Motor Speed Sensor (Tachometer)
In DC-driven KitchenAid mixers, the speed sensor utilizes a Hall Effect sensor to detect magnetic pulses from the motor shaft. If the sensor's internal circuitry fails or the sensor becomes dislodged, the control board loses the feedback loop required for Pulse Width Modulation (PWM) regulation. This leads to a safety lockout to prevent motor runaway or thermal damage.

Electronic Control Board
The control board is the logic center that interprets signals from the speed sensor. If the logic gate responsible for processing RPM feedback fails due to a voltage spike or component fatigue, the board will fail to drive the motor even if the sensor is functional. This board manages the specific torque curves required for commercial-grade kneading.

Carbon Brush Kit
While the motor is high-efficiency, it still utilizes carbon brushes to provide current to the armature. If these brushes wear down past the minimum threshold or develop glazing, the resulting electrical 'noise' and intermittent contact can mimic a speed sensor failure by creating erratic RPM data that triggers the control board's error state.
