How to Fix / Troubleshooting
Warning: The compressor and pipes can be extremely hot. Allow the unit to cool before touching.
- Turn off and cool: Switch off the Olimpia Splendid unit and let it cool for at least 30 minutes.
- Clean filters and coils: Ensure all filters are clean and both indoor and outdoor coils are free of dirt.
- Check fan operation: Confirm that both fans run correctly. Repair any fan issues first.
- Restart and monitor: After cleaning, restart and observe. If H3 returns quickly, a deeper refrigerant or compressor issue is likely.
- Professional service: A technician should check refrigerant charge, compressor current draw, and the thermal protector.
