Maytag Dryer Error Code AF — Restricted Airflow
What this means
The AF error on Maytag dryers (which use the Whirlpool platform) indicates restricted exhaust airflow. This is a fire hazard. Clean the lint filter, exhaust duct, and exterior vent.
Alternate codes: L1
Step-by-step fix
3 stepsClean the lint filter
Remove and clean the lint screen. Wash with soap and water if coated.
Dryer sheets and fabric softener coat the mesh over time, reducing airflow even when the screen looks clean.
Clean the exhaust duct
Disconnect the duct and clean the entire run with a vent brush or vacuum.
Flexible foil ducts trap more lint than rigid metal — consider upgrading.
Check the exterior vent
Go outside and verify the flap opens and airflow is strong when the dryer runs.
Accumulated lint in the vent hood is a common blockage point.
When to call a professional
For long or inaccessible vent runs, hire a professional vent cleaning service.
