Has power on but doesn't run
If you took your brushes out to check them then your mixer will not work if you put the brushes back in the wrong way even if you fixed the original problem. the beveled side of the brushes must go back into the brush holders a very specific way/direction because the brush holders have a pinched corner on one edge that allows the brush to slide past and to make contact with the armature. if you are sure that the brushes are in the correct way lets proceed. (If not get a flashlight and look inside the brush holder for the pinched down corner and reinsert the brushes the right way)
fist the basics, I know it seems dumb to even think this but ... well you know.
1. check the outlet you are using for the mixer to see that it has power.
2. The outlet is hot, look at the rar top of the mixer you will see a small "Phillips Head" screw. take it out. and lift up and out at the same time to remove the the rear motor head cover.
3. take a moment and look at what you see. now look at the cord that you use to plug the mixer into the outlet. follow it back into the mixer head and you will see three wires. Green = ground and it is attached to the mixer frame with a #3 Phillips screw, leave it alone. the other two wires, one black and one white attach to what is called the speed control board by means of two flag style connectors. Are they attached? Or have they or either one of them come off?
4. if they are attached to the flag terminals, then get a multi meter and check for power between the terminals. the black test probe goes to the black lead on the mixer terminal, your red test lead goes on the white flag terminal attached to the mixer. personally i would disconnect these two leads before I tested them to avoid any safety issues with the mixer. If ther is no power to the terminals when you p,lug the cord into the wall then the cord is bad. Order one and replace it. you could also test the cord another way by checking for ohms resistance and you won't have to plug the cord in at all. Ohms testing is safer.
5, if the cord is good then the next thing to look at is the phase control board. that is a small computer style board above and behind the big black and copper board with 3 screws in it. It has 4 wires coming out of it. You probably have no real way to test this unless you are familiar with electrical :Bread Board" circuitry. i usually just carry a new one with me and replace it. It's faster.
6. If the system still does not start I remove speed control plate/board,The black and copper one. (there is a spring attached that will have to be removed, if you let it snap back into the machine you will have to dismantle the entire motor head to dig it out, so hook a cloth under it's clip that will hold it and keep it from snapping back into the mixer). Now install a new spped plate and test again. if you still have no power there are only two electric problems left one is the armature and the stator which are the two components that make up the motor, but it will require a complete tear down to replace. I have never had a motor go out. the problem is usually the cord or brushes. Let me know if this helped. If not we can post a location to the service manual and parts list for your mixer.
