Variable Speed Potentiometer Assembly
The potentiometer is the electromechanical component responsible for speed regulation; a loose knob indicates the mounting bushing has detached or the internal shaft-to-wiper coupling has failed. High-vibration environments in high-performance blenders often lead to the loosening of the retaining nut or structural fatigue of the potentiometer housing. Replacing the assembly restores both the mechanical mounting integrity and the precise resistive signaling required for the control board.
