Failed indoor ambient NTC sensor, Loose sensor connector on indoor PCB, Damaged sensor cable, Faulty PCB sensor circuit
How to Fix / Troubleshooting
Safety: Disconnect power before removing the front cover.
- Access sensor: Remove the front panel and filter of the Olimpia Splendid indoor unit. The ambient sensor is often near the air intake grille.
- Inspect sensor and wiring: Ensure the sensor is not broken or hanging loose. Check the cable for cuts or pinches.
- Reseat connector: Follow the cable to the PCB and unplug/replug the connector to ensure good contact.
- Test resistance: Use a multimeter to measure sensor resistance at room temperature. Replace the sensor if readings are open, shorted, or far from expected values.
- PCB check: If a new sensor does not clear F1, the indoor PCB may be defective and require replacement.
