How to Fix / Troubleshooting
Safety first: Unplug the appliance.
- Check sensor connection: Access the NTC at the heater bracket and ensure the connector is fully seated.
- Inspect wiring: Look for broken wires or loose connections between the sensor and control board. Repair as needed.
- Test NTC: Measure resistance at room temperature. If the meter shows OL (open), replace the sensor.
- Replace sensor or control: Install a new KitchenAid NTC if faulty. If wiring and sensor are good but F38 persists, the main control may need replacement.
