I just did this last week!
1 Unplug Mixer 2 Remove screw on TOP of mixer body, at back. 3 Remove rear cover and paper-gasket thing (its not the end of  the world if you end up tearing it a little). 4 the phase control (little circuit board w/wires) is at the top (you  should see it very easily) held on by one screw, remove it. 5 when the circuit board is unscrewed, disconnect all the wires  that are connected FROM THE CIRCUIT BOARD to the  black control plate (NOT all wires-there should be 4 left on  the control plate at this point).  you don't need to  remember where all the colors go as the control plate is  labeled->but looking at them and making sure you  understand the abbreviations would be beneficial  (BK=black, BL=Blue RW=Red&White W=white R=red etc.   6 install new phase control (screw), either buy new thermal  grease (used to keep the board cool->it transfers heat to  the mixer's housing) or try to salvage what you can from  the old one. 7 connect wires, paying attention to labels. 8 reinstall paper gasket, then cover, then screw to hold on back- cover.

SOURCE: kitchenaid k45ss won't turn on

if you remove the top you will find a tiny fuse wrapped in a black band on the left side from the back. It connects two white wires which power the top-side motor brush. Most likely this needs to be replaced. You can check by bypassing it with roach clips or a copper wire. Unplug the machine first and be careful!

SOURCE: k45ss kitchenaid stand mixer, i took out the brushes

jrichards - I hate it when that happens! It seems that power is not getting to the armature from the brushes so I would suspect that one or both of the brushes is (are) not seated properly. Did you remove the brushes to replace them or were you just inspecting them? I'd suggest removing them again and making sure the contacts are facing in the right direction to contact the armature. The concave contact face should be resting completely on the armature. If you've turned it 90 degrees too much, it wont' seat properly. I hope this helps... Howard, Burke, VA
