Whirlpool Dryer Error Code AF – Airflow Restricted

What Does This Error Code Mean?

The Whirlpool dryer error code AF stands for “Airflow Restricted.” In simple terms, your dryer is not getting enough airflow to operate efficiently. This means the machine is struggling to push hot, moist air out through the vent system. Proper airflow is essential for drying clothes effectively. When airflow is blocked or reduced, heat and moisture get trapped inside the dryer. As a result, drying times increase, clothes may remain damp, and the appliance may overheat. If your Whirlpool dryer is not working as expected and showing the AF error code, it’s usually a warning that the ventilation system needs attention. This is one of the most common issues identified during Whirlpool dryer troubleshooting.
