Lloyd, a brand under Havells, is known for producing efficient and reliable air conditioners. Like most modern appliances, Lloyd Window AC units come with a self-diagnosis feature that displays error codes on the digital panel when something goes wrong.

Knowing what these error codes mean can save time and money — helping you fix minor issues yourself or knowing when to call a technician.

Below is a list of common Lloyd Window AC error codes, along with a brief description and solution for each one.

✅ Lloyd Window AC Error Code List with Description & Solutions

E1 – Indoor Room Temperature Sensor Error

• Description: The sensor that reads room temperature is disconnected, damaged, or malfunctioning.
• Solution:
  • Restart the AC to reset the system.
  • Inspect the sensor and its wiring for damage.
  • Replace the sensor if the issue persists.

E2 – Evaporator Coil Sensor Error

• Description: The evaporator coil (indoor unit) sensor is not detecting temperature correctly.
• Solution:
  • Clean the coils to eliminate sensor reading errors.
  • Ensure sensor wiring is connected properly.
  • Replace the sensor if needed.

E3 – Indoor Fan Motor Error

• Description: The fan motor is running irregularly or not at all.
• Solution:
  • Clean fan blades and remove obstructions.
  • Check fan motor capacitor and replace if faulty.
  • If the motor is damaged, replace it.

E4 – Overload or High Compressor Discharge Temperature

• Description: Compressor is overheating, often due to poor ventilation or high ambient temperature.
• Solution:
  • Turn off the AC and let it cool down for 15–30 minutes.
  • Clean air filters and ensure good airflow.
  • If the error repeats, call a technician to check refrigerant levels and compressor health.

E5 – Communication Error

• Description: Fault in communication between indoor unit and control PCB.
• Solution:
  • Power off the AC and restart it after a few minutes.
  • Check internal wiring for disconnections or damage.
  • PCB might require servicing or replacement if problem continues.

E6 – Voltage Fluctuation or Overcurrent Error

• Description: The system detects abnormal voltage or high current flow, which could damage the unit.
• Solution:
  • Use a stabilizer suitable for your AC’s tonnage.
  • Avoid running the AC on generator/inverter power unless compatible.
  • Contact a technician to test the power supply and compressor.

F1 – EEPROM or Control Board Memory Error

• Description: The electronic control board cannot retrieve or process saved settings properly.
• Solution:
  • Restart the AC to attempt memory reset.
  • If issue continues, the control board might need replacement by a service engineer.

🔧 General Tips to Prevent Lloyd AC Errors

• 🧽 Clean filters every 2–3 weeks to avoid airflow and sensor issues.
• ⚡ Use a stabilizer to protect your AC from voltage fluctuations.
• 💧 Check drainage outlets regularly to avoid overflow or blockages.
• 🔍 Schedule bi-annual servicing from authorized Lloyd technicians.
• 🌬️ Keep the AC installed in a well-ventilated location for proper heat dissipation.

📞 When to Call a Technician

You should call a Lloyd-certified technician if:

• The same error code keeps showing after restart.
• The unit is not cooling properly.
• You notice unusual sounds, water leakage, or burning smells.
• You’re not confident handling internal components.

🏁 Conclusion

Understanding the Lloyd Window AC error code list can help you quickly identify problems and take the right action. While some issues like dirty filters or sensor placement are easy to fix yourself, deeper problems involving PCBs, fan motors, or compressors should be addressed by professionals.
