The Lint Chute Seal is an OEM part for Whirlpool dryers. This seal is designed to fit around the lint chute, ensuring a tight seal that prevents lint from escaping back into the dryer cabinet. The primary function of this seal is to contain lint within the chute, directing it to the lint filter and ultimately enhancing the dryer's efficiency by improving airflow and reducing the risk of lint buildup that can lead to overheating. Causes of a bad Lint Chute Seal include wear and tear over time, exposure to high temperatures, or damage from regular use.
