Question about KitchenAid KSM103 Professional 5 Series Stand Mixer
My mixer is a Kitchen Aid Professional 6 quart series I bought it in Nov. 2002. It never did start in the "Stir" position. I should have taken it back to Linens and Things 10 years ago. Warranty is expired now. It is Model number KP2571XWH. Serial number WM392-1855. I have to slide the control knob to 2, 4, or higher to turn on the mixer, then slowly back slide it to the desired speed. I only use the mixer a few times a year, but it is alway frustrating. what might be the problem and how can I fix it myself. The nearest "authorized dealer" is in another state?
SOURCE: mixer speed turned erratic!
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. BTW the part number is 9703312. 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 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.

It shouldn't do that, and I really doubt there's anything you can do about it other than to have the defective part replaced. It sounds to me as though there's a problem with the control mechanism. If the machine is still under warranty, contact Kitchenaid to see about getting it repaired or replaced. If not, get the name of a local shop that repairs Kitchenaid mixers -- from your description of the problem, the mixer is nearly unless in its current state.

Looking at the diagram here:
You will see the motor controller Item Number 19. Looks like a pretty simple taks to remove and replace it. there is also a hall effect sensor Itme Number 24 which monitors the motor speed. That might be faulty as well, but my best bet is the controller.
Unfortunately the parts list does not specify the part number for the controller so a call to Kitchenaid is probably required.
