Appliance: Whirlpool 4 1/2 Qt. Stand Mixer Classic - Tilt K45SSAC-0

Ran at irregular speeds at low setting

Looked at brushes first then played some video from online on how to adjust the speed. Tried that and it did not fix the problem. Went online to AppliancePartsPro and started a conversation with a representative and together we worked on possible fixes. She suggested a phase control board. I also ordered a speed control plate and speed governor just in case. Even though I didn't ask for expedited shipping the parts came in 2 days. The parts order came online with video links to help with the repair. I replaced the phase control board and speed control plate because I had them. The more that I researched the speed governor I realized that it probably was not the problem. I will keep it for backup.

The mixer would turn on by itself

Replaced the speed control handle in various other parts, the videos that are posted with the website are incredible and they tell you exactly how to do it very easy to repair.

No power to a kitchen aid mixer

Trouble shot and found no power going past the phase control board. I did have help and advise from Appliance Parts Pro and it was very appreciated.

My kitchenaid artisan stand mixer would not come on

Easy fix by replacing the phase control board. Plenty of YouTube videos showing how it is done and is really very easy to do.

Kitchen aid mixer turning fast

The mixer was turning faster than normal on level 1 and couldn’t be adjusted by adjusting the screws on the speed control board. I replaced the speed control board but that didn’t work either. Then I found out about the phase control board on YouTube channel. After following your video, I was able to replace the phase control board easily and adjusted the speed to factory specs. Than you!
