Maytag Dryer Error Code F30 — Restricted Airflow
What this means
The F30 error code indicates the dryer's airflow sensor has detected restricted exhaust airflow. This is most commonly caused by a clogged lint screen, a blocked or crushed vent duct, or excessive lint buildup in the vent run. The dryer will continue to operate but with reduced efficiency and longer drying times. Restricted airflow is a fire hazard and should be addressed promptly.
Alternate codes: F-30
Step-by-step fix
4 stepsClean the lint screen
Remove the lint screen and clean off all accumulated lint. Wash the screen with warm soapy water if it has residue buildup from dryer sheets.
If water does not pass through the screen easily, residue is reducing airflow.
Inspect the vent duct
Disconnect the vent duct from the back of the dryer and check for lint blockages, kinks, or crushing.
Flexible foil ducts crush easily — consider upgrading to rigid or semi-rigid metal ducting.
Clean the entire vent run
Use a vent cleaning brush kit to clean the vent duct from the dryer to the exterior wall outlet. Vacuum any loosened lint.
Professional vent cleaning is recommended at least once per year.
Check the exterior vent hood
Go outside and verify the vent hood flap opens freely. Remove any bird nests, debris, or lint blocking the exhaust outlet.
A vent hood with a screen or cage can trap lint — replace with a louvered hood.
When to call a professional
If you cannot access the full vent run (such as vents routed through walls or ceilings), hire a professional vent cleaning service.
