20 Most Recent KitchenAid K5SS Mixer Speed Control Plate Kitchen Aid Questions & Answers

Take the back cover off, remove the wires. Unclip the spring from the bottom of the plate, don't let it fly back inside the housing. Unlock the 2 screws at the top and undo them. Fit the new plate, each screw 8 turns in to start with. Hook up the spring, put on the wires where they came from. Start machine on speed one, and adjust the top screws evenly to give the planetary 13 to 15 revolutions in 15 seconds. Lock the screws up with the lock nuts. The screw at the bottom is then adjusted so that it gives a slight speed increase when you enter speed 2 from speed 1.

Could also be a broken wire to the control plate. It's not very often the plate itself. Just looking in there while operating the lever may reveal something. The shaft at the bottom that moves the plate closes a set of points to start the mixer, maybe the points are loose and not closing when they should. Just be careful operating it with the cover off and alive.

If your mixer only runs on high speed there are 3 things that can cause that. The first thing to check will be the speed control plate, Remove the trim and end cover on the mixer, the first thing you should see is the speed control plate, this has 3 screws on it, try adjusting the top two screws 1/4 turn, this should slow the mixer down, do not over tighten. Also check to see if the control plate spring is unhooked. If the spring is unhooked, attach to bottom of the control plate, and squeeze the spring end.
If this does not fix your mixer, check the wiring of the mixer, you can locate a wiring diagram on the last page of the service manual.
If the speed control plate is adjusted correctly and all the wiring is correct it will be your speed control phase board. You can test the speed control phase board to see if it is shorted. With the line cord disconnected, pull the t-b ar contacts to open, and insert a piece of paper between them so they cannot close. Reapply power-the mixer should just run or buzz trying to run. If it operates at full speed, teh phase control board is defective and needs to be replaced.
Here is a link to the service manual: http://lib.store.yahoo.net/lib/mendingshed/kitchenaidservicemanual.pdf
This will aid you in taking the mixer apart, troubleshooting and putting it back together, remember the wiring diagram is the very last page.
Thank you,

Yes and isn't that the dumbest design for something like that. 3 screws when older models had 4 and no locating pegs where older models had 2. Great progress Kitchen Aid.

Make sure that the carbon brushes are free moving in the holders under the black caps, one on each side. Note that the brushes are "keyed" so that they will only fit and work one way. There is a blocker at the bottom of the brush holder that is to be lined up with the corner of the carbon brush that's been shaved off. Use a torch and remember to unplug the power before you start. Next thing to look at are the wires and switch contacts underneath the back cover.
