What Does Error F3 Mean?

The Asko dryer error F3 indicates a malfunction in the temperature sensor, commonly known as the thermistor. This can lead to improper heating, erratic temperature readings, and may cause the dryer to stop mid-cycle or run indefinitely. The issue is typically due to a thermistor failure or damaged wiring between the thermistor and the control board. Regular maintenance and checks are essential to prevent airflow issues that could exacerbate the problem.

Common Symptoms:

  • Dryer may fail to reach correct drying temperature
  • Cycle stops mid‑cycle or runs indefinitely
  • Inconsistent heat behavior during operation

Possible Causes

  • Thermistor (temperature sensor) failure (medium)
  • Damaged or loose wiring between thermistor and control board (medium)

How to Fix Error F3

DIY Fix Basic checks before calling technician

  1. Unplug the dryer and allow it to cool completely.
  2. Ensure the dryer vent path and lint filters are clean (not directly fixing thermistor but eliminates airflow causes).
  3. Power the dryer back on and see if the error persists.

Technician Only Inspect and replace thermistor and wiring

  1. Disconnect power and access the internal control/temperature sensor area.
  2. Test the thermistor for continuity/resistance according to model specifications.
  3. Inspect wiring harness to thermistor for breaks, heat damage, or loose connectors.
  4. Replace the thermistor and any damaged wiring as needed.
  5. Reassemble and test dryer operation to confirm resolution.
