Possible Causes
Out-of-range humidity sensor, Sensor contamination, Loose sensor connector, Faulty main PCB ADC circuit
How to Fix / Troubleshooting
Safety: Unplug the unit before opening the control panel.
- Reset and test: Power cycle the unit and compare the displayed humidity to a separate hygrometer. If readings are wildly inaccurate or F0 appears, continue.
- Clean sensor area: Remove the front grille and gently clean dust from the humidity sensor area with compressed air.
- Check sensor connection: Access the control panel and ensure the humidity sensor plug is firmly connected to the main PCB.
- Replace humidity sensor: If F0 persists, replace the humidity sensor module with a TCL-compatible part.
- Control board replacement: If a new sensor does not resolve F0, the main PCB’s analog-to-digital converter may be faulty and the board will need replacement.
