How to Fix / Troubleshooting
Safety first: Turn off power. Compressor and electrical components can be hazardous.
- Allow cooling: Let the unit sit powered off for at least 30 minutes to allow the compressor to cool and the overload to reset.
- Check airflow: Ensure the outdoor coil is clean and the fan is operating correctly.
- Verify supply voltage: Have a qualified person measure voltage at the unit while running to ensure it is within AstralPool specifications.
If E05 recurs frequently, the compressor or overload device may be failing and should be evaluated by a refrigeration technician.
