Maytag dryer AF error code

Dryer

Maytag dryer AF means restricted airflow — the exhaust path is blocked enough that clothes take longer to dry and the dryer may shut off heat to protect itself. On WED4815EW and similar electric models, a full lint screen, crushed flex hose, or blocked roof cap cause most AF codes before any sensor fails. Treat AF as a vent-cleaning job first, not a parts order.

How to fix AF

Pull the lint screen and wash it if dryer-sheet residue coats the mesh — vacuum the filter slot.
Disconnect the 4-inch vent hose behind the dryer and inspect for kinks, crushing, or lint packing inside the hose.
Check the exterior vent hood — the damper should swing freely and you should feel strong airflow when the dryer runs.
Remove lint from the blower housing opening if accessible from the back panel.
Run a timed dry cycle and confirm warm air at the outside vent — AF should clear once airflow is restored.

Call a pro when: Call a vent cleaning service for long roof runs, or if exterior airflow stays weak after cleaning the filter and hose.

Check: Clean the lint filter, then check the rear hose and outdoor vent flap for lint or a crushed duct.

Est. cost: $0–$0

PossibleLong or crushed vent run

Too many elbows or a crushed flex hose chokes airflow even after you clean lint.

Check: Run the dryer and confirm air is blowing outside. Shorten or replace crushed duct.

Questions about AF

How do I reset Maytag dryer AF?
