Error codeF30
ApplianceDryer
Restricted Air Flow is how Whirlpool labels F30 on its commercial-grade residential dryers. Either the lint screen or the vent is clogged, or the vent has been crushed, kinked or given too many turns.
The dryer keeps running
Drying is not interrupted. Touching any key wipes F30 off the display and brings back the estimated time remaining.
Work through the air path
Empty and clean the lint screen.
Inspect the vent between dryer and wall for a crushed or kinked spot, and for lint or debris.
Inspect the exterior exhaust hood for the same.
Set the vent layout against the Installation Instructions for your vent type: they give the recommended run length and number of elbows.
Start a Timed Dry heated cycle to test.
No change
A venting specialist should clean the whole home venting run.

F31: low or no line voltage, a power issue rather than airflow
Once the venting is cleared and F30 still returns, contact us at (415) 687-4102 about Whirlpool dryer repair in San Francisco. Bring the code, the model number and your list of vent checks.
Model compatibility: Whirlpool reuses codes across series and model years, so F30 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
F30 means restricted air flow: a clogged lint screen or vent, or a vent that is crushed, kinked or has too many turns.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
