Possible Causes
Low refrigerant charge due to micro-leak in evaporator or condenser, Blocked capillary tube or filter-drier, Severely iced evaporator causing sensor misread, Faulty evaporator temperature sensor misinterpreted as low refrigerant
How to Fix / Troubleshooting
Safety first: Unplug the unit. The sealed system is under pressure and contains refrigerant; only certified technicians should open it.
- Visual inspection of coils: Remove covers to inspect the evaporator and condenser coils. Look for oily residue, which can indicate a refrigerant leak.
- Check for frost pattern: Run the unit for 10–15 minutes and observe the evaporator. If only a small section ices or remains warm, refrigerant may be low.
- Clean coils and filter: Ensure both coils and the air filter are clean to rule out airflow issues that can mimic low refrigerant symptoms.
- Verify sensors: Confirm the evaporator temperature sensor is properly attached and functioning. A bad sensor can trigger EC erroneously.
- Professional service: If EC persists and signs point to a sealed system issue, contact an authorized Electrolux service center.
