KitchenAid Mixer struggling to spin?

I have a 4 year old professional series kitchenaid mixer. I was making bread and it stopped working. Opened it up to see if the worm gear was stripped and it was. I replaced the worm gear with the correct part and put it back together. Now I can hear the motor going when I turn it on, but it has a hard time rotating and will stop randomly and won't spin at all if I put any resistance on it. Help?

Check everything you have done for a mistake, the pin through the planetary, the pin through the fuse gear and the pin in the main shaft that drives the bevel gear. That's the gear that pinion gear on the fuse gear shaft mates with. After that you are left with a fuse gear fault. I am assuming that the motor is turning at normal speeds and not somehow binding up, no reason why it should as motor stays in one piece during gear changing procedure.

Testimonial: "Could you explain in more simple terms? I'm not very handy so I don't know what most of the parts are called. I tried taking it apart again and putting it back together. Now it spins but stops when I put anything in the bowl or barely touch the beater."

    Apart from a faulty new fuse gear (very unlikely) I can only think that one of the 3 driving pins in the machine is missing or broken. You can check the planetary pin from the outside of the machine. It's where the beater attaches and goes sideways through that shaft down the middle of the planetary hub. The planetary hub is the part that carries the beater around in that wide circle. There is another pin that goes through the new fuse gear you have fitted and locks it onto the shaft that goes through the middle of it. I have just had another thought, I wonder if maybe you have fitted the new fuse gear upside down, they are offset, maybe it does not engage with the motor armature when fitted upside down, maybe you should look at that first. I don't even know if it is possible to put the pin through it if you do put the gear on upside down, I never have so don't really know.

hi

there is a ring clamp on top of the main worm follower gear on the drive shaft. you might not see it due to the grease.

you need to get one of those weird little pliers with points on them to spread the ring clamp to remove it. Then the gear is just friction fit on the shaft...it's pretty tight. I carefully used a screwdriver to slowly separate the main follower gear from the lower gear and it goes up the shaft....

after a bit you can wiggle the follower gear by hand and it will come up. Then you can see there is a pin holding the drive gear underneath it in place. The pin in my mixer was actually bent (must have been some tough dough).

then you reverse the process to put the gear back on -- except that the top follower gear has to go on the pin in the right orientation or the ring clamp won't fit.

buy your parts from mendingshed.com

hope it helps.

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: The Kitchenaid mixer stops and the motor just

Hi VILLAGEFS, I’m sorry to hear about your 12 year old KA mixer not working. From the symptoms described, your mixer has experienced a catastrophic transmission failure; “like a gear is stripped…” Your particular KA model has a plastic gear designed to fail instead of the whole mixer ‘going up in smoke’. With this ‘fail-safe’ gear stripped your electric motor continues to ‘whirl’, but the power is not being transferred to the planetary and agitator shaft.
The good news is that this can be fixed quite easily (OK, maybe with a little effort) by yourself, if you are a DITY type person, feel adventurous, and your mixer is not under warranty (which it is not). Make sure you 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> then enter the visitor type “Consumer and enter the 6 character model number, in this case K45SSW, and then select the file under Parts List (1) K45SSWH0.pdf (341.41 KB) ( Still check to see it matches your mixer).
Although not providing step by step instructions, the Parts List manual provides an exploded view of the various component assemblies allowing you to see how the mixer all fits together. It is helpful for the disassembly, troubleshooting, and reassembly of your mixer.
Turn to pages 4 & 5, titled “Case, Gearing and Planetary Unit”, and locate Illus. No. 38, Worm Gear Bracket & Gear, including Illus. No. 8, Worm Gear. After clearing all the grease away, you will probably find the worm gear stripped. You can order a replacement part and install it yourself. Do not use the old grease as it will be contaminated with debris from the stripped gear and ‘gum up the works’ if you try to reuse it.
While you’ve got your mixer this far apart you can check for any other unseemly wear and tear on the on the other gears and components. Besides a replacement worm 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).
As far as parts go, here are five potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com; and Grainger.com (for grease). Prices can vary widely between vendors, so do some comparison shopping.
Finally, here are some links to several excellent websites that detail the disassembling/greasing and 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, fix/replace your stripped worm gear, and reassemble your mixer.
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. Good luck, I hope this helps. Howard, Burke, VA

Why can't my kitchen aid mixer turn n


Sounds like the worm gear was stripped. This gear is designed to fail when the load on the motor is too great. This protects the motor from overheating and burning out. By the way, the mixer should not be used above the number 2 speed when using the dough hook.

The worm gear is not all that hard to replace although you will have to contend with a lot of grease. See the Service Manual:

Motor clicks every turn


The clicking is probably a small nick in one of the gears, even the smallest chip can cause alot of noise or make the mixer click. Is the beater shaft still turning when you have a load in the mixer (bowl is full)
Or is it just clicking?

If the beater stops turning it is going to be caused by stripped gears, however if it is just clicking this would indicate just a nick in the gear. Either way I would recommend opening the mixer and replacing the damaged gear/gears.

Your mixer is considered a 5 Quart Professional, which means it has the same parts as a KitchenAid 6 quart mixer. The first thing you will want to do is take the mixer apart and disassemble the gearing. You will want to clean off the gears with paper towels and wd-40. Carefully inspect each gear once clean and replace damaged gears.

In the professional mixers when a gear strips you need to replace the grease and housing gasket, this is because the gears are all metal and there may be metal shavings in the grease which could cause the gears to strip again.

The most common gear to go bad in the Professional series mixers is the Worm Follower Gear (9706529). Here is a link to that gear on our website: http://www.mendingshed.com/wormfollower.html

Also, here is a link to the service manual for the mixer, this will aid you in taking the mixer apart and putting it back together correctly. http://lib.store.yahoo.net/lib/mendingshed/kitchenaid6qtservicemanual.pdf

KitchenAid stops working when anything other than liquid is in the bowl..


There is a non metal gear inside the motor head that is stripped and no longer engaging the worm drive. What happens when you try to assist the turning process (try it only on stir speed, sloooowwwww) if it starts to turn and then stops again then it is the gear I spoke of. It will require tearing down the machine, cleaning all old grease, to insure that you have no ground up parts in the grease, then replace the grease gasket and gear. Hope this helps

The motor is making a grinding noise. The mixer still works, it just sounds weird.


I have fixed many mixers with the same problem. The only part that consistently wears out
is the Worm Gear Follower located inside the Transmission housing. The teeth are wearing out
and becoming chipped. The grinding noises you hear are made by the Worm Gear and the
Follower. As time goes on, the metal filings from the damaged follower will eventually destroy the Follower and the Planetary will stop rotating.
Sooner or later that gear need to be replaced. Also remember to use new Grease after
a new gear replacement (metal filings from the old gear will damage your new gear)

While kneading bread my mixer suddenly starting hanging up at the back side. It makes the full circle but when it gets to the back it stops and "hums" and then sometimes will go on but most of the time...


It sounds like you have lost some teeth from your worm gear. This usually happens when the mixer has been overloaded. The teeth on the worm gear are designed to fail first to prevent more serious damage. To replace the part you will need to open the head on your mixer. The gears are at the front of the mixer packed in grease. It should be obvious that the worm gear has broken once the head is open. If it is not the worm gear, with the head open it should be easy to spot the problem. The gears are available as spare parts from several places on the internet. search for "kitchenaid worm gear"

Hi. Stop using your mixer. If your mixer is still covered by warranty, call Kitchenaid Customer Service, they are very good with warranty repairs.

If your mixer is out of warranty, remove the silver band that surrounds the top of mixer. Remove the top cover. At the front of the mixer, locate the transmission housing which is now exposed. Examine this housing carefully for cracks. If you find cracks anywhere in this housing, you have found the under-engineered plastic transmission housing. Kitchenaid's replacement housing is made of metal. Your plastic housing has no business being in a mixer that is marketed as being able to mix bread dough. It cannot!

If you're confident that you can make the repairs yourself, go to the Kitchenaid website and download the parts drawings. Remove the Trans. housing, remove the worm gear shaft assembly which is driven by the motor.. Remove and save as much grease as necessary to thoroughly inspect the worm gear. Inspect the worm shaft bearings. Look for cracks, or missing pieces on the bearings. Look for crunched cogs on all gears. Be prepared to wait at least a month for your parts to arrive after you order them. The replacement grease should be Shell Darina 2, or Chevron FM ALC EP 2.

If you're not confident about repairing this yourself, call Kitchenaid and determine the nearest "approved" repair shop.

You may be able to pressure Kitchenaid to pay for the damaged parts in your mixer. They are still installing these plastic Trans. housing on new mixers. Insist on a metal cover when replacing. Apparently, Kitchenaid feels no shame in their manufacturing process, and will not issue a recall notice for these housings. They are substandard at best.
