Thebsjunk - I don't know if you've canned the old mixer. If you've bought a new KA, congratulations to Kitchenaid. If you haven't, there's still a possiblilty that you might be able to fix it yourself. (For the price of KA mixers you'd think they's last a 'lifetime', but alas, KA quality is sorely lacking from their current products...but I editorialize.)
It's quite possilbe that you've had a gear tooth break in the transmission, which would lock up and prevent the planetary gear (agitator) from rotating in mixing bowl. This is what happend to my wife's 6 Quart Pro KA mixer. Since it was out of warranty, I decided to troubleshoot myself. First I downloaded the Parts List manual from the KA website so I knew what to expect. Then I easily disassemble the mixer to find that a bevel gear tooth had broken. After ordering the correct parts, and reassembling, it works better than when we first upacked it. The loud whining is absent...
If the motors gone bad, you can still replace that, too. Fixing your mixer yourself is much easier than shipping it off to a repair center, and you have the gratification of doing it yourself.
I hope this helps! Howard, Burke, VA

Buy a new mixer unless you are able to replace the motor because it is most likely burnt up because we have gone through 6 mixers and the motor slows down and eventually stops and just buzzes

SOURCE: Grinding Noise

If it's metallic sound you are loosing teeth on a gear or two.  This is caused by lack of lubricant or simply fatigue of the material of the gears.  Don't use it, you can get metal flakes in your food.

Take it in to a repair shop and have it fixed.  The money spent is well worth it because if done correctly will last another 12 years.

this is common for any device that has a motor,either the gears are grinding or the motors contact brushes need replacing, it will have to be looked at to determine the exact cause

SOURCE: Kitchenaid mixer motor makes loud grinding,

lgardash, Are you sure it's the motor or could it be the transmission?
It 'sounds' like you've got some transmission gear issues, and a situation similar to my wife's mixer, which we got new in Dec 2006. (Within a week of her first using it, she contacted KA Customer Care and the only 'care' they offered was an explanation that the new KA Pro Mixer gears are all metal and to expect it to be louder than previous models that used a plastic gear (to fail). Well, there's an acceptable level of noise, and an unacceptable level (you don't need to be a mechanical engineer to know when something doesn't sound right) and it seems that my wife's new mixer's operating noise level was always unacceptable. It finally 'died' this past October.) OK I've vented enough on KA... now what might be your problem(s)?
It could be as simple as thorough normal use the gears have shifted slightly in the transmission and the gear teeth are making different contact, hence the grinding/squeaky noise. The higher the speed, the louder, higher pitched sound you'll get. Alas, the noise may also be indicative of a potential gear failure (after our mixers increasing noisiness, the bevel gear broke and the mixer 'froze').
If your mixer is under warranty, contact Kitchenaid. If it's out of warranty, then take it apart and do a diagnostic exam of the gearing. Whatever you find you should be able to fix yourself. Be sure to have the Kitchenaid Part Manual (Part No. 8212278 Rev D) on hand if you attempt to disassemble yourself. It also lists all the parts so that you can determine, which parts, if any have failed. You'd think that the Kitchenaid name would warranty their mixers for a lifetime... So much for quality in America today!
I hope this helps, and good luck! - Howard, Burke, VA

SOURCE: kitchenaid mixer makes a lot of noise. The beater

Hi - I've been searching for general info on KitchenAid stand mixers and ran across this so I'm throwing my $.02 in... Since KA stand mixer bases are essentially made of cast metal parts, there is a very slim chance that there is a lateral misalignment (side-side) unless it got dropped...eek! Sounds like a head height adjustment issue. Check out this from KitchenAid Conversations:

Good luck.

My Kitchenaid mdl: KSM 155gbca is making a loud bumping noise with or without an attachment.

It is more than likely in the planetary or the fuse gear inside the gear box. Try it once you have the planetary off before you go looking inside the gear box. Easiest is planetary problem but far far more likely is the fuse gear.

It appears that you've got some internal transmission gear issues, and a situation similar to my wife's mixer, which we got new in Dec 2006. It could be as simple as the gears have become loose and are making different contact, hence the noise. The higher the speed, the louder, higher pitched sound you'll get. It may also be indicative of a potential gear failure (after all our increasing noise, the bevel gear broke and the mixer 'froze'). If your mixer is under warranty, contact Kitchenaid. If it's out of warranty, then take it apart and do a diagnostic exam of the gearing. Whatever you find you should be able to fix yourself. Be sure to have the Kitchenaid Part Manual (Part No. 8212278 Rev D) on hand if you attempt to disassemble yourself.

Theres a loud squeaking noise when the mixer turned on

Hi. These mixers normaly make a lot of noise when in operation. Go to the shop that sold it to you, or any place that has these units on display and ask them to turn on the mixer for a demonstration. If their mixer does not make the same noise, then contact Kitchenaid Customer Service and ask for a replacement under warranty. If this solution assists you, please rate it. Good luck! ricardok45
