Hello Brenda,

You need to adjust the speed control switch at the rear of the machine and you can find a video on this exersise on YouTube.

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.

The K45SS is very similar to the 5-qt. tilt-head Artisan Stand Mixer.
You need to adjust the mixer speeds. Obtain a copy of the K45SS Repair Part List from Kitchenaid.com. 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

Hiya,

I am sorry to hear you are having problems with your speed on your mixer.

I have added a link below for a help video on adjusting the speed on your mixer:

I hope this helps you solve the problem!

Your motor needs to be replaced. The speed setting should be able to be set from the start, and if it will not slow down or change speeds, the motor has been over-heated and will need to be replaced. The only quick fix for this is to bypass the speed setting, and change the brushes on the motor. If you do not know how to do this, ask a serviceman to change the brushes only. Brushes usually run about $30 to repair. Although, you will only have one speed.

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

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.

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.
