Guide :Food Mixers : KSM50PR Professional Series Stand Mixer
Mixer starts running on selected speed then speeds up & quits
Then motor has plenty of power, and the transmission is working properly, but as soon as we start needing bread the motor speeds up to full speed then quits. The control can then be cycled to stop and the machine started over where it will repeat the same thing. the machine was purchased new just over a year ago. Our family has four other of your machines, one is way over ten years old and none have had this experience. We love our Kitchenaids and regret this trouble.
