Mixer worked fine last time I used it (a few months ago). Now it won't start (nothing - no activity at all. Took it apart and found nothing out of the ordinary. transmission works smooth when disconnected from motor. Removed, checked, cleaned and reinstalled brushes. Replaced power control module - nothing doing. My next step is replaing the motor, unless someone else has an idea. The info I've seen on the hall field sensor impies this is a speed control issue, and I have no power at all. When I took the motor apart I checked for continuity across and amongst the contacts on the rotor (where the brushes contact). I was thinking that there should be no continuity between adjacent contacts but there was (no resistance at all). That is what makes me think it's the motor (lightning strike while plugged in but not turned on ?). There is no smeall, no marks or anything indicating what could have happened. Any help would be appreciated.

Apart from checking a fuse, there is little more you can do. Did you notice a loss of power or burning smell the last time you used this? What make and model you have may help others identify a known problem with your machine.
You need to either re-time the speed control switch at the back or replace it. If it worked great before then it is just an adjustment to get it back to running correctly. YouTube viseo available for timing the switch
Yikes!!!! Can you tell us what you were making last time you used the machine? Do you do pizza and other doughs a lot. The KSM150 is a 325 watt mixer with lots of power so; 1 first lets go back to the outlet and try anything that can show fast results like a hair dryer to test the outlet.2 The cord from the mixer, do you unplug it by pulling on ti? Or do you use the plug itself when unplugging. Do you have and know how to use a volt meter. If yes to both 3 Remove the rear cover and you will see a black and copper plate with a whole bunch of connectors on it. the left two bottom black and white terminals are the power for the mixer, turn the mixer on and test the terminals to make sure the machine is getting power, if not replace the power cord. You will have to open the machine and take it apart somewhat to replace the cord. 4 it could be the speed control plate itself (Most likely) there are three screws on the plate in an upside down triangle, turn the one on the bottom left a little bit while the mixer is on if it is the adjusting screws it should start again with less than a half turn. 5 Look at all the terminals to the speed control switch and make sure that they are connected if any one of them has come off then the machine won't work.
There can be other problems but this fix is the most common. Let us know if this does not work and we can go into it a little more in depth.
If you leave the machine on for a minute or more does it start to smell (burnt smell or hot electric) If you have a warranty (still within the first year of purchase ) get in touch with Kitchenaid they will send a new mixer with out question. If you are out of warranty then we can fix it, one step at a time, or you could take it to an authorized service center, if you live close by to one. Let us know.
Hi. Since I can't tell how much you have taken apart, I'll start from the beginning.
Remove the silver band, remove the top cover. At the top front of the mixer locate the transmission housing. If it's plastic, inspect it carefully for cracks around the screws and the body of this housing. If you find cracks, you have found the cheap plastic part that kitchenaid still installs in new mixers, and the cause of your trouble. They know that it's substandard but don't care enough to place a recall notice on this part. It may not please you to know that their replacement part is METAL like the original part should have been. "For the way it's made"! Indeed!
If you intend to repair the mixer yourself, go to kitchenaid's website, enter your model # and locate the parts list for your mixer. Download the drawings, they will assist you with your project.
Be sure to tell kitchenaid what you think of their cheap plastic part.

I used to live in Mtn. View on Bryant St. next to the P.G.&E office, great town.
I have had appliances go as long as twenty years and never had the brushes go out, but it sounds kie that is your problem alright, this is very unusual I would contact Panasonic and see what they will do for you there is usually a one year parts warranty on small appliances, call them you have nothing to lose. I would call this a factory defect.
