KitchenAid K45SS Classic Stand Mixer - Page 2 Questions & Answers
The top of the mixer began shaking and thumping
Tip the machine upside down on a towel, centralise the hinge pin and tighten the grub screw that locks it into place. This is right up inside the pedestal, there is only one screw there to see.
Now stand it up and fit the mixing bowl & flat paddle, turn the machine on speed one, if the paddle is tinging on the bowl then we now need to set the head height. Turn the motor off.
Raise the motor up and from the front of the machine look in by where the motor hinges on the pedestal. You can see one screw head there. If it's tinging the bowl then you need to turn the screw anti clockwise enough so that the paddle no longer tings on the bowl.
Once it's stopped tinging put it onto max speed and make sure it still clears at high speed, if not turn the screw until it stops tinging. That's it.
The dough hook on my KitchenAid Classic no longer fits on the shaft.
Get a round file and gently rasp it out, you are trying to remove the build up in the hole not rasp the metal away. Flour dust gets in the hole and embeds itself into the soft metal of the dough hook. Also clean the shaft if you can see any dark patches on it. The shaft is good quality steel so you can use fine sandpaper on it without really removing any metal. It's not uncommon for a paddle or a hook to become frozen onto the shaft from flour dust getting in there while mixing. The first time I encountered it I had trouble convincing myself the flour was the problem, I've seen enough of them now to know that's what it is.
Kitchenaid artisan mixer does not turn the blade at low speeds
If it is the worm gear then the planetary will stop turning when there is a load on the paddle but the motor will continue to run at the speed you set it at. I'd be checking the carbon brushes, checking that the field assembly has not loosened up a bit and then I would see if the speed control plate adjustment screws are loose. I'd then reset the speed and see if it stays as it should be.
I have a 275W Classic
There are lots of places to be looking, first thing I would look at would be under the rear cover to make sure the two nuts that hold the rear motor bearing housing in place are nipped up. You don't wring the neck on these nuts, if you over tighten them you will deform the rear bearing housing.
If you can find someone local who has been doing these mixers for a while they will be able to give it a once over. It's unlikely to be expensive. Best people to ask is Kitchen Aid, they should know who does their warranty work in your area. If you are in new Zealand it will be me.
The latch/switch on the speed control board is stuck
You need to take the back cover off and then split the gear cases to find the mechanical reason why the lever is stuck. Take the motor off the pedestal, remove the planetary and undo the 9 screws that hold the bottom gearcase to the top housing. You will need to unplug the white and the black wires from one side of the speed control plate.
My kitchen aid mixer bowl falls out when I'm mixing
Hello Heather,
Either the grooves on the bowl lock plate are worn out, or the grooves on the actual bowl are worn out. I would start with replacing the bowl lock plate. Here is a link to the part:
KitchenAid Mixer Bowl Lock Plate 4163032
This part is really easy to replace, it is held into place with three screws, remove those screws (make sure to hang onto those you will need them to re-install the new part). then you should be able to pop the old plate out. To install the new plate like up the screw holes, and press into place, sometimes you need to lightly tap it into place with a rubber mallet as it is suppose to be a very tight fit.
Once that has been replaced your bowl should lock into place tightly. However there is always a chance that the bowl has been worn down and may need to be replaced. Here is a link to the 4.5 Quart bowl:

I just searched the KA parts data base for this model and there is no such part???
There are a few parts that make up the speed control mechanism, the selector can only be the knob and lever. That moves the speed control plate which is the ********* square thing under the back cap that tilts when the lever is operated. There is a governor on the end of the armature under that control plate, that governs the speed by cutting the power through a circuit to maintain an even speed. Above the black control plate is a PCB (phase board I think they call it) that along with the other bits & pieces regulates the power to the control plate.
I didn't lock the bowl and the slide bar that
Hi CHARAD, The easiest thing to check are your mixer’s brushes. During the disassembly, did your husband remove either or both of the motor’s brushes (from the side of the mixer’s head)? If yes, then he needs to check their alignment on the armature’s commutator. The concave contact face should be resting completely on the comutator. If you've turned it 90 degrees too much, it wont' seat properly and you'll get no 'juice' to the electric motor so it won't start.
If the answer is no, then that would lead me to suspect the problem most likely will be with your speed control assembly, which may have been damaged during the ‘crazy bouncing’.
Since your husband has already disassembled your mixer once I hope he had your mixer’s Parts List manual on hand, but if he didn’t, you can download a PDF version from the KA website: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case use K45SSW, and select the file listed under Parts List (1), K45SSWH0.pdf (341.41 KB). Check to ensure it matches your mixer model.
Turn to pages 6 & 7, titled: Motor And Control Parts, which provides an exploded view for the disassembly and reassembly of your mixer’s electrical components, along with all the parts. You’ll want to focus on Illus. No. 25, Control Plate Assembly.
First inspect around the control plate assembly to ensure all the wire connections are OK. It's possible a connection has come loose during the bouncing. Unfortunately the whole controller assembly is fabricated on a little PC board which was not meant to be 'home fixed', and my 'expertise' ends there. A local small appliance repair shop should be able to determine if the controller assembly is functioning properly or not, or you can just order replacement parts without the testing.
As far as parts go, here are four potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com. Prices for the same part can vary widely between vendors, so do your comparison shopping.
Your husband may already know about the website links below when he worked on the Link & Lever latch, but it’s always good to keep these sites in your ‘toolbox’. 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 and reassemble your mixer.Good luck and have fun. I hope this helps. Howard, Burke, VA

All speeds work but all too fast
the mixing speed was attained by the use of a potentiometer ( variable resistor ) that would have controlled the power into the board or from the board to the motor
it would be under the speed setting knob
maybe the resistor in use is not the right one and is not reducing the voltage sufficiently to do the job
