How to Replace the Circuit/Phase Board on a KitchenAid Stand Mixer

  For this repair we used a KitchenAid stand mixer. The circuit boards differ by mixer type so before you begin the repair, make sure you find the right board for your mixer by using our KitchenAid product locator.
Replacing the Board Before you remove the board you should note where each of the four board wires goes. This will save you a bit of time, though KitchenAid does label the wires in case your forget to check them.

1. Remove the rear cover

Remove the screw that secures the rear cover. Then you can remove the rear cover.

2. Remove the phase board screw

The phase board is fastened by a single screw. Remove the screw to free the phase board.

3. Disconnect the wires

Use a pair of needle-nose pliers to disconnect the wire connections.

4. Remove the board

Now you can remove the board from the mixer. It fits snugly, so you will most likely need to tilt it up over the control board to slide it out.

5. Install the new board

Now you can install the new board. You will need to slide it in and down to clear the control board.

Then you can set it in place and fasten the screw.

6. Connect the wires

Connect the four wires to the mixer. If you forget where each wire goes, KitchenAid labels them as follows: RW for the red and white wire, RD for the red wire, BK for the black wire, and BL for the blue wire.

7. Replace the cover

Now just replace the cover and fasten the screw to finalize the repair.
