Whirlpool W10870869 Field Assembly OEM Part

God Bless Youtube! Searched "replace motor in Kitchen Aide mixer" and found an excellent tutorial on the subject made by AppliancePartsPros.com. Followed the instructions with my smart phone and purchased a new motor and brushes. Fixed the $500 mixer for $50.. Runs like new but now have to change the color per her request. Excellent company to deal .

First thing I've noticed was a bad smell and slightly slower speed. Next thing I've checked the brushes (they were burned on the edges) that usually guide toward the burned windings on the armature, sometimes even field. Since Appliance Parts asking $13 for the field assembly I've decided to change both Armature and Field. Thanks to Appliance Parts for surprisingly fast shipping (received both parts next day).

Tested the motor for continuity and realized that the field was broken. Sure enough, it was melted and burnt on the bottom side. So bought this part and replaced it which fixed the problem. The only thing left to do is calibrate the motor speed but I need another tool for that. In the mean time, so happy that a $15 part fixed my $200 mixer. :)

I ordered the armature and field-asm cause I did a test on the armature by connecting it directly to the power line and did not have any movement. Upon changing the armature and assembling the brushes, I realized one of the brushes was getting held up. I opened up the edges of the brush holder and that did it. I knew nothing seemed wrong with the parts I took out so I concluded that was the problem because I had just bought it, used it only twice and it stopped working.

This was a big job as you are basically taking the mixer down to its bones. Thankfully, the you tube video was extremely helpful and the project went smoothly. Just make sure to have food-grade grease on hand before you start. I tore the entire mixer down and re-greased the planetary gears up front as well as replaced the motor assembly. This mixer was handed down to us by my mom, it is probably 25+ years old, but runs like new now.
