This can be caused by a number of things. The first thing to check will be the carbon brushes located on the left and right sides of the unit. Just simply unscrew the caps with a straight screwdriver. Once removed your can clearly see the shape of the carbon brushes. If they appear to have little or no wear and aren't broken, this won't be the cause of this problem. Also take note when you take them out AND put them back in as they willl only fit ONE way. The next thing to check will be the main control at the rear of the unit. After removing the power source, you can also remove the rear access panel. A phillips screwdriver is required. Next after removing the panel, you can now see the main board. Inspect it for any immediate signs of broken or burned wires also check the bi-metal on the control itself, as this will often indicate a faulty board. If however, everything looks good visibly and you still have no power to the unit, the last possible solution could be that the power cord itself has an internal problem. Hope this helps
Thanks
Just a quick amplification. If you have messed with the brushes double check that they replaced correctly. They can fit inside the mixer and still be facing the wrong way. Get a flashlight and check for the little block that holds them in the correct position.
wow thanks!! I just bought a kitchen aid mixer at Goodwill for $25 because it wasn't working. Hubby re-checked the brushes after I read this post and sure enough the 2nd time it turned on!!
I cannot believe that just worked! I called KitchenAid and they told me my only option was to take it to an appliance repair shop. All I did was wipe off the carbon pieces and it started working again! Thanks so much.
Another quick check that might help is simply moving the cord around while it's plugged in and turned on ON THE LOWEST SETTING. If it's a break in the cord (especially likely near the plug or mixer end), the movement might re-establish the connection just long enough to bring the mixer to life. This is especially likely if you move your mixer a lot, and wind up the cord to do it. If it does, that's your culprit, and it will save you time, money, and frustration. Now- just because it didn't come on doesn't mean it's NOT the cord- but it's one quick and cheap way to check it.
Remember Occhem's Razor- "The simplest answer is very often the right one.
Omg...life saver! It was the carbon brushes!

Electrical parts can appear to be good but can still be bad. They must be tested by somebody qualified in diagnostic procedures of electrical problems.
Most likely the cord won't be the problem unless it's where the cord terminates or the cord flexes during use. Constant flexing will cause wire to break eventually and sometimes even the best assemblers in the world can muss up a terminal connection. This can even pass quality control as they only test if the connection is made (one out of the 22 conductors can be made and it'll pass the QC check and the first load that's put on it will blow the one wire that should have been 22 times as strong) and not if it will handle a load. mind you, it was the fault of the assemblers, not the user.
The individual components such as resistors, capacitors, diodes, transistors, and other things failure rates are actually based on the purity of the components that made them and the cleanliness of the room they were assembled in. For a well designed piece of equipment, you can expect the failures to be because of these reasons. for not so well designed pieces... you get the idea.
Last thing you have to consider is the craftsmanship used in assembling the item. Was it designed and assembled to last forever or was it designed right using correct materials but assembled by somebody that didn't even care if all the parts got in correctly.
