The Whirlpool WP9763762 Range Surface Element Infinite Control Switch regulates surface burner heat to support precise and consistent cooking control. This component is an electrical control switch that adjusts power levels to the range’s surface element by cycling the current on and off based on the selected setting. By varying the duration of power flow, it allows users to fine-tune temperatures for simmering, boiling, or frying. Designed to integrate smoothly with the range control panel, it helps ensure responsive operation and predictable performance. Replacing a worn or malfunctioning control switch can restore accurate heat adjustment, improve cooking results, and support safe, reliable operation of the range during everyday use.
