Sometimes can be caused by running too fast on the lower speeds. Should be 13 to 15 revolutions in 15 seconds on speed 1 then a slight increase only on speed 2.

SOURCE: KitchenAid K5SS mixer speeds up beyond set speed.

I have the same mixer and I believe your problem is the governor that is on the back of the motor. You can figure it out by downloading the repair manual here:http://store.mendingshed.com/kitaidparts.html The manual has all the info you need; including a troubleshooting section. The governor is availible from the the same site here:http://store.mendingshed.com/kagovernor.html What tipped me off on my K5SS was looking at the governor as it ran and I could see it moving back and forth; not steady like it should. Good luck!

ok so the set-up looks sortof like this (lets hope the formatting of this website/your computer doesn't mess it up...)

  A
A is the rivet holding the arm to the plastic body B is the contact with a little tab. C is the copper arm D is the arm's contact
there is a copper arm (C) that has a contact on one end (D).  If this contact is ALWAYS open (should only be open when mixer is off) it is either bent (carefully reform) or has come loose at the rivet marked A.  On mine, the rivet at postn. A had come loose, i simply rotated it so that the contacts touched and super-glued the copper to the plastic (which should be rivited).
Since the copper was not discolored, I knew that the temps should not be too high for the super glue to handle (not in my opinion anyway).

It could be the phase control, or it could be that the governor assembly or associated spring is missing or malfunctioning.

Pull the back off and there will be two screws at the top of the Speed Control Plate and a 3rd screw at the bottom. Tighten the top two screws down. bakerboy49203@yahoo.com. Let me know if it works.

Here is how your speed control works:

Speed Control
The speed control of the mixer is attained through the use of a governor assembly mounted at the rear of the control plate assembly.
The electrical circuit is made and broken by the action of the fly ball governor revolving against the control plate.
When the switch lever is moved to an ON position, the position of the control plate with respect to the governor is changed by the action of the switch lever.
Thus, when the control plate is set close to the governor, a relatively low speed of the motor causes the governor to make or break the mixer’s electrical circuit through the control plate.
When the control plate is set farther away, a greater motor speed is required before the governor starts breaking the circuit.
The action of the governor is such that the speed of the motor will remain constant for a given setting of the control plate within certain loads.
After certain loads have been exceeded, the speed of the motor will drop to meet the torque requirements of the given load.
Speed is controlled by the governor and the control plate in conjunction with the phase control.

TRIAC RMS VOLTAGE
BOTH CONTACTS OPEN - 40 VOLTS
ONE CONTACT OPEN - 80 VOLTS
BOTH CONTACTS CLOSED - FULL VOLTAGE
NOTE: The triac regulates the power the motor sees depending on control board contacts.
A device called a triac is a part of the phase control circuit.
This device determines the amount of power the motor sees dependent upon the condition of the control board contacts.
If both contacts are open, about 40 volts RMS is applied to the motor and about 80 volts is applied when either contact is closed and the other is open.
When both contacts are closed, the triac is full on; consequently, full power is applied to the motor. In this way, the speed is controlled.
If the mixer motor begins to run too fast for a
particular speed setting, one or both contacts open, which cuts back on the voltage the motor sees, thus slowing it up.
If the motor operation becomes too slow, one or both contacts will close, applying the needed voltage to the motor to sufficiently increase motor speed.
This is always accomplished through the triac.
The control plate contacts control the triac, and in turn, controls the amount of power supplied to the motor.

The control Plate for your mixer is PN
W10119326

If your not good with tools / meters or tedious repairs do NOT attempt this yourself.

325 k5ss mixer stir speed not working, but works in all other gears


First congrats on the great mixer that you have. next the pro 6 or professional 600 series mixers are of an entirely different design than the one that you have even though they are both bowl lift. Do you really need 6 quarts capacity? The pro series is a 575 watt mixer BTW, and it will have more power available to you IF you are doing bread or a lot of food grinding, if that is a requirement that you have then the 6 / 600 series is the better suited mixer but if all you are doing is general medium to light mixing duties then fix and keep the K5SS it a great machine,

Mixer has lost all speeds, only works when moving the lever back and forth. The mixer is about 9 years old.

Adjust the mixer speeds:
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

Only works speeds 6-8. Turns off when moving knob to lower speeds. Tightening two screws in the back of the mixer above the power cord changed the working range from 4-6. Any ideas?

When you said "the speed switch doesn't want to stay in the off position", you meant to

switch physically cannot be moved to the OFF position"?

The speed control doesn't work well


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
