Dryer runs but clothes take a very long time to dry; display shows AF (restricted airflow) error.

Safety First: Unplug the dryer before inspecting the venting. If it is gas, also shut off the gas supply valve.

• Step 1 – Clean the lint screen: Remove the lint filter and clean off all lint with your fingers or a soft brush. Wash with warm soapy water if coated with fabric softener residue, then dry completely and reinstall.
• Step 2 – Inspect the vent hose: Pull the dryer away from the wall. Check the flexible vent hose for kinks, crushing, or tears. Straighten any sharp bends. Replace with a rigid or semi-rigid metal vent if you currently have plastic or foil venting.
• Step 3 – Clear internal venting: Disconnect the vent hose from the dryer outlet. Use a vacuum with a crevice tool or a vent brush to remove lint from the outlet duct on the dryer and from the hose itself.
• Step 4 – Check exterior vent hood: Go outside and inspect the vent hood. Remove any lint buildup, bird nests, or debris. Make sure the damper flap opens freely when you run the dryer on air-only (temporarily reconnect power for this test, then unplug again).
• Step 5 – Verify vent length: Compare your vent run to the Maytag installation manual. Excessive length or too many elbows can trigger AF. Shorten or simplify the run if possible.
• Step 6 – Test operation: Reconnect the vent, restore power (and gas if applicable), and run a timed dry cycle. If AF persists after thorough cleaning and vent correction, the internal blower housing or outlet duct may be restricted and should be inspected by a technician.
