    MY KA. Mixer is KSM90 and the model# is not listed in the PDF manual but, I think they all are constructed the same. It should take me 2-3 hours taking it a part. Great Weekend project. Thank you for the help and assistance.

Hi, i’m sorry to hear about your mixer not working. Unfortunately from the symptoms you describe, your mixer has experienced a transmission failure. You don’t mention how old your KA mixer is or how hard it’s been used, but for your particular model, KA has a plastic gear designed to fail, instead of the whole mixer ‘going up in smoke’. And what it sounds like is that this fail-safe gear finally ‘failed’ (stripped) so that the power from your electric motor is not getting to your planetary (“elliptical rotating part”) and the agitator shaft. What can you do?
The good news is that this can be fixed quite easily (OK, maybe a little effort) by yourself, if you are a DITY type person, feel adventurous, and your mixer is not under warranty you can troubleshoot it yourself. Be sure you have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case use KSM50P (Your K5SS mixer falls within this maual), and select the first file KSM50P.pdf (438.31 KB) listed under Parts List (4) and then check to verify this matches your mixer model.
Turn to pages 4 & 5, titled: Case, Gearing And Planetary Unit for the disassembly and reassembly of your mixer, along with all the parts. Locate Illus. No. 58, Worm Gear Bracket & Gear, including Illus. No. 12, Worm Gear (23 teeth). I suspect this is the weak link in your mixers transmission and causing the problems. After clearing all the grease away, you’lll probably find that is has been stripped.
You can order a replacement geara and install it yourself. While you’ve got your mixer this far apart you can check for any other unseemly wear and tear on the on the gears and other components. Besides a replacement gear, and grease you might consider replacing the gasket, too. You should use a food-grade grease that you can order online (although I’ve seen automotive bearing grease used too – your call). Do not try to reuse any original grease as this should be filled with debris from the stripped gear.
Here are five potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com; and Grainger.com. You should search for ‘food grade grease’. Prices can vary widely between vendors, so do your comparison shopping.
It can be messy but quite gratifying to diagnose and repair your mixer yourself.
Finally, here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer. The mixers displayed in the links are different KA models, but the principles are the same.

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, should you decide to go that route.
If you feel this repair is beyond your capability, then I would seek out a local small appliance repair shop in your area. KA Customer Care can give you names of local KA authorized repair shops in your area, but you can also do an online search to supplement what KA may provide you. Call to explain your circumstances and find out their hourly rate and get an estimate of what they think it would cost to repair your mixer. Also, always obtain three or more estimates – do some comparison shopping.

Take care

Hello,

This could just be that there are dirt underneath or perhaps needs servicing, follow the procedure to service your kitchen aid mixer.

remove any attachments and bowls, and unplug the unit. Carefully remove the drip cup--the silver band over where the attachments are connected--with a screwdriver. Take out the groove pin, which is the tiny pin near the post where attachments are connected, that holds the planetary gear to the center shaft with a small screwdriver or nail. Wedge out the planetary gear with a flat screwdriver or two. Unscrew the small screw on the top of the mixer to release the back cover. Then remove the two screws holding the silver trim band in place and take off the band.

Separate the pedestal and bottom cover, if desired. Loosen the screw set located within the neck (turn the unit over) and then drive the hinge pin out. The pedestal will now separate from the bottom. Take out the screws around planetary gear, which are the screws holding the housing in one piece. Tap to separate the housing. The gears are now in view. Note that the internal workings of the mixer are connected to the cover.

Referring to the manual, remove the control unit and armature. Inspect, clean and replace any worn, rusted or damaged items such as brush housings and holders, fan blades, bearings, brackets and springs. Test the coils for proper resistance. Test (or have tested) the armature with a growler for proper operation. Make sure enough thermal compound is applied if the phase control unit is removed or replaced. Do not try to take apart the governor. After the testing and inspection of internal motor components, reassemble the control unit and armature, being cautious to not over-tighten any screw or pins.

Carefully disassemble the planetary gear unit. Refer to the repair manual for detailed instructions. Inspect the workings to see if any waste or excessive lubricant has built up in the gears. Change any gears, shaft, bearings links and washers that show damage or appear to be worn. Dark gray and/or depression surfaces may indicate a need for replacement. Reinstall all gear components and grease as required with an approved lubrication product. Reassemble the unit.

Inspect the pedestal, cord and exterior for any damage, including the rubber feet and bowl cap. Replace the hinge pin in the neck of the unit with a mallet and tighten the screw set to secure. Using a speed tool, referred to as a strobograph, check the operating speed of the unit. Adjust the speed, if necessary, according to your unit's specifications. Inspect and repair any worn parts in the bowl lift unit if your mixer is so equipped. Test repaired unit for proper operation.

With this, the problem with your kitchen aid mixer should be solve.

Take care.

SOURCE: kitchen aid mixer

the unit sounds like the drive unit is stripped. if the planitary unit is spinning that gear is ok but the one below that is stripped. which is the one that spins the beater. Usually the professional lines are covered under a 2 year warranty. where as the others are a 1 year. I would contact kitchenaid first and see if your product is covered for replacement. they are really good about replacing faulty units. if not the unit can be repaired. It is a simple process and you can buy the parts off kitchenaid. usually the parts come with instructions as to how to replace them but if not repost to me and ill get you the directions on how to replace it.

SOURCE: Kitchenaid mixer makes a clanging noise

Hi. If your mixer is under warranty, call Kitchenaid. They are very good at replacing mixers under warranty.

If you are out of warranty, this is where the fun begins, NOT!

Remove the silver band from around the top of mixer. Remove 4 screws that secure the top cover, remove cover and at the front top of the machine locate the transmission cover. Inspect this cover carefully for cracks. If you find cracks in it...You have just discovered Kitchenaid's dirty little secret. A cheap plastic transmission housing! The failure of this cheap part is the cause of all of the rest of the damage inside the mixer, which may include a destroyed worm gear and shaft, destroyed bearings and their seats. You're not alone. I estimate that thousands of these plastic parts have failed causing great damage to the rest of the mixer

Kitchenaid's replacement housing is made out of metal. If you feel up to the task of repairing the mixer yourself goto the Kitchenaid website and do a search for the parts catalog for your mixer model, these will assist you with disassembly, reassembly and parts ordering.

If you're not up to the task, take it to an authorized repair place once you have put the cover back on.
Even if you're out of warranty, you may be able to have Kitchenaid pay for the replacement parts, they did for my mixer. Be persistent with them and try to get to a manager with your complaint. This cheap piece of plastic has no business being installed on a high-priced machine.

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: Kitchenaid mixer ksm160 stop working after a flash

We have a 10 month old KSM150 and the same thing happened. I called to have it fixed under warranty and their 'Hassle Free' replacement warranty is anything but! The spped controll leaver slides the electrical switch back and forth at the very back of the unit. Looks like there are 2 small metal spring connections that maintain contact when things are working properly. There is one screw at the top of the small dome at the back; removing this screw gives you access to this. I bet you will find that these 'spring connections' have come loose from the vibrations and are causing a short with the exposed electrical terminals. As far as I am concerned that is a design flaw and poses a serious danger of eletric shock or fire and KitchenAid shoud fess up before someone with the wrong breaker in their home gets hurt. I am mad as hell. findsh@hotmail.com

Kitchenaid food processor, motor rotates but when blade is inserted it won't rotate


It will be something in the mechanism that activates that switch in the base. It is more common for the fault to be in the lid but it is not so uncommon for it to be the bowl. You are using the pusher aren't you? That's the mechanism activator. This information is relevant to the wide mouth model.

The mixer won't work the pasta attachment, keeps rotating the mixer motor.


It sounds like it could be a possible stripped gear. You could have a bad attachment drive gear or bevel pinon gear.
Best thing to do would be to take the mixer apart, and inspect those gears. Here is a link to the service manual which will aid you in taking apart your 4.5 quart mixer: http://lib.store.yahoo.net/lib/mendingshed/kitchenaidservicemanual.pdf
Here is a link to the attachment drive gear: http://www.mendingshed.com/attachmentgear.html
Here is a link to the bevel pinion center gear: http://www.mendingshed.com/pinionwormgear.html
Let me know if you have any questions.

Mixer does not rotate hook


Here is the exploded parts list fr a K45, perhaps it will help you replace the stripped gear inside the gear housing. It is probably the gear which is driven by the motor shaft.:

4162897 Worm Gear

It costs around $10 and can be found on the internet at places like:

KitchenAid KSM50P mixer sporadically stops working


Hi, This sounds like you have an issue with the planetary gear system. The mixer has a plastic worm gear inside the planetary that is prone to wear and failure. I would bet that it needs replaceing.

Leaking fluid, oil I think around the kitchen aid ring


Bucksmom, Sorry to hear you mixer is 'leaking'... I hate it when that happens. You don't mention how old or what model your KA mixer is? I assume you mean the band around your mixer with the Kitchenaid logo, when you say 'kitchen aid ring.
Your mixer does have an internal gear mechanism (transmission if you will) which converts the electric motors rotation into the mixer rotation and those gears are located within the mixer. The gears were lubricated at the factory, but depending on the age of your mixer and how it is used, it is possible that the grease has leaked beyond the gasket and that is what you are seeing now.
It is possible to disassemble the mixer to determine where the grease is coming from and troubleshoot if anything else might be wrong within the transmission.
Hopefully the leakage is not getting into your food being mixed. Kitchenaid Grease should be 'food grade' grease, but you still don't want to ingest it.
I hope this helps... Howard, Burke, VA
