How to Fix / Troubleshooting
Safety first: Disconnect power and allow time for water and heater to cool.
Step-by-step checks:
- Locate and test NTC: Find the NTC sensor near the heater in the tub. Disconnect and measure resistance at room temperature. Compare to Whirlpool specifications.
- Inspect connector: Look for corrosion or loose pins at the NTC and control board ends. Clean and reseat.
When to replace: Replace the NTC if readings are out of range or intermittent. If the sensor and wiring are good but F23 persists, the main control board may be defective.
