How to Replace the Speed Sensor and Control Board on a KitchenAid Pro 6 Mixer

March 28, 2013
« Previous Article
This article will help you diagnose and repair a bad speed sensor or control switch on your KitchenAid Pro 6 mixer.

The speed sensor and control board work together in your mixer to help the mixer run and maintain specific speeds under variable loads. Basically, the speed sensor tells the control board how quickly it needs to run, whether the load is light such as cream or heavier, like you'd see with a cookie batter.

You probably have a bad speed sensor if you turn your mixer on to the lowest speed and it rapidly speeds up then shuts off. You have a bad control board if your mixer won't turn on or off or if you start your mixer at a low speed and it runs at the highest setting without turning off. Lastly, if your mixer is very slow to reach speed, it could indicate a bad sensor or control board. You'll want to start by replacing the sensor in this case as its both easier and less expensive.

 

Remember to find the control board, sensor or other parts you need for your repair by matching your KitchenAid model number with one on our KitchenAid parts page.

 

Replacing the Boards

1. Remove the beauty ring

Remove the beauty ring by unscrewing the single Phillips'-head screw on the back of the mixer.

 

2. Remove the mixer cover

Now you have access to the four cover screws. Remove them to free up the cover and gain access to the boards.

 

3. Remove the speed sensor

Now you can remove the speed sensor. First, unclip the wire that attaches to the board.

 

Then you can use a flat-head screwdriver to press the tabs at the base of the board to free it from the mixer.

 

At this point, if all you needed to do was replace the speed sensor, you can jump to step 8.

 

4. Remove the control board wires

Before you remove the control board wires, you should note where each goes. We recommend writing directly on the wire lead. Your board will have a word or a color where each wire connects. Just write the word or color on the wire lead to make connecting them later a breeze.

 

Now you can remove the wires from the control board.

 

5. Remove the control board

Unscrew the two screws at the board's base to free the control board from the mixer.

 

6. Install the new control board

Set the new control board into place and tighten the screws. Do not over-tighten the screws as they can crack the control board's mounting feet.

 

7. Re-connect the control board wires

Now connect the control board wires to the locations they were in before.

 

8. Re-install the speed sensor

 Set the speed sensor back into place and snap it into its tabs. Then just re-attach the wire to the board.

 

9. Re-install the cover

Put the cover back into place and tighten the four screws that secure it.

 

10. Re-install the beauty ring

Loop the beauty ring around the mixer, set it into place, then tighten its screw to finalize your repair.
