The Whirlpool WPW10208653 Insulation reduces heat transfer from the oven area to surrounding range components. This replacement insulation is positioned around designated areas of the oven cabinet, where it acts as a thermal barrier to retain heat within the oven and limit heat exposure to nearby surfaces. Proper insulation supports more consistent oven temperatures and reduces unnecessary heat loss during baking and cooking. Damaged, compressed, or deteriorated insulation may contribute to excessive heat around the range and inconsistent temperature retention.
