The Star Mfg 8002 Speed Control Potentiometer provides precise motor speed adjustment to support consistent operation in commercial foodservice equipment. Manufactured by Star Manufacturing, this 120V potentiometer features white wire leads, an integrated diode, and a no-positive-off design for continuous control. It works by varying electrical resistance within the circuit as the control is turned, which adjusts the voltage supplied to connected motors and regulates their operating speed. This controlled adjustment helps maintain steady conveyor or fan movement in compatible appliances such as toasters, broilers, and ovens. Its durable construction and reliable electrical performance support accurate equipment control, smoother operation, and dependable day-to-day functionality.
