Kenmore Dryer F22 error code
The exhaust thermistor circuit is open. The dryer cannot read the exhaust air temperature, so it shuts off instead of heating blindly.
Also shown as: F22, F 22, F-22
Last updated: October 6, 2026
What causes the F22 error?
- Open or failed exhaust (outlet) thermistor
- Loose or disconnected thermistor wiring
- Damaged wire harness between the thermistor and the control
- Failed main control board reading the sensor
How to fix Kenmore F22 — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Power-reset the dryer
Unplug the dryer for 5 minutes, then plug it back in and try a cycle. If F22 returns, the sensor circuit has a real fault. - Clean the lint screen and vent
A clean lint screen and a clear vent keep heat moving normally. Pull out lint buildup and check that the outside vent flap opens freely. Poor airflow stresses the heat sensors. - Check the thermistor wiring
Unplug the dryer and locate the exhaust thermistor near the blower housing. Push its wire connector on firmly and look for broken or pinched wires. A technician can test the thermistor, which should read about 10,000 ohms at room temperature.Safety warning: Unplug the dryer before touching any internal wiring or sensor.
When to call a technician
- F22 returns after a reset with clean lint and vent
- The thermistor tests open or far from about 10k ohms
- Wiring between the thermistor and the control is damaged
- The main control board needs replacement
Frequently asked questions
What does F22 mean on a Kenmore dryer?
It means the exhaust thermistor, the sensor that measures hot air leaving the drum, has an open circuit. The dryer shuts off because it cannot control the heat safely.
Can I run the dryer on air dry with F22?
Some owners find air-dry runs without tripping the code, since no heat is involved. That only confirms the heat sensor circuit is the problem; it does not fix it.
Is F22 the same as washer F22?
No. Dryer F22 is an exhaust temperature sensor fault. Washer F22 is a door lock fault. Same number, completely different meaning.
