Spark Ignition Switch Control Board 00629722

This potentiometer, also known as a spark ignition switch, sits behind a range or cooktop control knob and translates the rotation of the knob into electrical signals that regulate burner heat and ensure consistent ignition. It restores smooth, precise burner control when the original switch becomes unresponsive, creates dead spots, or causes the flame to fluctuate. Installation generally involves disconnecting power or gas as appropriate, removing the control knob and panel to access the switch, transferring each wire to the matching terminal on the new component, and securing it in place before reassembling the front controls.
