Question about KitchenAid KSM5PS Heavy Duty Stand Mixer

Motor runs, but beater doesn't turn

My KitchenAid is 15 years old and I am about 300 miles from a repair shop. Is there any way to find a schematic so I can attempt to repair my mixer? The motor runs strong, but it no longer turns any attachment. I am guessing a gear has finally worn out, but I cannot figure out how to open the casing or how to find the challenged piece. Is there a way to get a schematic to see if this is fixable before I buy another?

Re: Motor runs, but beater doesn't turn

Ok, do you want to know how to disassemble? i just inherited a kitchenaid mixer from my brother and it had the exact symptoms. First, using a hammer and pin punch, drive out the pin that holds the beater mechanism. Pull off the mechanism and remove the chrome ring that is above it. You will see about 6 screws under there, remove them. Next remove the 2 screws at the opposite end of the bottom of the motor housing. Now carefully and evenly separate the motor housing. The motor will come off completely. Lay the motor aside being careful not to pull the wires too much. you might want to support it with a box or something to rest it on. Ok now you will see a bunch of grease on the gears. Put the grease in a paper cup as you will need it again. Wipe off the gear assembly and examine the teeth on the gear. chances are there is a spot where there is no teeth at all. Replace that part, put the grease bak on the gears and reassemble in the reverse order. I did mine in no time, just pay attention to what you are doing. The chrome ring is a little tricky to get it back on but it will stay if you keep trying. You might have to roll it against a hard surface to bend it inwards to make it fit tighter. Good luck and let me know if this helped you out!

Re: Motor runs, but beater doesn't turn

The mending shed has the KitchenAid_Service_Manual.pdf available and sells parts. This allowed me to replace the pin that had fallen out of the gear. Mixer was making a clicking sound and then when the motor ran the beater did not turn.

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!

I can't get the beater released from the shaft. I did exactly what the book said, push up as far as it goes and turn to the left, but it doesn't seem to go far enough.

Get a copy of the Repair Part List for your model at
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.

Beater won't turn, but motor is running.

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.

Beaters will not move

You have probably stripped a gear in the gear housing. Here is the breakdown of the gearbox:

The newer "more improved" mixers use plastic gears and they can't take the beating, no pun intended, and fail.

The good news is that the most likely gear to fail is cheap. Here it is on

My kitchenaid ksm150ps standing mixer's top seems to tilt down too low and bounces up and down when mixing

Hi DENISE, by the symptoms you describe it appears that it’s time to adjust your mixer’s Beater to Bowl Clearance adjustment screw, or head locking mechanism (or a component) of it is worn or loosened due to normal wear and tear and needs to be readjusted (or repaired) to keep your mixer head stationery and level.
The instructions for adjusting your beater to bowl clearance are located in your Owners Manual. If you don’t have the original manual you can easily download a PDF version of your Owners Manual from the KA website: (
Click on Customer Care>Locate Manuals& Guides> and enter the 6 character model number, in your case KSM150 and select the file listed for your model that appears under Owners Manuals (66) KSM150PSER1.pdf (732.33 KB) and save that file to your PC. Turn to Page 14 and you will find the instructions for adjusting the mixer head height.
But to save you some time, I have extracted the instructions below:
Beater to Bowl Clearance
Your mixer is adjusted at the factory so that the flat beater just clears the bottom of the bowl. If for any reason, the flat beater hits the bottom of the bowl or is too far away from the bowl, clearance

Tilt-Head models
• Unplug mixer.
• Lift motor head.
• Turn screw (A) SLIGHTLY counter clockwise (left) to raise flat beater or clockwise (right) to lower flat beater.
• Make adjustment with flat beater, so it just clears surface of bowl.
If you over adjust the screw, the bowl lock lever may not lock into place.

If the above doesn’t correct your problem, then you need to look at the Link & Lever Latch assembly. If you don’t have your parts list manual, select the file KSM150PSWH0.pdf (773.44 KB) listed under the Parts List Manual (61).
The manual provides an exploded view for the disassembly and reassembly of your mixer, along with all the part names and numbers. Turn to page5, titled: Base and Pedestal Unit. You’ll want to focus on Illus. #11, Link & Lever Latch assembly, and the related components, which locks the mixer head to the pedestal when you run the mixer. Check to see if something is just loose, exceedingly worn or broken. If something has broken, you can order replacement parts and install yourself.
Here are five potential vendors in no particular order:;;;; and Prices can vary widely between vendors, so do your comparison shopping.
Also, 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 KA mixer yourself.
Finally, 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, repair, and reassemble your mixer.
Finally, if you feel this is beyond your capabilities and will be too difficult to do by yourself you can take your mixer to a local small appliance repair shop and have them troubleshoot and fix your mixer. KA Customer Care can provide you with the name and phone # of the closest authorized KA repair shop in your area or you can do a Online web search, but be sure to get at least three estimates before deciding to commit to one repair shop.
Good luck. I hope this helps. Howard, Burke, VA

Motor runs but Beater shaft does not turn

Hi guys. Kitchenaid does not publish a parts catalog for your KSM90's. Your best bet would be to take it to a small appliance repair place and get a quote to repair it. They may have an old catalog for parts. Try to find a place that has experience with KSM90's. Kitchenaid has left you twisting in the wind, like many,many others. Without these parts drawings, self repair is iffy at best. "For the way it's made"! Indeed. Sorry! I wish I could help more.

KitchenAid 250 Watts; Classic: Leaking Oil

Found this,may be helpful.
Why do I see oil leaking from the beater shaft of my stand mixer?
Some KitchenAid® stand mixers that are not used very often or have been tipped may experience slight oil leakage from the shaft or hub attachment. To avoid the oil leakage, KitchenAid suggests that you run the mixer weekly for short periods of time. Generally, the mixer may lose approximately X cup of oil before repair is necessary. The oil used is FDA approved and is not harmful to consume, should any get into the food that you are preparing.

KitchenAid KSM90 motor runs, but beaters don't turn

I feel your pain. I own a new Kitchenaid, and for some reason they changed some of the metal gears from metal to plastic on the newer models. I suspect it was to make it quieter. But they strip out. Happily, the replacement gears they sell are metal, and once replaced will last a lifetime.

You will either need to replce them yourself, of find a repair shop.
