Hi, BLSMLK1, Sorry to hear about your KA mixer. It should never ‘bite’ the hand that feeds it, but maybe until you get your speed selector switch fixed or replaced, unplug prior to switching any mixing blades, whisker or dough hook. Power machines can break bones, or worse... From the symptoms you describe, it seems to me that the selector lever attachment screw has loosened, and possibly the speed detents have been damaged so they don’t engage the selector lever and the spring will win every time.
The inspection and troubleshooting of the inside of your mixer is a DITY capability, particularly if your mixer is out of warranty. Just be sure to have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website at: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case, KSM90P, and select one of the files listed under Parts List (check to see it this matches your mixer model). Turn to pages 6 & 7, titled “Motor And Control Parts”, which provides an exploded view for the disassembly and reassembly of your mixer’s electrical components, along with all the parts. Locate Illus Nos. 1, 2, 3, 4, which are Pivot screw, Spring washer, Switch lever and stud, and Control plate spring respectively. Disassemble your mixer to the point of accessing your speed selector assembly, and inspect the pivot screw to see if it hasn’t worked itself loose over time. That’s the simplest thing to fix. If loose, tighten. Inspect the rest of the assembly to determine if something else hasn’t broken or gotten out of alignment. If something has broken, you can order replacement parts and install them yourself.
As far as parts go, here are four potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com. Prices for the same part can vary widely between vendors, so do your comparison shopping.
While your mixer is apart it would be ideal to check for any other unseemly wear and tear on the gears, etc. It can be messy but quite gratifying to diagnose and repair your mixer yourself.
Here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer.
Between these three websites and their excellent pictures and descriptions and your Parts List manual, you should now be able to completely disassemble and reassemble your mixer.
Good luck and have fun. I hope this helps. Howard, Burke, VA

Hi, This is not normally a difficult question. Normally the answer would be - Yes no problem. I have taken every kind of appliance overseas. But this particular model has an electronic speed control and finding out the exact details of the electronic clocking is a problem. My best guess is that it will work just fine but at a slightly slower speed like any other 60Hz appliance. Oh and by the way you're gonna need a pretty big transformer this thing pulls 325 watts so you should go to at least a 400 watt transformer for doughs and heavy batter. The thing you could do to find other folks experience is to go to the kitchenaid forum or military wifes forum online and ask if anybody has taken one of these overseas. Good Luck!

Constant pushing of the beater onto the Agitator shaft (40) can cause
it to be pushed in too far into the Planetary (33). With the beater in place,
use a rubber mallet to slightly tap the edges of the beater and push the
shaft out until you can see the retaining clip.
Now you have enough clearance on the shaft to push the beater upward
and twist it to remove it.

You need to adjust the mixer speeds:

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. Make sure that the Control
Plate is not damaged in any way, contacts are not charred or burnt,etc...

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
Speed 10 - 280

I had your same issue with the speeds. I think you need to adjust the speed through the speed control panel.
Open the back spherical cover on the Kitchenaid KSM90, the area with one screw on the top. You should see the speed control panel, a black and gold square connected to wires. There should be three large silver screws - two on the top, left and right - and one on the bottom. If you turn the top two screws clock wise the machine slows down at lower speeds. When you adjust the bottom screw, the higher speeds are effected. This process is called "tuning" and you can find an online video how-to through sites like Youtube.
As for the squeaking, you maybe replace some of the grease inside of the machine. Food grade gear lube would do if you are up for the challenge, but kitchenaid also sells a grease for their stand mixers for a pricey $20. It isn't hard to put in new grease and clean out the old but requires a lot of disassembly.

Make sure your Beater can slip in and out of the Beater Shaft
easily. Do not force the beater onto the Shaft if the shaft is bent.
If it cannot be removed easily by hand, use a soft rubber mallet
(not a steel hammer) to slightly tap the beater so it can be moved
up and down the shaft or from side to side. Then you can easily
turn the beater left and remove it from the shaft.

From Kitchenaid Manual:
To Attach Flat Beater, Wire Whip, or Dough Hook
1. Turn speed control to OFF.
2. Unplug stand mixer or disconnect power.
3. Tilt motor head back.
4. Slip beater onto beater shaft and press upward
as far as possible.
5. Turn beater to right, hooking beater over pin on shaft.
6. Plug into a grounded 3 prong outlet.

To Remove Flat Beater, Wire Whip or Dough Hook

The KSM90 is very similar to the 5-qt. tilt-head Artisan Stand Mixer.

Two things you can do for a 24-year old machine:

1. Replace both motor brushes (Black large plastic Caps on each side
of the Moto Housing). Without these, the motor wouldn't even run.
2. Replace the Worm Gear (the cause of the Rough Loud noises)

Download a copy of the Repair Part List from Kitchenaid.com for
your model KSM90.

Also don't forget to tighten all the screws inside the mixers and use
fresh Kitchenaid Grade Food Grease for all the gears.

KitchenAid KSM90... | Answered on Jul 04, 2011 | 347 views


It sounds like the Worm Gear is going out. The faster the motor runs,
the more damages the Center Gear is grinding away the teeth of the
Worm Gear. Things start to slow down, and eventually they will come
to a halt. It's time to replace the Worm Gear. Also make sure to use
new fresh Kitchenaid Food Grade Grease with the new replacement.

go to a technician and have the motor rewinded again. because your machine encountered a short circuit so the motor needs to have a new rewind. Hope the other parts are not affected.

KitchenAid KSM90... | Answered on Jun 18, 2011 | 373 views


Hi, Did you push the beater in so that it clicks. If all is good there, gear box maybe at fault or jammed. Take it to a service center for repair. If you are machanicly inclined (DIY) Take it apart and see why its not turning. Good luck.

KitchenAid KSM90... | Answered on Jun 04, 2011 | 237 views


Hi dickgadsby,

Please try to move the lever slightly up or down while moving it forward to see if this will free the lever. If not and still lever can't be moved this means that you need to remove the top end assembly to check and replace parts. If you don't have the parts list manual you can download it from Kitchenaid's webiste. Pages 6 & 7 provides an exploded view for the disassembly and reassembly of your mixer. Check Illus Nos. 1, 2, 3, 4, which are Pivot screw, Spring washer, Switch lever and stud, and Control plate spring. Once you have disassembled your machine inspect the pivot screw to see if it's loose. If loose, tighten. Inspect the rest of the assembly to determine if something else hasn't broken or gotten out of alignment. If something has broken, you can order replacement parts and install them yourself. You may order parts from repairclinic.com or searspartsdirect.com. Go to this link for it provides instructions on how to disassemble your machine.

Hope it helps.

Thank yu for using FixYa.

If you can still find them in stores they average $225.00. Used ones go for $135 - 200.00 depending on what accessories they have. The full accessory kit can still be purchased today for $129.00 at Home Depot.

if the head wobbles on stand, flip mixer upside down, and tighten the pivot pin screw way deep down inside stand. you will need a long flat blade screwdriver. it's probably loose.

run under hot water over where the dough hook attatches to shaft. this should free it.

your control plate is worn out. it will need replacement.

be sure motor brushes are inserted in the holders correctly; as 1 side of carbon brush has a shaved corner; and must be inserted as such. you will need a flashlight to shine into holder to see the shape of holder. i've seen this many times.
