What is the purpose of the dryer drum seal and how can it be maintained to ensure optimal performance of the dryer?

The purpose of the dryer drum seal is to create a seal between the drum and the front or rear bulkheads of the dryer, preventing hot air and moisture from escaping. To maintain optimal performance, the dryer drum seal should be regularly inspected for wear and tear, cleaned of any debris, and replaced if necessary. This will help ensure that the dryer operates efficiently and effectively.
