The Whirlpool WPW10490037 is a replacement knob developed exclusively for Whirlpool ranges and ovens. The knob has markings and a turning mechanism that correlate to many settings, including burner level, oven temperature, and broiling mode. You can choose your preferred setting and modify the oven or cooktop's intensity by turning the knob. If your original knob is missing, worn out, cracked, or broken, this replacement is perfect for you. Your range or oven must have a working knob in order to operate safely and correctly. A damaged knob can make it difficult or impossible to modify settings, potentially resulting in uneven cooking or hazardous conditions.
