What Does Error F04 Mean?

The Whirlpool dryer error F04 indicates a malfunction related to restricted airflow or ventilation issues. Users may experience reduced drying performance, airflow problems, or see the error displayed on the control panel. It may also occur alongside a flashing red light. Common causes include lint buildup in the exhaust vent or potential motor/tachometer sensor faults in specific models.

Common Symptoms:

  • Dryer displays "F04" on the control panel
  • Drying performance reduced or airflow issues
  • Possible red light flashing associated with the error

Possible Causes

  • Restricted airflow in the dryer exhaust/vent system (medium)
  • Model‑specific motor/tachometer sensor fault (reported in some community cases) (low)

How to Fix Error F04

DIY Fix Check and Improve Airflow

  1. Turn off and unplug the dryer.
  2. Remove and clean the lint filter thoroughly.
  3. Inspect the dryer exhaust vent and ductwork for lint buildup or obstructions.
  4. Clean the vent path (including external vent hood) to ensure free airflow.
  5. Plug the dryer back in and restart to see if the code clears.

Technician Only Inspect Internal Sensors and Components

  1. Run diagnostic mode on the dryer to confirm the F04 fault code history.
  2. Check continuity and condition of motor tachometer/rotation sensor if present for the specific model.
  3. Inspect wiring harnesses and connectors related to airflow sensors and motor sensors.
  4. Replace the motor tachometer sensor or associated components if testing indicates failure.

Parts needed: Motor tachometer/rotation sensor, Wiring harness/connector, Vent pressure/airflow sensor (if applicable)

🛑 When to Call a Pro:
  • If airflow cleaning does not resolve the error
  • If the error reappears frequently
  • If internal sensor or motor diagnostics indicate a component failure
