I replaced three parts since I was doing the repair anyway and would have the mixer apart. The Phase Control Board, the Speed Control Plate and the Speed Governor. I was not that much more to replace all the parts, and I wanted to get it right the first time.
The videos that accompany the parts when you look them up are extremely easy to follow along and I was able to quickly disassemble, replace and make all necessary speed adjustments.
I highly recommend Appliance Parts Pros as I got my parts quickly as well.
Great job!
