What this codemay mean.
A plain-language reading of the code — always confirm against your model’s documentation.
Mean
Restricted air flow: the lint screen or vent is clogged; the vent may be crushed, kinked or have too many turns.
Does F30 stop the dryer?
No. The dryer continues to run with the code showing, and touching any key clears it so the display goes back to the estimated time remaining.
What F30 means
Restricted Air Flow. Either the lint screen or the vent is clogged, or the vent is crushed, kinked or has too many turns. It is listed for commercial-grade residential Whirlpool dryers.
Checks to run
Lint screen: clean it.
Vent run between dryer and wall: look for a crush or kink, and for lint and debris.
Exterior exhaust hood: make sure it is free of lint and debris.
Vent layout: compare run length and number of elbows with the Installation Instructions for your vent type.
Test: start a Timed Dry heated cycle.
