Speed adjustment not working - KitchenAid 32685 Mixer

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

If the mixer is working on the other speeds, it needs adjustment to the speed control plate. See the Service Manual:

Hiya,

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

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

I hope this helps you!!

First the K45SS does not have a hall effect sensor. the pro series the epicurean seines and the pro series 5 use them, The K45ss system uses a phase control board a speed control plate and a governor for speed control. the governor rarely goes out the phase control board is a likely culprit but the system would work only in high gear if it was bad. I agree with the guest above in that it sounds like the retaining nuts on the adjusting screws of the speed control board have worked themselves loose and the adjustment screws themselves have vibrated out of proper position.

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.

then go here for instructions on tuning the mixer speed.

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.

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

You are not adjusting the screws correctly. All three screws (2 top left and right, and 1 bottom)
must all be adjusted. Here is how:

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

This problem could be due to a worn or broken speed governor. this part is located on the motor shaft of the unit and works by way of centrifugal force. This however when gone will usually make the mixers speed go up and down, not just one speed. The most likely cause of this problem is the main control board. if this has become faulty, it can make the mixer stop completely or in your case, run full speed when turn on. part number for the board is W10119326. this part can easily be changed by disconnecting all power and removing the back end cover. Once removed make note of the adjustment screws at the bottom of the board. As these are your motor speed adjustment screws, and can be very finely tuned. Once these and the spring has been removed. you can now replace the board. Hope this helps

Thanks

Yes it is compatible. You may also have a problem with the control plate
