How to repair the dial on a Kenmore stand up mixer?

The mixer is almost certainly made by Kitchenaid. Kenmore stuff is just a brand name and the items are made by large reputable companies and badged Kenmore.

I found this;

Posted: 09/15/2011 Options I had a similar problem with my Kitchen Aid. The switch is not actually a switch but rather moves a lever that operates two things at the back of the mixer: 1) a simple lifting copper arm that makes a contact to provide power to the system (electrically this mixer is just on or off) and 2) The lever also moves the entire back control board forward and back. There are two long screws at the top of the control board that are spring supported to allow for this movement. There is a governor on the shaft of the motor that pushes against a plate in the center of the control board. The farther the switch moves the control board back the further back on the shaft the governor can go and the faster the machine can go. In my case the screws holding the control board had come loose allowing the governor to go all the way back (high speed) at the first click. Take the back cover off and see if the two top screws need to be adjusted (tighter and the mixer starts slower (or not at all) looser and is starts faster and the last click or two will not make it go any faster. Also check the copper arm to ensure it moves up and down on the first click of the switch properly. Also in my case the two nuts that hold the motor in place had come loose and were in the bottom of the cover so you may want to check for those. Ensure the mixer is unplugged before opening.

I agree with E Brian. There is no on-of switch as such, just a governor. In my case, like Jeanne the baker, the switch jumps on all by itself. The solution was quite simple. The little lever is held in place with a screw. If this screw is loose, the lever will not stay in the correct detent, as it is pulled forward by a spring. Tighten the screw, and the problem is solved. I was surprised by how old-tech the mixers are. The controls are electro-mechanical like I remember from school almost 50 years ago. I expect that the new ones are electronic.

I have to go up to 3 or 4 before the mixer will start

Does the mixer operate on the lower settings once you've got it going at the higher speeds?

If so the motor mechanism may need to be serviced (cleaned). OR it could be the switch mechanism is either 'dirty' (maybe with built up flour?) or has failed and needs to be replaced.

While UNPLUGGED, move the switch back and forth from OFF to full speed many times, if you have compressed air, blow that into the slot around (top & bottom) while operating the switch.

Set to OFF, plug it in the mixer and try it.

If that doesn't fix the problem, then consider having the mixer serviced or replaced.

KitchenAid Speeds are offset

Ideally you need to fix what's bent and that normally would involve splitting the cases to get at and repair or change the speed control lever. If you don't want to do that then removing the back cover and altering the adjustments and maybe bending the switch contacts may make it operate at both ends of the speed control.

Fails to run

The governor should move back and forth as the speed control goes from speeds 1 through 10. It's purpose is to push on the control plate in order to obtain the different motor speeds.

Mixer won't start. Fell on its side and on/off lever was bent. Straightened and it now moves back and forth as it did before. I took out the two black screws at the top which hold in magnets on...

Get A Copy of the Repair Parts List from
Make sure the Speed Lever and and the Speed Link are in place
and operating smoothly. The two Large black screws you are referring to
are the Motor Brushes Caps. The Carbon Brushes are keyed and
designed to be inserted into the Motor Housing but one way. If you
insert them in wrong, they will not make contact with the Motor Coils
and you mixer will never run.

All you have to do now is adjust the mixer speeds (if necessary):

Remove the screw holding the End Cover and locate the three screws from the Control Plate.
All three (2 top left and right, and 1 bottom) must be adjusted.

1. Loosen the lock nuts enough & Turn the 2 top screws clockwise until they cannot be turned
anymore. Leave the bottom screw alone for now.
2. Use a dab of white paint or paper whiteout to mark the positions of the Phillips screws.
3. Plug in your mixer and Set the speed selector to "Stir".
4. Turn each top screw One full turn couterclockwise (alternating between Left and Right)
Keep making one full turn at the time (for both left and right) until the motor starts running.
5. Put your hand near the Agitator shaft and allow it to brush your finger slightly. Use your
watch or clock and start counting the number of times the shaft touches your finger in
60 seconds. The correct count should be 60 RPM (Rounds Per Minute). If it is less
or more than 60, give each screw 1/4 turn counterclockwise or clockwise and start counting
again. Now tighten both lock nuts.
6. Set the speed selector to "6" and turn the bottom screw either clockwise or counterclockwise
to achieve a speed of 180 RPM.

For your reference, the planetary RPM's for the 5-qt. tilt-head Artisan Stand Mixer are as follows:
Stir speed - 60
Speed 2 - 95
Speed 4 - 135
Speed 6 - 180
Speed 8 - 225
Speed 10 - 280

Hi, the speed lever won't move. I have checked that the bowl is securely placed and adjusted the height of the beaters? Can you tell me what else might be the problem. I have only had the appliance...

The Speed Control lever is linked to the Speed Link mechanism, which in turn moves the
Speed Control Assembly to allow the motor to operate at different speeds.
Get a Repair Part List from for your particular model to see how it works.
As you select different speed setting, the Speed Link simply moves forward or backward,
thus pushing the Speed Control Assembly back and forth.
If you cannot move the Speed Control lever, means that the Speed Link is somehow bent
or out of place. Remove the Motor Housing and the End Cover and check it out.

Kitchenaid mixer ksm160 stop working after a flash appear  in the rear of motor

We have a 10 month old KSM150 and the same thing happened. I called to have it fixed under warranty and their 'Hassle Free' replacement warranty is anything but! The spped controll leaver slides the electrical switch back and forth at the very back of the unit. Looks like there are 2 small metal spring connections that maintain contact when things are working properly. There is one screw at the top of the small dome at the back; removing this screw gives you access to this. I bet you will find that these 'spring connections' have come loose from the vibrations and are causing a short with the exposed electrical terminals. As far as I am concerned that is a design flaw and poses a serious danger of eletric shock or fire and KitchenAid shoud fess up before someone with the wrong breaker in their home gets hurt. I am mad as hell.

Speed of mixer

does the motor still run or does it slowly start to get less loud? or is the beater assembly that dosnt work? two different issues. if the motor runs but dosnt beat then its the planitary gears that are ground out and need replacing. if the motor slowly dies out then you need to replace the motor.

The tilt button is not working

Okay, we just figured this out ourselves.
There is a little hole on the neck of the mixer, where the mixer motor meets the neck. While pushing the tilt release button, stick a small screwdriver into the hole (it will not go far) and pry the latch upward. While holding the latch up and the tilt button, have someone pull up on the motor while holding down the base. It might take a little muscle, but after that, the motor will be able to tilt back and forth like it did before it got stuck. If you are the one holding the tilt button and latch, please wach your finger so they don't get pinched when the motor swings up.
