How to Fix / Troubleshooting
Safety: Unplug before removing covers.
Steps:
- Check room temperature: Ensure the room is above the minimum specified (typically 5°C). Move the unit to a warmer area if needed.
- Inspect ambient sensor: Verify the ambient NTC sensor is correctly positioned near the air inlet and not touching hot components.
- Test sensor: Measure resistance and compare to expected values. Replace if open/shorted.
- Reset unit: After moving to a suitable environment and checking the sensor, unplug for 10 minutes and restart.
- PCB issue: Persistent F2 with a good sensor and proper temperature suggests a PCB fault requiring replacement.
