How to Fix / Troubleshooting
Safety: Unplug the unit before inspection.
- Check ambient temperature: If the room is below about 10°C, the unit may struggle and trigger defrost-related errors. Move it to a warmer room.
- Inspect evaporator: If you can access the evaporator coil, check for heavy ice buildup. Allow the unit to thaw completely before restarting.
- Sensor attachment: Ensure the defrost sensor is clipped firmly to the evaporator tubing and not hanging loose.
- Clean airflow path: Clean the air filter and ensure nothing blocks the intake or outlet.
- Persistent E6: The defrost sensor or control PCB may need replacement. This is best handled by a service technician.
