Quick answer
The F4E3 restricted air flow code on Whirlpool dryers and what the manual tells owners to check.
Model note: Whirlpool reuses codes across series and model years, so F4E3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this codemay mean.
A plain-language reading of the code — always confirm against your model’s documentation.
Mean
F4E3 (Restricted Air Flow) indicates that the lint screen or vent is clogged; on laundry towers it names the main heater.
An F4E3 (Restricted Air Flow) code tells you the lint screen or vent is clogged. The vent may also be crushed, kinked or have too many turns. This is the meaning for dryers and commercial-grade residential dryers.
The dryer keeps running while the error is present. Touch any key to clear the code from the display and return to the estimated time remaining.
Try the following
Clean the lint screen.
Check whether the vent run from the dryer to the wall is crushed or kinked.
Make sure that run is free of lint and debris.
Make sure the exterior vent exhaust hood is also free of lint and debris.
Confirm the vent system stays within the recommended run length and number of elbows for your vent type; the Installation Instructions have the details.
Select a Timed Dry heated cycle and restart the dryer.
If the message persists, have the entire home venting run cleaned and contact a venting specialist.
Laundry towers
On laundry towers the listing is different: the potential cause is the main heater. Remove power from the dryer for one minute (the washer needs 5 minutes) and schedule service if the code returns.
Related codes
F4E4 is about low or no line voltage, F4E1 about the heater or heater relays, and F4E2 about the main heater.
