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

If your KitchenAid mixer runs at full speed every time you turn it on, you probably have a bad phase board--also referred to as the circuit board. Luckily, Mark is here to guide you through the steps needed to replace the board in your KitchenAid mixer.

My mixer won't turn on. I know the cord is good. How do I check the control board and the phase board before i buy replacement parts. I have an ohm meter to check the switch.

@ptb650 Like most circuit boards you can't test it unless you know what the logic, or output values, of the board should be. You must rely on the symptoms the mixer is having. The most common symptom of a bad phase board is a mixer that will only run at high speed. A bad phase board may also cause the mixer to not turn on. However this symptom could also indicate a bad control board, switch or cord.

I hope this helps,

This is good to know, now that I own one. But here is the trick question... where did you buy a pour guard with the "classic" mixer?

[eReplacementParts]

@TRYER25 Haha. That IS a trick question. The answer is sort of a trick answer, though, too. We purchased the mixer in this video used (with its pour guard and other attachments) so that it would serve as a good example for repairs that would similarly be performed by our viewers on their own used machines. Because of that, we're not sure where the mixer or its accessories were originally purchased or in what combinations.

Thank you so much! My kitchen had flour everywhere due to the flat-out crazy speed of my KitchenAid mixer. Since we couldn't find anyone in our town who was willing to fix it, I was at the point of sending it to Goodwill for someone else to deal with. Glad to see it is an easy fix I can do myself. The information is great and your presentation is exceptional.
