The bad sparking can be several different things. The bad sparking at contact points or burned contracts on the switch can be caused by a faulty phase control or wrong wiring. Open the mixer, check wiring, if that is correct remove an replace the phase control board. If the bad sparking is at the motor brushes this can be caused by worn motor brushes, rough commutator, faulty armature or shorted motor field. First remove the brushes and check that they are not worn to less that 5/16'. Replace with new brushes if excessively worn. If Brushes are fine remove and check armature. you will most likely have to replace the motor/armature assembly. Thank you, Colleen MendingShed.com 800-339-9297
It is possible that the motor is faulty and weak and the shake makes it contact to work . This is due to failure of the commutator or the brush and must be replaced. The spark is an indication of this fault as the brushes are weak to contact. Adjustment of the brush tension spring must help a bit but replacement is the best solution.

Hi from the Philippines and welcome to FixYa, I am Kelly
Is it just the power whisk or all attachments that do not rotate? On the A701A there is a clutch and spring fitted to the gearbox. (Spring loaded clutch) There is a pin in the cover that actuates the clutch. If the pin is broken or come out of the cover then the front of the machine will not work. (you may have to have someone fabricate a new pin!) If the clutch spring has broken you will experience the symptom you described also.
Hi JIM, Happy New Year! From the symptoms you describe of your sister’s mixer it appears there are a couple of issues that need to be addressed. Issue #1, when your sister found the loose governor counterweights that should have been a clue that the governor needs to be replaced. The counterweights should not come off the governor.From your description that you “put everything back together, the actual mixer runs (but a little too fast on slow)” is an indicator that although everything went back together, the governor is still not functioning properly, so it still should be replaced. Issue #2, which concerned you more, was “the arcing that is constant on the actual contact points that turn the motor on and off.” The contact points you refer to are the mixer’s electric motor brushes, and although arcing continuously occurs (that’s why the mixer head gets hot during heavy usage) under normal operation, it may be time to inspect and replace the mixer’s brushes; the more worn the brushes, the greater the arcing, which makes it more noticeable while more heat is produced. Before going too much further, be sure to have your Parts List Manual on hand, too.If you don’t have the original you can easily download a PDF version from the KA website: (http://www.kitchenaid.com/flash.cmd?/#/page/home). Click on Customer Care>Locate Manuals& Guides> and enter the 6 character model number, KSM150P and select the file: KSM150PSWH0.pdf (773.44 KB) listed for your model that appears under Parts List (61). Check to see that this matches your sister’s mixer model. Turn to pages 8 & 9, titled “Motor And Control Parts” which provide an exploded view for the disassembly and reassembly of the mixer’s motor and electrical control components.Locate Illus. Nos. 29 and 19, Governor Assembly and Carbon Brush, respectively.These are the parts that I would replace – one governor and two carbon brushes. As far as parts go, here are four potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com.Prices for the same part can vary widely between vendors, so do your comparison shopping. Here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer.
Between these three websites and their excellent pictures and descriptions and your Parts List manual, you should now be able to completely disassemble and reassemble your mixer. If you feel troubleshooting and repairing is beyond your capability, then I would seek out a local small appliance repair shop in your area. KA Customer Care can give you names of local KA authorized repair shops in your area, but you can also do an online search to supplement what KA may provide you. Call to explain your circumstances and find out their hourly rate and get an estimate of what they think it would cost to repair your mixer. Also, always obtain three or more estimates – do some comparison shopping. Good luck and have fun. I hope this helps.

ECARRERO2004 - Those 'magnets' you removed from the sides of your mixer are the electric motor brushes that provide power to the commutator/armature assembly so your motor runs. Did you remove the brushes to replace them or were you just inspecting them? I'd suggest removing them again and making sure the contacts are facing in the right direction to contact the commutaor. The concave contact face should be resting completely on the comutator. If you've turned it 90 degrees too much, it wont' seat properly and you'll get no 'juice' to the electric motor so it won't start. I hope this helps - Howard, Burke, VA If this solution has helped you, please rate it. hslincoln
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
They are junk! If you are hands on savvy look for my other posts on disassembly. Then, make sure grease is not seaping into the motor area and then clean every contact using contact cleaner. Filing the "points" is also worth a try. Lately, you can't buy one of these that isn't junk. Have you seen all the posts??
