    My wife's KitchenAid 300 Watts KSM90 Ultra Power mixer stopped working and I started messing with brushes to see if they were worn. After tinkering a little more it started working. Unfortunately, I started adjusting the spring loaded screws in the back and now the mixer does not go from stir to 10. Does anyone know the factory settings for the screws on the rear motor?

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.

SOURCE: I need speed control senser. Where do I get one?

Hi, RDBOST, it appears as if you’ve identified the problem you’re having with your mixer. And the speed control sensor (Hall Effect sensor) can be ordered from several online KA repair parts vendors. I assume you’ve got a Parts List manual on hand, but if you're lacking one, 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 KP2671, and then select one of the files that appear under Parts List file. Turn to page 4, Case, Gearing and Planetary Assembly and locate Illus. #9, Hall Effect Sensor, part# 9703312. This is what you want to order.
Here are four potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com, that should carry the KA parts. Prices can vary widely (between $4.00 ~ $9.00 plus S&H & tax) between vendors, so do your comparison shopping.
Good luck and have fun. I hope this helps. Howard, Burke, VA

Hi normangremms,

If your mixer does not run slow, it is often caused by the small circuit board in the unit that controls the speed. The easiest way to correct this issue is to check if it is malfunctioning. Here are additional step that you may use to solve the problem.

1. Turn off the unit.

2. With the back plate off, try to adjust the large black plate on the back of the speed control and see if you can regulate the speed better.

3. The plate has 2 screws on the top and one or two on the bottom, depending on the model about 3" square.

4. You can adjust the speeds if you turn the two screws on the top.

5. With the mixer off, start by turning them both the same amount of turns in the same direction and see how it affects the speeds. Start with 1/2 turn.

6. Be sure to keep track of the turns so you can return to the original start point if you have to. This will effect both the low and high speeds at the same time.

7. If you are going in the wrong direction, return to your start point and turn the opposite direction.

If this does not solve the problem, the circuit board is already malfunctioning and needs to be replaced.

Hope it helps.

Thank you for using FixYa.

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"

The mixer would not come up to the speed when speed lever is moved from off position to any other speed provided. The mixer would start spinning and then stops immediately. Any suggestions?


You either need to adjust the speed control switch under the rear dome or you need to replace the switch, I think you can find on YouTube videos on how to adjust speed control switch and the part is easily available on the internet. AND!! you can do this repair without a full tear down.

Knob for kitchaid stand mixer


I am assuming you mean the little black knob on the speed control has broken off. I will post the solution for that problem.
The speed control lever on KitchenAid mixers has a little black knob on the end (in some cases this may be white or gray). The knob is pressed onto the lever, so if the knob breaks off your only option is to replace the whole lever.
KitchenAid has a kit that will include all you need to replace the speed control lever. It even comes with instructions. Here is a link to the speed control lever kit on our website: http://www.mendingshed.com/kaleverkit.html

The lever kit includes the speed control lever (with knob), speed link, spring, instructions and a gearbox gasket.


The instructions will only walk you through how to hook up the speed control lever, so if you also need a little guidance in taking the mixer apart, and reassembling it please use the KitchenAid service manual. The manual will walk you through all of the repairs you may need on your mixer, including how to take the mixer apart and put it back together. Here is a link to the service manual: http://lib.store.yahoo.net/lib/mendingshed/kitchenaidservicemanual.pdf

Remember, The Mending Shed is a Authorized KitchenAid service center, we can help you with any repair needs for your KitchenAid appliances, plus all of the parts we carry are genuine KitchenAid brand.

KitchenAid mixer speed surges high and low uncontrolably


You can get the high speed back if you want to play with those three screws. there is a timing scheme for your mixer and it is set and adjusted by manipulating those 3 screws. The bottom center screw is for speeds 6 8 and 10. The best choice is to replace this switch, about $10 bucks on ebay.

Motor noise


It has been my experience with knocking kitchenaid is one of three reasons all related to the speed control of the mixer1 speed control board adjust speed screws2 speed Phase control board, needs replacing3 The motor governor behind the speed control board needs replacing
Speed board = $9.00Phase Board = $20.00Governor = $10.00Your time + one week for ordered parts asnd one hour to remove and replace.

all work is performed at the rear of the mixer and you need only a phillips #2 screwdriver, a pair of needle nose pliers, an 11/32 open end wrench (you will need this to adjust your speed control board after new install) and that's it. easy work all remove and replace. Oh! make sure that you pit some thermal paste behind the phase control board to avoid burn out.


But!!! before you buy parts and do all that, try adjusting the speed contol board first. Go here for a parts list for your model.


http://shared.whirlpoolcorp.com/product_literature/search_results.jsp?searchTerm=KV25G0X&siteCd=KAD&userType=Servicer


then go here for instructions on tuning the mixer speed.
http://www.youtube.com/watch?v=pUo_ZU5xh3o

if after you tune it you still get the knocking then use the parts list to order parts. two good parts sources are goodmans.com and mendingshed,com, they are reliable and have the parts in stock.

I have a Hobart KitchenAid Mixer Model K45SS and it runs fast on low (Surges speeds up and down)what is causing this problem


Hello Mayfix,

The problem with your mixer is the speed control switch, this switch is located at the back of the unit. It is usually black and has all of the wires coming into it, the Item # 1394070 and cost $27.95 it can be located at RepairClinic.com he is a link
http://www.repairclinic.com/Kitchenaid-Switch-Parts?z=100&gclid=CKSD5NriuKcCFUVqKgodIE2b_g

You will have to adjust after you install you will adjust the two screws at the top of the switch while the machine is running inorder to make sure that you are getting all the speeds. Be careful as there is a possibility of electrical shock if you touch the wronge thing.

Thank you for using FixYa.

The kitchenaid k5ss runs at high speed at every setting of the speed control. How is this adjusted?


This is a bad rheostat switch. You will need to visit a repair center to have this fixed or get the part you need.
