Kitchenaid Speed 2 too fast, can't adjust it

Hello everybody!

I bought an KSM150 which was bought in the Unites States around 2005. For using it here in Germany I use a Converter from 230 V to 120 V which works perfectly.

My problem is, that speed 2 is nearly twice as fast as it should be, speed 2 , 6 and 8 are nearly the same and speed 10 is a lot faster. I tried to adjust it, what didn't work. So i bought a new phase control board and replaced the old one, sadly without an effect.

Do you think it's the speed control plate or could it also be the Mixer Motor Governor which causes the problem?

Thanks for your help,

Take a look at the speed control board and see if anything looks burned, The are also adjustment screws on the board:

Usually, replacement is not required.

#1. DISCONNECT FROM MAINS and undo the single screw at the top of the rear cover. The black plate being held in the picture above bears the 3 adjustment screws, which are secured by locknuts.

#2. To decrease the slowest speed, loosen the locknuts of the two upper screws and tighten the screws symmetrically, so the top edge of the black plate stays parallel to the case. The nominal free length of the screws plus nut is 10mm for 60 rpm, but you may have to reduce this.

#3. Replace the rear cover and screw, reconnect to mains and see what the minimum speed is now and DISCONNECT FROM MAINS AGAIN. If it is slow enough, TIGHTEN ALL 3 LOCKNUTS while keeping the screws from turning (loose locknuts are the probable reason for the trouble in the first place), replace the cover and retaining screw and then do a last check.

#4. If it is still not slow enough, go back to #2.

#5. Adjust the lower screw only if the top speed is wrong - after correcting the lowest speed.


It does sound as if the control board needs adjustment. Try downloading the following Service Manual which actually applies to the Artisan although it does not say so:

There are three schrews, 2 on the upper side of th speed control plate and one below. They can be adjusted. Check at the rotor , greasing in the coilspring could be dry.

I had some issue on this before, but lubricating the coil at the rotor to the speed control plate and fine adjustment of the three schrews allow me to adjust the speed again

I know you are converting 220v to 110v, but what is the FREQUENCY of the electricity in your German city? 50hz or 60hz? I know from personal experience that it is different, and eventually gave up on converting electricity for anything with a motor (especially clocks)
