Amana Dryer AF — Restricted Air Flow
Amana Dryer · Error code AF
What AF Means
Air Flow restriction detected. The dryer senses low exhaust velocity from the blower, usually due to a clogged lint screen, filter, or vent duct.
Symptoms
- AF on display
- Clothes take multiple cycles to dry
- Dryer cabinet hot to the touch
- Cycle times automatically extend
Common Causes
Lint buildup on the screen restricts airflow — clean every load.
Lint accumulation in the duct or exterior vent hood is the most common AF cause.
Foil/vinyl ducts compress behind the dryer.
Stuck-shut flap or bird/rodent nest in the exit cap.
Lint slug or broken blower wheel inside the housing.
How to Fix It
- Clean the lint screen thoroughly — even if it looks clean, run water through it to check for fabric softener residue.
- Disconnect the transition duct and inspect for lint clogs.
- Brush out the full exhaust run from dryer to exterior hood.
- Verify the exterior vent flap opens freely when the dryer runs.
- Replace flexible foil duct with smooth rigid metal duct, keeping total run under 25 ft.
- Open the dryer and inspect the blower wheel for obstructions or damage.
