The Samsung DA97-16990A Refrigerator Freezer Door Gasket helps maintain efficient cooling by creating a secure seal around the freezer door. This replacement gasket is designed to fit along the door edge, preventing cold air from escaping and reducing the entry of warm outside air into the freezer compartment. It works by forming a tight magnetic seal when the door is closed, supporting stable internal temperatures and consistent appliance performance. A properly functioning gasket can help reduce energy loss, limit frost buildup, and improve food preservation conditions. Suitable for compatible refrigerator models, this component offers a practical solution for restoring an effective door seal and supporting the long-term efficiency of the appliance.
