F24 — Inlet Thermistor Fault
The inlet thermistor (near the heat source) is reading out of range — open, shorted, or drifted. Temperature control is compromised.
- Keep using it?
- Yes, with caution
- DIY difficulty
- Moderate
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.
Why it happens
Typical signs: F24 on display · No heat or weak heat · Dryer stops early · Long dry times
- Failed inlet thermistor Component drift or failure.
- Wiring fault to inlet thermistor Pinched, chafed, or loose connection.
- Damaged by overheat event Restricted airflow caused thermistor damage.
- ACU input circuit failure Rare board-level fault.
