Possible Causes
Defective NTC sensor, loose NTC connector, wiring harness damage, control board misreading sensor
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing internal components.
Step-by-step:
- Access NTC: Remove rear or front lower panel to reach the NTC mounted in the tub or heater housing.
- Check connector: Reseat the NTC connector and inspect for corrosion or moisture.
- Measure resistance: At room temperature, verify the NTC resistance matches Whirlpool specs. Resistance should change smoothly with temperature.
- Inspect wiring: Trace the harness from NTC to control for pinched or broken wires.
- Replace NTC: If readings are erratic or out of range, install a new Whirlpool NTC sensor.
When to call a technician: If the NTC and wiring are good but F24 persists, the control board may be faulty and should be evaluated by a professional.
