What Does Error F23 Mean?

The Whirlpool dryer error F23 signals a malfunctioning thermistor, which is responsible for regulating the temperature. This can lead to inadequate heating or erratic temperature readings. Common symptoms include the dryer stopping and displaying the F23 code during operation. Diagnosing the issue typically involves checking the outlet/exhaust thermistor for shorts or low resistance, as well as inspecting wiring and the control board.

Common Symptoms:

  • Dryer stops and displays F23 code upon start or during cycle
  • Dryer may not heat properly
  • Error persists even after basic resets

Possible Causes

  • Outlet/exhaust thermistor failure (shorted or low resistance) (high)
  • Loose or damaged wiring/connectors at thermistor or control board (medium)
  • Control board not responding correctly to thermistor input (medium)

How to Fix Error F23

DIY Fix Basic reset and airflow check

  1. Disconnect the dryer from power (unplug or turn off circuit breaker) for ~5 minutes.
  2. Restore power and run a time dry cycle to see if the F23 reappears.
  3. Clean the lint filter and check exterior vent for blockages to ensure proper airflow.

Technician Only Thermistor and wiring diagnostics/replacement

  1. Disconnect power and access the dryer’s exhaust or blower housing area.
  2. Locate the outlet/exhaust thermistor and inspect for visible damage.
  3. Measure thermistor resistance with a multimeter; compare with expected range.
  4. Inspect associated wiring and connectors for damage or looseness.
  5. Replace the thermistor if out of spec; repair or replace wiring as needed.
  6. Test dryer operation and confirm F23 code no longer appears.

Parts needed: Outlet/exhaust thermistor, Wiring harness/connectors (if damaged)

Technician Only Control board evaluation/replacement

  1. If thermistor and wiring check OK but F23 persists, test control board outputs and sensor inputs.
  2. Replace the main control board if confirmed to be failing to process thermistor data correctly.

Parts needed: Main control board

🛑 When to Call a Pro:
  • If error persists after basic reset and cleaning
  • If you are uncomfortable performing electrical diagnostics
  • If thermistor and wiring appear intact but code remains
