Maytag Dryer Error Code AF
Exhaust airflow below sensing threshold
Common Causes
- 1Packed lint blanketing the exhaust path
- 2Fabric-softener film sealing the lint screen mesh
- 3Kinked or crushed transition hose behind the dryer
- 4Snow, nesting, or a stuck flapper at the wall cap
A choked dryer vent is the leading cause of residential dryer fires. Clear the full duct run at least once a year.
Step-by-Step Troubleshooting
- 1
Pull the lint screen and scrub it under running water — an invisible softener glaze can choke a screen that still looks clear
- 2
Separate the transition hose at the bulkhead and feel inside for a felted lint plug near the first bend
- 3
Brush the rigid duct end to end out to the wall cap, working a vent brush the whole run
- 4
Push the exterior flapper open by hand and clear packed lint, leaves, or a bird nest lodged behind it
- 5
Tally the duct as equivalent feet — dock five feet per elbow — and reroute anything past the 25-foot ceiling
Pro Diagnostic Tip
The AccuDry board raises this fault when tumbled air cannot leave fast enough, and a smothered duct is the number-one dryer-fire ignition path. Upstairs laundry closets in the valley almost always run long, elbow-heavy vents that blow past the equivalent-length limit, so a booster fan or a shorter reroute is the durable fix, not just one more screen cleaning.
