The Frigidaire 5303937182 upper felt seal helps maintain proper airflow and heat retention inside the dryer for efficient operation. This component is designed to line the drum edge, creating a seal between the drum and the front panel. It works by reducing air leaks and preventing clothes from getting caught in gaps during rotation. The included adhesive backing allows for secure and straightforward installation. Made for compatibility with select dryer models, it serves as a practical replacement when the original seal becomes worn or damaged.
