Hello,
There are a few reasons this might happen from ugly to easy lets start with easy and work to ugly.
1. check the outlet you are plugging the mixer into...I know I know but it does happen
2. The cord on the mixer might have a bad connection or one of the flag terminals may have come loose or broke, remember all metal fatigues. If you know how to uses a multi meter an easy check by removing the rear cover and check the power on the contacts from the end of cord that plugs into the wall and then goes into the mixer, you can check by Ohms testing (safer) or by live connection to the outlet in the wall.
3. The brushes on the mixer, one or both may have reached end of life, easy and inexpensive fix. They are under the big plastic screw covers that you see on the side of your mixer. BTW they can only go in one way and if not replaced correctly the mixer will not work even if you have a brand new mixer.
4 The mixer may need a new speed control plate rather more involved because you have to speed tune the mixer after it is replaced but inexpensive and can be performed by anyone from the rear of mixer. BUT!!!! The speed control board may not be bad but only that the mixer needs to be speed tuned.
5. It may be a phase control board gone bad, it is behind the speed control plate, again it can be replaced relatively easily but you also will have to speed tune the mixer and it will be a double digit cost on the part ($25.00-$30.00 unless you go to the internet and search sites, you may find on eBay for 12-15 dollars plus shipping.
6. We are now entering the ugly phase. the items above are all the electric problems that you can fix easily and inexpensively. The next requires a complete tear down of the mixer to replace the Stator and or Armature (the motor). You can do it but it will cost around $60-$70.00 dollars for the motor and then $6.00 for a new gasket which you will need as soon as you open the motor head. Some peeps just re-use the old I would not.BUT!!!!
7. The gears may have stripped while you were using the machine on high and has frozen up so that when you turn it on it won't work. If that is the case then the mixer will have to have the gears and grease and gasket repaired. Gasket=$7.00, Grease=$17-$24.00, it only comes in quarts and you get 30 ounces but only need 6 for a re-grease, Gears, there are 3 and they run between $10.00 for one and up to $30.00 for the pinion tower. No way to tell from the info you sent.
I have been fixing kitchenaid mixers for a while and I am only now replacing my first motor. So I think it is an easy to intermediate fix, DIY could spend 3 hours doing and spend $30.00 bucks on parts. The ugly $150.00 to $175.00 and I would recommend a service center do the motor because they will check all gears repack grease install new gasket and do a speed tune when they fix it.


Kitchen aid mixers are great and sometimes need a little TLC and they will last for years and years. If you could explain further exactly what happened during the speed run up and what you were mixing and what model and serial number (can be found on white sticker under base of mixer in the base cavity). then I may be able to narrow down the repair / fix path. If this helps at all please let us know we like to hear if we are able to help.

Check your Brushes  or bushings or whatever there called ) those little black things on the side of your mixer above the speed selector and the up/down switch) Check to see if they have started to wear down then i recommend taking it in for service. Good Luck!

SOURCE: My Kitchenaid K5SS 300 watt standing mixer launches into the highest speed regardless of the speed ....

I had a similar problem where the mixer would also go to fast speed right away. On the back at the top was a screw that was loose. After tightening this screw I had 4 speeds but no stir speed. I unscrewed that screw and a bolt fell out. This bolt went to threads on the inside of the area covered by that back plate. I put that bolt back on and tightened it and the corresponding one on the other side and wala the mixer works perfectly at all speeds. Hope it helps. Make sure mixer is unplugged before attempting anything like this (wires are exposed when the back plate is removed - some kind of flexible circuit board).

Hi Gail. Kitchenaid no longer has a Parts List for your model. This means that they consider it obsolete. Do an Internet search for parts. You may get lucky. Good luck!

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

It sounds like something is obstructing it or the lever is bent. You will need to take the head apart to investigate further.

We have a K45SS mixer problem. When it is on the lowest setting it hums and the beaters barely turn. The next setting up has a noise but the higher speed settings work just fine. What is the problem?

the lower setting is for stirring. this is a high quality machine that is made to take a beating. you are just hearing the motor wind up. think of it like a jet engine starting, its made to run its smoothest at high rpm's, so it sounds funny at low rpm's but nothing is wrong with it.

Make sure that the Motor Brushes are not worn out and making good contact with the Motor.
Adjust the mixer speeds (if necessary):
Remove the screw holding the End Cover and locate the three screws from the Control Plate.
All three (2 top left and right, and 1 bottom) must be adjusted.

1. Loosen the lock nuts enough & Turn the 2 top screws clockwise until they cannot be turned
anymore. Leave the bottom screw alone for now.
2. Use a dab of white paint or paper whiteout to mark the positions of the Phillips screws.
3. Plug in your mixer and Set the speed selector to "Stir".
4. Turn each top screw One full turn couterclockwise (alternating between Left and Right)
Keep making one full turn at the time (for both left and right) until the motor starts running.
5. Put your hand near the Agitator shaft and allow it to brush your finger slightly. Use your
watch or clock and start counting the number of times the shaft touches your finger in
60 seconds. The correct count should be 60 RPM (Rounds Per Minute). If it is less
or more than 60, give each screw 1/4 turn counterclockwise or clockwise and start counting
again. Now tighten both lock nuts.
6. Set the speed selector to "6" and turn the bottom screw either clockwise or counterclockwise
to achieve a speed of 180 RPM.

For your reference, the planetary RPM's for the 5-qt. tilt-head Artisan Stand Mixer are as follows:
Stir speed - 60
Speed 2 - 95
Speed 4 - 135
Speed 6 - 180
Speed 8 - 225

First, you may want to adjust the mixer's speeds:

1. Loosen the lock nuts enough & Turn the 2 top screws clockwise until they cannot be turned
anymore. Leave the bottom screw alone for now.
2. Use a dab of white paint or paper whiteout to mark the positions of the Phillips screws.
3. Plug in your mixer and Set the speed selector to "Stir".

watch or clock and start counting the number of times the shaft touches your finger in
60 seconds. The correct count should be 60 RPM (Rounds Per Minute). If it is less
or more than 60, give each screw 1/4 turn counterclockwise or clockwise and start counting
again. Now tighten both lock nuts.
6. Set the speed selector to "6" and turn the bottom screw either clockwise or counterclockwise
to achieve a speed of 180 RPM.

Speed 2 - 95
Speed 4 - 135
Speed 6 - 180
Speed 8 - 225
Speed 10 - 280

Second, if the mixer won't run:
Remove the Control Plate Assembly (36), the Phase Control Board (39)
and the motor Governor Assembly (35). Inspect for loose connections,
burnt or damaged components. If they seem to look OK, re-assemble
them and test the mixer. If the motor still won't run, then I might suspect
a defective Phase Control Board (39).

Make sure the Speed Lever and and the Speed Link are in place
and operating smoothly. The two Large black screws you are referring to
are the Motor Brushes Caps. The Carbon Brushes are keyed and
designed to be inserted into the Motor Housing but one way. If you
insert them in wrong, they will not make contact with the Motor Coils
and you mixer will never run.

All you have to do now is adjust the mixer speeds (if necessary):

KitchenAid stand mixer KSM50PWH. Was kneading dough with dough hook attachment and it quit turning. Motor works fine but the part that's supposed to go round and round doesn't. Can I fix this?

The Nylon Worm Gear has stripped. This is designed into the part so if the Mixer gets overloaded, it won't burn out the motor. Which is odd if you have the reset switch like I do.
