Direct answer
On the covered Whirlpool dryer, F4 E3 means Whirlpool names restricted air flow — their page states the lint screen or vent is clogged, and that the vent may be crushed, kinked or blocked. First, clean the lint screen and inspect the full vent run to the outside.
Definition versus diagnosis
The display names a detected condition—not an automatically failed part.

- Displayed code or documented alias: F4 E3

What it does not cover
- ×Another product type or original-manufacturer platform
- ×A visually similar but different code
- ×Internal live electrical, sealed-system, gas, battery-cell or control-board repair
Match every character and the exact product
ReversiblePhotograph the complete display and product label. This record covers F4 E3 on Whirlpool electronic-control dryers. Code availability varies by model and fuel type; a gas dryer and an electric dryer of the same series do not display the same set of codes.
Preserve the failure state
ReversibleClean the lint screen and inspect the full vent run to the outside. Record the operating stage, recent change and what still works before clearing the message.
Correct only the documented fault domain
ReversibleClear the restriction; a blocked vent is a fire risk, so do not keep running the dryer with the code present. Whirlpool documents these checks for this code: is the Lint Screen or Vent Clogged; and does the home venting line need to be cleaned or tested. Work them in that order and correct only what you actually find.
Verify once, then respect the service boundary
ReversibleRepeat only the shortest safe action that reaches the original stage. If F4 E3 returns, stop repeated resets and use model-specific manufacturer support.
