Schematic illustration of a typical dryer — not your exact model.

Before you start — unplug the dryer, and on a gas model shut off the gas supply. Let it cool first — the drum, heater and exhaust can be hot. If a step involves the heating element, wiring, or opening the cabinet and you're unsure, stop and call a qualified technician.

Step-by-step fix

1Clean the lint screenPull out and clean the lint screen; wash off any softener film with warm soapy water and dry it fully.
2Check the outside hoodRun the dryer 5-10 minutes and feel the airflow at the outdoor exhaust hood - it should be as strong as a hair dryer on high.
3Clear the ductDisconnect and vacuum lint from the full length of the vent duct and the exterior hood.
4Straighten the hoseMake sure the transition hose behind the dryer is not crushed or kinked.
5Review the vent runConfirm the duct length and number of elbows meet the installation instructions; shorten or reroute if excessive.
6Clear and retryTouch any key to clear the code and run a Timed Dry cycle to confirm normal airflow.

Still showing AF?

If you’ve worked through every step and AF keeps returning, an internal part likely needs testing and replacement. That’s a job for a qualified appliance technician, who can measure the suspect part against the service-manual spec before replacing it.
