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, Alex
Take a look at the speed control board and see if anything looks burned, The are also adjustment screws on the board: KitchenAid KSM150PSER Speed Control Plate Replacement
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)
