KitchenAid Classic Mixer K45SSWH Circuit Board Replacement

Difficulty

Easy

Steps

Time Required

10 minutes

Introduction

If your mixer is only working on certain speeds, you might need to replace your circuit board. Don't worry, follow this guide on how to replace the circuit board.

Tools

Step 1

Using a Phillips #2 screwdriver, remove the 10 mm screw from the top of the back cover.
The rear cover is now completely free from the mixer.

Step 2

Using a Phillips #1 screwdriver, remove the 9.5 mm screw holding the circuit board in place.
The screw may be hidden underneath the seal.

Step 3

Using pliers, remove the connections for each of the four wires connecting to the circuit board.
Remember which color wire corresponds to which connection or take a photo. Improper placement will not allow your mixer to turn on.

Step 4

Grab the four wires away from the circuit board.
Tilt the board back to remove it.
If the board won't come out with some wiggling, you may need to loosen the two screws at the top of the control plate. Mark the top of the heads and loosen them 5 complete turns, without removing them completely. You may need to loosen the locking nuts.

Wo bitte kann ich eine neue Leiterplatte bekommen?

Bei mir geht die erste Schaltstufe nicht und ich muss mit dem zeiten Gang starten, was mir die Zutaten aus der Schüssel schleudert.

Danke für eine Antwort.

To protect the board, be sure to put heat-sink compound on the back of the new circuit (phase) board to ensure proper heat transfer to the housing.

If the mixer gets locked up, can it cause the circuit board to go bad? Mine jammed due to a bad gear, now the motor won't run. I have juice to the board. Any suggestions?

hallo,

meine KidchenAid sagt seit heute nichts mehr. Es hat einmal geknallt und die Sicherung ist raus geflogen. Als ich den Elektronikdeckel hinten aufgeschraubt habe kam mir eine kleine Rolle auf einem Federdraht entgegen geflogen. Ich weiß nicht wo sie hingehört. Kann sie hier auf den Bildern nicht entdecken. Kann mir jemand sagen wo das Ding hingehört?

Danke Christian

Long time ago but did you check the shaved off edges and aligned it properly into the holes? This solved my issue :)

Dear all,
I am facing the same issue as all users. My wife was mixing and requested me to repair it. So I removed the cover and the carbons to have a look inside and changed nothing. After reassembling everything nothing happens. Very strange. Anyone any ideas what went wrong or what to consider when re-assembeling it? TIA! BR, John

Nadine Heller -

Alright. It is very important to align the brushes/carbons correctly in to the holes. Then the machine will run again without problems.... :)
