Possible Causes
Open or shorted NTC sensor, failed heating element, wiring fault between heater/NTC and control, control board sensing circuit failure
How to Fix / Troubleshooting
Safety First: Disconnect power and allow the unit to cool before testing heater components.
Step-by-step checks:
- Test NTC: Remove the rear panel and locate the temperature sensor. Measure its resistance at room temperature and compare to spec. Check for smooth resistance change with temperature.
- Test heater: Measure heater resistance and check for shorts to ground as in F07.
- Inspect harness: Verify all connectors are tight and wires are not damaged.
When to replace: Replace any defective NTC or heater. If both are good and wiring is intact, replace the main control board.
