KitchenAid Dryer Error Code F23 — Outlet Thermistor Open/Short
What this means
The F23 error code on KitchenAid dryers indicates the outlet thermistor has an open or short circuit. Similar to F22, this affects the exhaust temperature measurement, but F23 specifically indicates a more definitive circuit failure — either a break (open) or a direct short in the sensor or its wiring.
Step-by-step fix
3 stepsTest the outlet thermistor
Unplug the dryer. Access the outlet thermistor near the exhaust area. Disconnect and test with a multimeter. At room temperature, expect approximately 10,000 ohms. Zero (short) or infinity (open) means it's failed.
Check the wiring
Inspect wires between the thermistor and control board for breaks, pinched insulation, or loose connectors.
Replace the thermistor
Replace the outlet thermistor if it tests open or shorted.
When to call a professional
If the sensor and wiring are good but the code persists, the control board may need replacement.
