Possible Causes
Refrigerant leak in evaporator or condenser, Blocked capillary tube or expansion device, Severely dirty coils causing incorrect temperature readings, Faulty evaporator sensor misinterpreting system state
How to Fix / Troubleshooting
Safety: Do not attempt to open the sealed refrigeration circuit. Only certified refrigeration technicians may handle refrigerant.
- Clean coils and filter: Remove and clean the air filter. Brush and vacuum both evaporator and condenser coils to ensure good heat exchange.
- Check for icing: Run the unit and inspect the evaporator. If only a small section ices up or there is uneven frost, this can indicate low refrigerant.
- Listen for compressor: Confirm that the compressor is running (low humming sound) when F0 appears. If not, see compressor-related entries.
- Sensor check: Verify that the evaporator NTC sensor is properly attached and functioning; a bad sensor can falsely trigger F0.
- Professional leak test: If cleaning and sensor checks do not resolve F0, contact an authorized AEG service center to perform a leak test, repair any leaks, and recharge the system.
