What if when I replaced the speed control, my mixer still will only run for a few seconds and then it shuts itself down? What is the next step that I need to do?

It could be the phase control, or it could be that the governor assembly or associated spring is missing or malfunctioning.

First thing, check the Hall Effect Sensor (part # 9703312) to make sure that it is seated snugly AND properly!  The Hall Effect sensor measures the speed of a tiny rotating magnet and basically tells your mixer how fast it should rotate.  I was experiencing the same problem that many others have described here--my mixer would go really fast no matter what speed I put it on and it would shut off after five seconds. I came to the FixYa site and saw that one solution that seemed to work was to replace the Hall Effect sensor.  So I went to a local hardware store and purchased a new Hall Effect Sensor for about $13.  After I replaced the "defective" sensor, my mixer still did not work.  So, I started experimenting with the three prong orientation of the control board--this can make a big difference. After a little trial and error, I found the correct orientation for the sensor and my mixer worked good as new!  But I was curious to see if the improper orientation was the cause of my original "defective" sensor.  So I put the "defective" sensor back with the proper orientation and THIS ALSO FIXED MY SPEED PROBLEM! There was nothing wrong with my original Hall Effect Sensor at all--it simply was not snugly or properly seated!  I'm not sure how it happened--possibly over time the sensor prongs may have become unseated from the vibrations of running the mixer on high speeds--but my original Hall sensor was not seated properly or snugly.  So before you run out and buy a new Hall Effect sensor make sure that the original one is not only snugly seated but also properly oriented!  If I knew how to add digital pics, I would have put pictures in my comments to clearly demonstrate what I found.  Unfortunately, I am not sure how to do this.   To sum this up: 1. Download the parts information and diagrams from the Kitchenaid site and find the Hall sensor (part # 9703312).  2. Make sure that the Hall sensor is firmly attached on both ends.  The actual sensor should be located next to a tiny magnet and this end needs to be securely seated.  And the other end of the Hall effect sensor has three small prong holes which also need to be firmly and corrected seated to the control board! Bottom line, my mixer is working like new and I put the original Hall Effect sensor back in the mixer. I'm going to hold on the new one as a backup...you never know.

Pull the back off and there will be two screws at the top of the Speed Control Plate and a 3rd screw at the bottom. Tighten the top two screws down. [email protected]. Let me know if it works.

I would recommend that you first check the Hall Effect sensor which determines the mixer’s 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 mixer 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 snug and tight. Guess what?  My original sensor also made my mixer work!  There was nothing wrong with the original Hall Effect sensor except that the connection between the control board and sensor was not tight--unfortunately I didn't check the connection before I decided to buy another sensor. My guess is that the connection between the control board and the sensor probably loosens or comes undone over time from use and vibrations. To fix your problem:
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 gear case cover.
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 is correct.  It's difficult to tell which way the sensor should be connected because the control board has three prongs and the sensor can attach facing up or down. After you've made the connection, run the mixer. If it still doesn't work, disconnect the sensor, reconnect it with the prongs facing the opposite direction and try it again.  I actually found the right sensor orientation through a little trial and error.  But 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 about 10-15 minutes to perform.
6.  Finally, use your common sense and make sure to unplug the mixer before checking, connecting or disconnecting anything.
