The Whirlpool WPW10139457 Dryer Door Seal forms a barrier around the dryer door to reduce warm air leakage during drying cycles. Installed along the door opening, it creates a fitted contact surface when the door closes, supporting proper closure and airflow within the drum. A worn, cracked, or damaged seal may allow warm air to escape and reduce drying efficiency. Replacing the faulty seal restores the intended fit around the door opening and supports consistent drying performance. This replacement part is designed for compatible dryer models and provides a practical solution for addressing a damaged door seal without replacing the entire door assembly.
