The small radiant surface element with limiter is located under the main cooktop. When the heat temperature is selected, the element will heat up and supply the desire heat to the cooking area on top of the range. If the surface element will not heat, you will need to replace it. It has an outside diameter of approximately 7” and is a genuine OEM part sourced directly from the manufacturer. Before starting the repair, make sure the element is cool and the power is disconnected from your range.
