Whirlpool dryer error AF – Airflow blockage
The AF error code on Whirlpool dryers indicates restricted airflow, which can lead to inefficient drying, overheating, and potential fire hazards. Proper airflow is essential to keep your dryer working efficiently and safely.
Causes of the AF error
- Clogged lint trap
A buildup of lint restricts airflow and reduces drying efficiency.
- Blocked vent hose
Kinks or obstructions in the vent hose prevent proper air circulation.
- Dirty or blocked external vent
The outdoor vent may be clogged with lint or debris, restricting airflow.
- Blower wheel issues
A malfunctioning blower wheel can hinder air movement through the dryer.
How to fix the AF error
- Clean the lint trap
Remove lint buildup after every load to prevent clogging.
- Inspect and clean the vent hose
Ensure it’s free from kinks and obstructions.
- Check the external vent
Clear away any debris to allow proper airflow.
- Examine the blower wheel
If the blower wheel isn’t functioning properly, a technician may need to replace it.
Pro tip
Schedule routine vent cleanings every 6-12 months to prevent buildup and maintain dryer efficiency.
