How to Fix / Troubleshooting
Danger: High refrigerant pressure is hazardous. Do not tamper with refrigerant lines.
- Clean outdoor coil: Turn off power and clean the outdoor coil fins of the Olimpia Splendid unit with a soft brush. Remove leaves and debris.
- Check outdoor fan: Ensure the outdoor fan starts and runs at full speed. See fan motor fault entries if it does not.
- Verify airflow clearance: Maintain adequate space around the outdoor unit for proper heat rejection.
