Why airflow warnings matter
Dryers depend on moving hot, moist air out of the appliance. Restricted airflow can make cycles longer, raise cabinet temperatures, and stress thermal safety parts.
The lint screen is only one part of the path. A clean screen does not prove the wall duct or outdoor hood is clear.
What to check before resetting
Check the lint screen, duct behind the dryer, outdoor vent hood, and whether the room feels unusually hot during operation. If the dryer is gas-connected, do not move it unless you can do so safely.
Use air-only or stop conditions when smell, heat, or repeated codes suggest risk. Do not keep running timed heat to see whether the warning returns.
- Clean the lint screen.
- Look for crushed or kinked flexible duct.
- Confirm the exterior flap opens.
- Stop if there is burning smell or excessive heat.
When a reset is reasonable
A single reset after clearing a visible vent issue can confirm whether the warning was temporary. If the warning returns, treat it as an unresolved airflow problem.
Model-specific diagnostics may include sensor or thermistor checks, but those belong in official service material or technician work.
