If it is leaking you are going to have to go inside the gearbox to change the grease so whatever is wrong inside may become obvious when you take it apart. Remove accessory cap from the front and look for any dryish grindings inside there.

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.

SOURCE: Question regarding KitchAid mixer, Model K45ss.

Yes this indeed does sound like you have a problem. There could be a couple different cause of this noise. If your main drive or worm gear has been damaged, it is likely to not run at all or jam up. So i think this is not the problem. There is however a codder pin located inside the transmission gears this can be seen by removing the upper housing of the unit, and then exposing the oil and gears. clear away the oil surrounding the gears, and save this grease for later. After this you should be able to visually see this codder pin AND the gears, rotate the gears while inspecting them and the pin. If the pin is slightly bent or broken this will make the grinding noise that your are talking about, while still operating and driving the unit. part number for the codder pin is 9705444. If however the noise is coming from the motor area this could indicate a worn or faulty motor bearing. This can cause the motor to operate on an angle and can cause a rubbing noise from the cooling fan or the winding of the motor itself rubbing on the mixer housing. Part number for the braket and bearing is 3180526. both are relatively cheap and easy to replace. If you find and fix the problem be sure to inspect or change the oil as this can often have metal chunks and other particles. Hope this Helps

Thanks

SOURCE: My Kitchenaid mixer (k5ss lift bowl?) smells hot

I think you have a K45SS. It sounds like there is a problem with one of the gears, probably the worm gear. The worm gear is designed to be the first to fail if the mixer has struggled with a heavy dough or other difficult to mix substance. The best way to establish the cause will be to open the head up and check the gears for signs of damage.

SOURCE: Have a KS55 mixer that

A lot of things can happen to a piece of machinery after 4 years of idling time.
Dust, moisture, rust and dry hard Grease are just few of the problems. The
good news is it's not hard to put it back into service again. Obtain a copy
of the Repair Part List from Kitchenaid.com and start opening up the mixer.
Vacuum all dust inside, remove dirt and debris. Open up the Transmission
Housing and scoop out of the old grease. Use fresh Kitchenaid Food Grade
Grease for all gears including the Agitator (part of the Planetary Assembly) and
you are good to go.

Hobart Legacy HL200 stopped working?

That is a $10k to $20k mixer, depending on where you buy it. I have used one of these. Unfortunately, grinding noises that result in the motor stopping can be fixed with a power disconnect.

Grinding noises = dry bearings, to seized bearings, to shredded or stripped gears. You need a Hobart Service Tech.

Speed problems with kitchenaid artisan mixer.

It sounds like two issues, the first is going to be the phase board, you will need to replace it, that should fix your speed issue.

The second issue will be a stripped gear, in that mixer there is a nylon gear that commonly goes bad, that would be the worm gear.

Here is a link to the phase board: http://www.mendingshed.com/kaphaseboard.html
Here is a link to the worm gear:
http://www.mendingshed.com/kawormgear.html

Also here is a link to the service manual: http://ep.yimg.com/ty/cdn/mendingshed/kitchenaidservicemanual.pdf

The service manual will show you how to take apart the mixer, and put it back together.

My governor assembly is broken and the speed controller does not work

You will need to buy a new governor from Kitchen Aid and possibly the speed control plate at the back. Often when the governor explodes it damages the contacts, they aren't expensive and it's easier than fluffing around trying to straighten it up.

Low speed noise

Check that the nuts under the back cover at the sides have a bit of nip on them. It could be the armature polling on the fields. DO NOT OVER TIGHTEN THOSE NUTS.

Kitchenaid rrk5a not operating in lower speed settings

The RR of your model number stands for reconditioned, your actual model number is K5A, I believe that the side trim band says Hobart on the side, if not you may have a new trim band (Generic type) put on during the reconditioning to pretty it up. In any event in the back of the mixer is an end cover, at the top is a small Phillips head screw, remove it and lift the end cover up and slightly out, (because there are two small and fragile clips on the back that can be easily broken off, they help hold the end cover in place so up and out ) once the cover is removed you will see a black and copper plate with three chrome screws on it in an upside down triangle shape, the two top screws are for adjusting speeds from stir to 6, the lower one is for adjusting speeds from 6 to 10, Turn the screw on the top left to the left a quarter turn while the mixer is in the stir position. it should start turning. if not turn the screw on the right a quarter turn, the mixer should start, if not turn back the other way (both top screws a half turn) if it machine does not start then there is a strong possibility that it is the bottom screw, the bottom screw can and sometimes does get turned in or out due to the pressure caused by contact that it makes with the speed control switch bar attached to the side speed control switch, so let's try that one, turn it counterclockwise or clockwise (no more than one full turn) a quarter turn at a time, if it is the bottom center screw causing the problem then it should start within a full turn, try not to turn the screw in either direction more than one full turn as you can really screw up your speed settings. Don't panic I am probably making it sound more difficult than it really is, just remember that a little is a lot. I am a KA tech and every machine that I have worked on that has a low speed not working correctly it has turned out to be these 3 screws.


If your machine goes to high speed from the get go no matter where you put the speed switch, well that is another problem, but if your machine is not working on lower speeds when set to the lower speed and it does work at higher speeds when the switch is set to the higher speeds then it is the 3 adjusting screws on the speed control plate. hope this helps if not let us know

KA 600 is making a clinking noise when mixing.

Tll,
It sounds like it could be an issue with the gear, the motor housing could have a crack in it. The problem could be much more involved as well. Put the unit on the slowest speed and see if you can stop the mixer from spinning. If it hiccups or stutters, that means you have a stripped gear. If you cannot stop the unit using your hand ON THE SLOWEST speed then there could be a problem with the motor housing or the motor itself not being held in place properly.

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.

Kitchenaid 250 watts k4ss mixer

The repair manual says that the mixer can make this grinding sound at slow speed, like stir or 2. This is normal, especially until it warms up. This is the sound of the gears turning at slow speed.
