Possible Causes
Failed compressor, Faulty inverter module, Wiring fault between compressor and control board
How to Fix / Troubleshooting
Safety first: Disconnect power. The compressor and inverter operate at high voltage; only trained personnel should work on them.
- Basic cleaning: Before assuming a compressor fault, clean all filters and the heat exchanger to ensure proper airflow.
- Listen for compressor: During a cycle (with panels in place), you should normally hear the compressor start after a few minutes. If it never starts, H02 may indicate a drive fault.
- Visual inspection: With power off, inspect the inverter module and compressor wiring for burnt marks or loose connectors.
- Professional diagnosis: Compressor and inverter faults require specialized tools and must be handled by an authorized Ariston technician.
