What this code means
On models with a vent sensor or second thermistor, this code indicates restricted airflow or an abnormal secondary temperature-sensor reading.
Most likely causes
- The lint screen or exhaust duct is clogged
- The transition duct is crushed behind the dryer
- The secondary thermistor or vent sensor is out of range
- A harness or control input has failed
Safe checks for the owner
- Clean the lint screen and inspect the entire vent run to the outside.
- Confirm that the exterior hood opens freely and is not blocked by lint, snow or a screen.
- Stop using the dryer if drying times are long or the cabinet becomes unusually hot.
Estimated U.S. repair cost
$190–$390, depending on model, access, parts availability and local labor.
