Indoor unit displays E2 and stops cooling; fan may still run
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Turn off the unit and isolate power before opening the indoor cover.
- Clean or replace air filters: Open the front panel of the SMEG indoor unit, remove the mesh filters, and wash them with mild detergent and water. Let them dry completely before reinstalling.
- Inspect evaporator coil: With filters removed, visually check the aluminum fins. If heavily dusted or iced, allow ice to melt (leave unit off for several hours) and then gently clean with a soft brush or coil cleaner.
- Check indoor fan operation: Turn the unit back on and verify the indoor fan runs at all speed settings. If the fan is slow, noisy, or fails to start, the indoor fan motor or capacitor may be failing.
- Verify room airflow: Ensure no furniture or curtains block the air inlet or outlet of the indoor unit.
If E2 recurs after cleaning and airflow checks, the system may have low refrigerant or a sensor issue; contact a technician for pressure and leak testing.
