SOURCE: grinding sounds and slower mixer speeds

It sounds like you may have a broken worm gear inside your mixer which is a common problem.It is a wearable part which transfers the power from the motor to the main drive. It may be chipped or damaged right now, and running it will cause more damage. Part number for the worm gear is W10112253. This does however require some know how to replace. Hope this helps

Thanks

My kitchenaid artisan mixer doesnt run fast enough


It may be seizing up the bush that your accessory drive runs in, if you can see grindings in the front by the square drive that is a sign. Here in NZ that bush is only available as part of that whole top cover/housing. The accessory drive gear will also need to be replaced.

KitchenAid mixer making grinding sounds.


Is your KitchenAid mixer making loud grinding sounds and running slow? This is a common problem with these mixers. One or more of the screws holding the beater drive mounting plate in, has backed out, and is rubbing against the plate making a loud grinding sound and slowing the unit down.

The solution involves removing the beater driver shaft and plate and taking out all the mounting screws, then reinserting them with lock tite, available at Lowes or Home Depot in the hardware department.

The beater shaft, located vertically, has a pin in it which needs to be driven out with a punch and hammer. Then a "C" clip must be removed from the base of the shaft. You will need some "C" clip pliers available at any automotive parts store. Using the pliers insert them in the holes in the "C" clip ends and squeeze the handle. This will spread the "C" clip and allow you to slide it off the shaft.

Next pry the chrome bezel off around the exterior of the shaft which will expose about 6 screws which need to be taken out. These are the screws causing the problem. They should be removed one at a time and replaced with lock tite added to the threads.

Reassemble the mixer after all the screws have had lock tite added. This should quiet your unit and make it run faster.

Thanks for using FixYa and for the great rating.

On low it makes a really loud grinding noise the higher you turn up the speed the slower it becomes.


It sounds like the Worm Gear is going out. The faster the motor runs,
the more damages the Center Gear is grinding away the teeth of the
Worm Gear. Things start to slow down, and eventually they will come
to a halt. It's time to replace the Worm Gear. Also make sure to use
new fresh Kitchenaid Food Grade Grease with the new replacement.

Mixer makes a loud ticking or clicking sound at low to moderate speeds, like a clock tick. At faster speeds and high speed, the loud tick is drowned out by a louder grinding sound. All of this sounds...


I don't have a direct answer for you. There are many things which could cause the noise from a beater simply hitting the bowl to internal gear problems. You did not say which model you have so take a look at the two Service Manuals linked below. One of these ought to cover your machine.

The attachment/accessory "screw" fell into my mixer while the beaters were mixing a cake batter. The mixer froze up when it hit the "Screw" and now the unit won't turn on. Did I burn up the motor? Does...


Sounds like a classic case of the gears jumping out of sync. This is an issue that needs to be handled by a repair place or sent back to KitchenAide. The motor on a KitchenAide is very strong and it sounds like when the cap for the accessory fell in it must have somehow gotten jammed, although I really don't see how that would be possible unless there was something else in the mix as well.

My Kitchen Aid KSM150PS Artisan red mixer trembles alot and makes a grinding sound when I use it. I've exchanged it once already and have the same problem again.


Kitchenaid mixer are supposed to make a slight grinding sound while operating under load. This is simply the gears meshing together while the motor is turning them, but if the sounds gets worse or is already a metal grind type sound this could indicate a broken worm gear inside the unit, and shouldn't be run any longer. However if your mixer isnt on SOLID ground this could cause the tremble as well.Hope this helps

Kitchenaid mixer motor makes loud grinding, squeaking noise.


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
