Zachary December 10, 2015 for Model Number KSM150PSPT0 Okay - first off I did a dumb thing. Really dumb. I was trouble shooting speed problem with the back of the mixer off and forgot to unplug the mixer when I reached in with a small wrench to tighten the back plate. I accidentally touched the lower black wire while the wrench was on the nut. Pow! Sparks, then no response from the mixer. I just replaced the phase board and still no response. What do you suggest? I really need to get this working so my wife can make Christmas cookies.
1 Answer Zachary, You will want to replace the governer WPW10330804 and the control plate WPW10119326. Read More...
Ayesha August 20, 2014 for Model Number 5KSM156PSECA Hello can you please help. Why does the governor break on the mixer?
1 Answer Hello Ayesha. As with anything mechanical, parts do fail. We can not tell you why other than normal wear. Thanks. Read More...
Alfie July 18, 2014 for Model Number KB26G1XOB Motor seems to run fine but shuts off after appx. 8 seconds. only one speed. changed the speed selector switch no joy. any ideas would be appreciated. I am not incredible dumb when it comes to electricity US Navy electrician turned civilian. Thanks Alfie.
1 Answer Alfie, The most likely cause for the unit shutting down after 8 seconds and only having one speed would be a faulty hall effect sensor WP9706648. If the sensor checks ok then the motor is faulty and would need to be replaced. Read More...
Mike April 10, 2013 for Model Number Kitchenaid Mixer KSM5 The motor is making a loud griding noise. I have it apart with no gears attached and no load. The motor turns good but makes the noise. Governor? Bearings?
Joe H September 08, 2012 for Model Number KSM90WW Does not work at all, is there a wiring troubleshooting diagram on it to see if it is wiring or motor problem?
James S. December 22, 2011 for Model Number K5SS Kitchenaid The mixer is moving too fast in the stir mode. Can this be caused by the governor.
1 Answer Hello James. Yes, if the governor WPW10330804 is bad, it can cause problems with the motor speed. Hope this helps. Read More...
Frank June 23, 2011 for Model Number ksm90 Can the governor assembly cause the mixer to run at one speed?
1 Answer Hello Frank. Yes, the governor assembly WPW10330804 can cause the machine to run at one speed. Also, the phase board WPW10325124 can cause this as well. 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. Hope this helps. Read More...
