection between the control board and sensor was not adequate--unfortunately I didn't check the connections before I decided to buy another one. My guess is that the connection between the control board and the sensor probably loosens or comes undone over time from use and vibrations.
1. Download the mixer parts and diagrams from the Kitchenaid website to see what the Hall effect sensor looks like. 2. You'll need a phillips head screwdriver to open up the mixer. 3. Make sure that the connection between the control board and sensor is absolutely tight and snug. 4. Also, make sure that the orientation of the sensor connection between the control board and sensor is correct. it's hard to know which way the sensor should be connected because the control board has three prongs and the sensor can attach facing up or facing down. If, after you've made the connections, the mixer still doesn't work. Disconnect the sensor and reconnect it with the prongs facing the opposite direction and try it. I actually found the right orientation through trial and error. By going through this trial and error, I also had my Eureka moment when I realized that the original sensor probably would also work if it were reconnected with correct orientation. 5. This whole process probably takes less than 10-15 minutes to perform. 6. Make sure you use common sense and unplug the mixer when making connections and such.

Hi Gail. Kitchenaid no longer has a Parts List for your model. This means that they consider it obsolete. Do an Internet search for parts. You may get lucky. Good luck!

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.
