Kenmore Dryer Error Code F30 — Restricted Outlet Airflow
What this means
Error F30 indicates the dryer has detected poor exhaust airflow. This is typically caused by lint buildup in the vent system, a crushed or kinked vent hose, or a blocked exterior vent cap. Restricted airflow causes longer drying times and can be a fire hazard.
Step-by-step fix
4 stepsClean the lint filter
Remove and thoroughly clean the lint screen.
Check the vent hose
Disconnect the vent hose from the back of the dryer and check for lint blockages.
Clean the entire vent system
Use a dryer vent cleaning brush kit to clean from the dryer to the exterior vent. Vacuum up loose lint.
Professional vent cleaning is recommended annually.
Check the exterior vent cap
Go outside and verify the vent cap flap opens freely and is not blocked by debris or a bird nest.
When to call a professional
If you cannot access the full vent run, a professional dryer vent cleaning service can handle it.
