KitchenAid Dryer Error Code F22 — Outlet Thermistor Failure
What this means
The F22 error code on KitchenAid dryers indicates the outlet thermistor (exhaust temperature sensor) has failed. This sensor measures the temperature of air leaving the dryer drum. When it fails, the dryer cannot accurately control the drying temperature, which may result in clothes not drying properly or the dryer shutting off prematurely.
Step-by-step fix
4 stepsReset the dryer
Unplug for 30 seconds, plug back in. If the code clears, it was a temporary fault.
Locate the outlet thermistor
The outlet thermistor is near the exhaust duct or blower housing. Access it by removing the rear panel or lint duct area.
Test the thermistor
Disconnect the thermistor wires and test with a multimeter. At room temperature, it should read approximately 10,000 ohms (10K). A reading of 0 or infinity means it's failed.
Replace the thermistor
If faulty, replace the outlet thermistor. It's typically mounted with one or two screws.
When to call a professional
If the thermistor tests good but the code persists, the control board's temperature input may be faulty.
