What AF Means
AF flashes when the dryer detects restricted airflow through the exhaust system — the lint screen, door seal, or exhaust vent isn't allowing air to move through at the rate the control board expects.
Common Causes of AF
- Clogged lint screen (surface or embedded mesh)
- Door seal gap or damage
- Kinked or lint-packed flexible exhaust hose behind the machine
🔧 One Safe Check You Can Try
Clean the lint screen fully (not just the visible surface — the mesh underneath can clog too), and check that the door seal is seated properly — both are external checks that resolve a meaningful share of AF cases.
⚠ Why You Shouldn't Go Further Than That
- A vent run that's clogged further down the line, beyond what's reachable from behind the machine, is a genuine fire-safety concern and often needs proper vent-cleaning tools to clear fully.
- Restricted airflow that isn't actually resolved, just temporarily improved, lets heat build up inside the drum on future loads — a real fire risk worth taking seriously rather than dismissing after one cleaning.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
