Please help!

    I'm sure the below answer 2 years late was no help at all but I would be interested to know what you did find was causing the problem. I don't see anything about fitting the planetary that would cause the problem you had with no change to motor sound that you would get if planetary was seized.

I just did this last week!
1 Unplug Mixer 2 Remove screw on TOP of mixer body, at back. 3 Remove rear cover and paper-gasket thing (its not the end of  the world if you end up tearing it a little). 4 the phase control (little circuit board w/wires) is at the top (you  should see it very easily) held on by one screw, remove it. 5 when the circuit board is unscrewed, disconnect all the wires  that are connected FROM THE CIRCUIT BOARD to the  black control plate (NOT all wires-there should be 4 left on  the control plate at this point).  you don't need to  remember where all the colors go as the control plate is  labeled->but looking at them and making sure you  understand the abbreviations would be beneficial  (BK=black, BL=Blue RW=Red&White W=white R=red etc.   6 install new phase control (screw), either buy new thermal  grease (used to keep the board cool->it transfers heat to  the mixer's housing) or try to salvage what you can from  the old one. 7 connect wires, paying attention to labels. 8 reinstall paper gasket, then cover, then screw to hold on back- cover.

Pull the back off and there will be two screws at the top of the Speed Control Plate and a 3rd screw at the bottom. Tighten the top two screws down. bakerboy49203@yahoo.com. Let me know if it works.

I would recommend that you first check the Hall Effect sensor which determines the mixer’s speed.  I had this exact problem and I actually went out and bought another Hall sensor for about $13.  I replaced the original sensor and made sure that the connection between the sensor and control board was nice and snug. My mixer worked as good as new! But I was curious to know if my original sensor was defective, so I put it back in mixer and again made sure all of the connections were snug and tight. Guess what?  My original sensor also made my mixer work!  There was nothing wrong with the original Hall Effect sensor except that the connection between the control board and sensor was not tight--unfortunately I didn't check the connection before I decided to buy another sensor. My guess is that the connection between the control board and the sensor probably loosens or comes undone over time from use and vibrations. To fix your problem:
1.  Download the mixer parts and diagrams from the Kitchenaid website to see what the Hall Effect sensor looks like. BTW the part number is 9703312.

2.  You'll need a phillips head screwdriver to open up the mixer gear case cover.
3.  Make sure that the connection between the control board and sensor is absolutely tight and snug.
4.  Also, make sure that the orientation of the sensor is correct.  It's difficult to tell which way the sensor should be connected because the control board has three prongs and the sensor can attach facing up or down. After you've made the connection, run the mixer. If it still doesn't work, disconnect the sensor, reconnect it with the prongs facing the opposite direction and try it again.  I actually found the right sensor orientation through a little trial and error.  But by going through this trial and error, I also had my Eureka moment when I realized that the original sensor probably would also work if it were reconnected with correct orientation.  
5.  This whole process probably takes about 10-15 minutes to perform.
6.  Finally, use your common sense and make sure to unplug the mixer before checking, connecting or disconnecting anything.

SOURCE: The kitchenaid speed lever is bent and jammed

Hi TIMDEIST, I hate it when you drop your mixer... they’re really not designed for gravity testing. Let’s see what you can do to get it fixed and operable again. The good news is that this can be fixed quite easily (OK, maybe a little effort) by yourself, if you are a DITY type person, feel adventurous, and your mixer is not under warranty. Be 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) (definitely check to see it this 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 6 & 7, titled “Motor And Control Parts”, and locate Ill. Nos. 1, 2, 3, & 4. #3 is your Switch Lever and stud. If you can’t straighten it out then you will need to replace it. It might also be a good idea to check and see if anything else might be out of alignment due to the sudden stop when it was dropped.
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. Here are some links to several excellent websites that detail the disassembling/greasing and reassembly of a KA Mixer.
Finally, here are some links to several excellent websites that detail the disassembling/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 Switch Lever, and reassemble your mixer.
Good luck, I hope this helps. Howard, Burke, VA

Why wont my classic kitchenaid mixer switch off


Good Morning,

There is a spring inside your mixer attached to the speed control switch and speed control arm, the spring can sometimes get caught on the slide bar that is just below it inside the mixer. The other reason is that the speed control switch plate in the rear of the machine (that the spring attaches to) vibrates the three speed adjustment screws out or in and the spring will pull the speed switch (control arm that you use to control mixing speed when using the mixer) back to the stir position after you try to turn the mixer off.

If it is a spring problem you will have to do a full tear down to get at the spring and either free it or replace it. If it is a problem with the adjustment screws on the speed plate, that can be handled at the rear of the machine and is twice as easy to get at but sometimes much more frustrating to adjust. There are "YouTube" videos on the internet that will walk you through the process of adjusting your speed control plate just Google "adjusting speed on kitchenaid mixer" I hope this helps. please let us know if it does and if you have other questions just post them here and we will "FixYa"

Agitator shaft replace


Yes

If you have not gotten this taken care of yet. Turn your mixer upside down and remove the silver drip ring and then take out the drive pin with a punch, the pin holds the planetary on and in place. now with 2 screwdrivers from position 5 o'clock and 7 o'clock gently but firmly pry up until the planetary breaks loose and comes of the center shaft, now you will need some snap ring plyers to remove the agitator shaft, once you look at it you will see how to take apart easy.

Kitchenaid mixer leaking oil


Get a copy of the Repair Part List for your model at Kitchenaid.com
Grease inside the Planetary Assembly (the shaft is tight fit to the Planetary
plate at the factory and is not designed to be taken apart, so do not use
any hard object such as a screwdriver to separate them) over times can
turn to liquid and leak down the bowl. Removing the Planetary assembly
and adding Kitchenaid Food Grade Grease is not a task for a novice.
To properly remove the Planetary Assembly, you must work from inside
the Transmission Housing: Remove in this order: Retaining Clip(25), Bevel Gear(21),
Retaining Pin(18), Worm Follower Gear(19). Use a soft mallet to tap out the Shaft
of the Planetary Assembly(15). Re-assemble it in the reverse order.
Note: The Bevel Gear is extremely tightly fit on the shaft, and a pin punch
must be used to remove from the shaft.

How do I remove the top of mixer to replace speed control lever?


In quick terms, first unplug it then remove the head. Take off the band, this is where the two halves join. Undo any screws holding the halves together. Remove the pin holding the planetary in place. Remove the trim disc. The planetary assembly lifts out but you may need to work around it carefully lifting it a little at a time.

Leaking oil where beaters connect


Hi Maureen. Your K45SS needs to be serviced. The old grease and the oil that has separated from the grease must be removed and the unit cleaned. If you, or someone you know, are up to the task, go to mendingshed.com and download the Kitchenaid Service Manual. This very thorough manual will assist you with the task at hand and with future repairs.

The replacement grease I recommend is Chevron FM ALC EP-2. This is a "Food Grade" grease which is non-toxic should some drip into your mixer bowl at a later date. The planetary gearing should also be removed, cleaned and regreased.

Go to kitchenaid.com, click on Customer Care and click on the Manuals button. In the search window, enter your model number thusly, k45sswh and download the parts drawings for your mixer. These drawings will give you an "exploded view" of your mixer and will come in handy if you need to order parts. Mending Shed also sells replacement parts.

Once your mixer is back in service, run the unit for a couple of minutes every week, this will help keep the oil suspended in the grease and extend the life of the grease.

I am unable to remove housing cover of Kitchenaid Mixer #K45SSWH


Hi. Goto www.kitchenaid.com and do a search for your model#. Look for the manuals tab, locate and download the parts list for your mixer. These drawings will assist you with disassembly and reassembly. Remove the Planetary assembly by driving out the single pin that holds it to the mainshaft. Clean and regrease it too.

Over time the grease in your mixer will begin to separate into oil and harder grease base. It's time to remove as much of the oil and grease as possible, and then regrease.

To extend the life of your grease, run your mixer for a few minutes every week to keep the oil suspended in the grease. If not used for a long time, the oil will seprate.

I recommend using Chevron FM ALC EP-2 food grade grease, and after 5 years or so when it begins to drip, if you get a few drops in your bowl it won't matter much, in comparison with a petroleum grease that you shouldn't eat at any time.

Goto www.mendingshed.com and find their free Kitchenaid Service Manual and download it. This manual covers your mixer.

Regreasing your mixer isn't difficult, it is however, very messy to clean and regrease, so keep plenty of paper towels, rags, etc. handy. Latex or rubber gloves will help.

Kitchen Aid Classic mixer


There are 2 possibilities, the attachments are worn out where they go on the shaft, simply replacing them could fix it, the other is the shaft is worn out inside the planetary ( where it spins), if it moves allot, 1/8 " or more from side to side, the housing is probably worn, and the planetary needs to be replaced, easy job, don't know cost, a new mixer may be in order.

Attachments won't turn


most likely a stripped worm gear if the motor still runs but the attachments/planetary gear won't turn.
Did this happen when mixing a big batch of dough or when something fell in the bowl that shouldn't have?

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.
