How to Enter Diagnostic Mode on a Whirlpool Dryer

Whirlpool dryers display F-codes on digital models; diagnostic entry is a button sequence from the tech sheet inside the console.

Step-by-Step: Whirlpool Dryer Diagnostics

  1. 1

    Digital models display F#E# codes automatically when a fault occurs.

  2. 2

    The diagnostic entry on most consoles: press and hold a button (commonly the first button used to start diagnostics per tech sheet) or press a 3-button sequence three times — the exact pattern is printed on the tech sheet inside the control console or behind the lower access panel.

  3. 3

    In diagnostics, stored codes can be stepped through and individual components (motor, heater, valves on gas models) actuated.

  4. 4

    Without entering diagnostics, the two highest-value checks are: thermal fuse continuity (back panel, on the blower housing) and thermistor resistance (~10kΩ at room temp).

💡 Good to know: The AF (airflow) code is a measurement of duct restriction — treat it as a maintenance instruction, not a part failure.

Frequently Asked Questions

Why won't my Whirlpool dryer heat even after resetting? +
A blown thermal fuse or cutoff doesn't reset — it must be replaced. They blow protectively when the vent is restricted, so clean the full duct run or the replacement will fail too.
