The General Electric WB04T10086 Range Oven Door Gasket helps maintain proper oven temperatures by creating a secure seal around the door. This flexible gasket fits along the oven door frame and works by preventing heat from escaping during baking or roasting cycles. By sealing in heat, it allows the oven to reach and maintain set temperatures more efficiently while protecting surrounding components from excess heat exposure. It is commonly replaced when the original gasket becomes worn, torn, or compressed over time. Installing a new door gasket supports even cooking results, improves energy efficiency, and helps ensure the oven operates safely and consistently during everyday use.
