Possible Causes
Failed RH sensor module, Moisture ingress into sensor, Loose sensor connector, Faulty control board input
How to Fix / Troubleshooting
Safety: Disconnect power before accessing the control panel.
Steps:
- Locate RH sensor: Typically mounted near the air outlet or intake, often on a small PCB with vent holes.
- Inspect for condensation: If the sensor is wet, allow it to dry completely. Avoid direct water contact in future cleaning.
- Check cable and connector: Ensure the sensor harness is intact and firmly plugged into the main PCB.
- Replace sensor: If F2 persists, replace the humidity sensor module with the correct Trotec part.
- Control board: Persistent F2 with a new sensor suggests a faulty main PCB.
