Amana Dryer AF — What It Means & How to Fix It
Also shown as Check Vent on some models.
Restricted airflow — AF (or 'Check Vent') tells you the dryer senses clogged venting that's slowing drying.
What this code means
AF is Amana's restricted-airflow code, also shown as the 'Check Vent' light on many models. It means the lint screen or the vent system is clogged, crushed, kinked, or has too many turns. The dryer keeps running, but drying takes longer and the heater works harder against a blocked vent. Amana's checks are: clean the lint screen, confirm the vent from dryer to wall isn't crushed, and confirm the outside hood is clear.
AF and 'Check Vent' are documented on Amana's own dryer error-code page; the Whirlpool-family platform labels the same airflow fault AF on dryers with shared electronics.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Lint screen clogged | Very common | Yes — clean each load |
| Vent run crushed, kinked, or too many elbows | Common | Yes — straighten the path |
| Lint buildup inside the vent run | Common | Yes — vacuum the run |
| Outside exhaust hood blocked | Occasional | Yes — clear the hood |
What you can try yourself
- Pull out the lint screen and clean it thoroughly before every load — this clears AF in most cases.
- Check the vent run behind the dryer: if it's crushed against the wall or kinked, reposition it.
- Run the dryer for 5–10 minutes and hold your hand under the outside hood — airflow should feel like a hair dryer on high.
- If airflow is weak, vacuum the vent run and hood, or hire a vent-cleaning service for a full-length clean.
- Restart on a Timed Dry heated cycle; AF should clear once airflow is restored.
When to call a technician
- The venting looks crushed or packed with lint — a blocked vent is a lint-fire risk, so fix it before running again.
- Clothes come out hot and damp even after the vent is cleared — the heater or moisture sensor may need attention.
Typical professional repair cost: $0 for DIY cleaning; professional vent cleaning runs about $150–$300
Frequently asked questions
Is it safe to keep drying with AF lit?
The dryer will still operate, but a blocked vent makes it work harder and is a lint-fire risk over time. Clear the vent rather than ignoring the light.
Does a kink matter on a short vent run?
Yes — even short runs need a straight, clear path. Amana lists crushed or kinked venting with too many turns as a cause of AF regardless of length.
