How to fix it
- Unplug the dryer and access the heater assembly (typically requires removing the back panel on electric models or the front/toe panel on gas).
- Locate the inlet thermistor near the heater inlet.
- Measure resistance and compare against the tech sheet (around 10 kΩ at 77°F).
- Replace if out of spec or open.
- Inspect and clean the lint screen housing and vent — overheat events are usually airflow related.
- Reassemble and run a heated cycle to verify the fault clears.
