F24 — Temperature Thermistor Out of Range
F24 indicates the dryer temperature thermistor (temperature sensor) is reading out of range (open or shorted). It is NOT the moisture sensor — the moisture-sensor "two metal strips in the drum" faults are F28/F29 on this platform. Test the thermistor resistance and wiring.

How to fix it
- Open the door and locate the two metal strips inside the drum opening.
- Clean both strips with rubbing alcohol and a soft cloth.
- Run a sensor cycle to see if F24 clears.
- If still failing, unplug and access the front bulkhead to inspect the sensor wires.
- Reseat the moisture sensor connector.
- Replace the moisture sensor if continuity is open.
