The Frigidaire 318372017 Insulation reduces heat transfer around the range oven to support consistent cooking temperatures. This replacement insulation material is positioned within the oven’s cabinet area to retain heat inside the oven cavity and limit heat transfer to surrounding components. Proper insulation can support more stable internal temperatures and reduce unnecessary heat loss during cooking. Damaged, compressed, or missing insulation may affect heat retention and allow excess heat to reach areas outside the oven cavity.
