Question about KitchenAid K45SS Classic Stand Mixer

1 Answer

The Kitchenaid mixer stops and the motor just whirls without moving the paddle. This happened today when I was making dough. I seemed like the load was too much for it, but I have made this recipe many times without any problems. It sounds to me like a gear is stripped or missing. My machine is 12 years old and has been wonderful.

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

The paddle on my kitchenaid won't turn. It just makes a humming noise. Any suggestions?


Is the humming noise the sound of the motor straining to turn without moving (it won't last very long like that) or the sound of the motor turning but not operating the paddle?

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:

I can hear the motor running, but the attachment does not move.


Sounds like what happened to my wife's mixer. There is one nylon gear in the drive assembly that is designed to break if too much load is put on the mixer. Like what can happen with dough or butter that is too hard/frozen. That is designed to save rest of the mixer. Sounds like you need to replace the KitchenAid Mixer Worm Drive and Pinion Gear Assembly. In our case, it was not the nylon gear that broke, but a small pin that is this gear assembly. By getting the assembly & not just the nylon gear, you cover more of your bases. I found a video on line that walks you through replacing the part. I also bought the part online. The assembly part, including shipping cost me $12.95.

Hope this helps.

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.
