Haier air conditioners offer cooling and heating solutions for indoor spaces. Whether it’s a window unit, split system, or portable unit, these appliances provide efficient climate control. They are designed for energy efficiency, quiet operation, and precise temperature adjustment, ensuring your home remains comfortable year-round.
E01: Filter Detection Fault
The air conditioner can’t detect if the filter is in place or properly seated. Ensure the filter is clean, properly positioned, and free from obstructions.
E02: Evaporator Temperature Sensor Error
The evaporator temperature sensor is producing inconsistent readings. Check the sensor for damage or misplacement and verify its connections.
E03: Condenser Temperature Sensor Error
The condenser temperature sensor is malfunctioning or returning readings outside the expected range. Inspect the sensor and its connections for any anomalies.
E04: Compressor Overload
The compressor is overheating or working harder than normal. Ensure the surrounding area is free from obstructions and that the unit has adequate ventilation.
E05: Fan Motor Fault
The fan motor, responsible for circulating air, is malfunctioning. Ensure it is free from obstructions and check its electrical connections.
E06: Refrigerant Leak Detected
The air conditioner has detected a potential refrigerant leak, which can affect cooling efficiency and is environmentally hazardous. Consult a professional technician to inspect and address the issue.
E07: Drainage Fault
Water produced from condensation is not draining properly. Check the drainage hose or pan for blockages and ensure it’s positioned correctly.
E08: Remote Communication Error
The air conditioner is having difficulty communicating with the remote control. Ensure the remote’s batteries are fresh, and that the IR sensor on the unit is clean and unobstructed.
E09: Coil Frost Detection
Frost or ice has been detected on the evaporator coil, affecting the cooling efficiency. This could be due to low refrigerant levels or inadequate airflow. Ensure filters are clean and the air flow is not restricted.
E10: Voltage Fluctuation Detected
The air conditioner has detected inconsistent voltage, which can affect its performance and longevity. It’s advised to use a stabilizer or check the household electrical system.
E11: Internal Memory Error
The internal memory of the air conditioner is malfunctioning, leading to potential operation issues. A reset might be necessary, and if the issue persists, consulting a technician is recommended.
E12: Humidity Sensor Fault
The humidity sensor, responsible for detecting room humidity levels, is malfunctioning. Ensure the sensor is free from obstructions and verify its connections.
E13: Overcurrent Protection
The air conditioner is drawing more current than expected. This can be a sign of an internal malfunction. Turn off the unit and seek professional inspection.
E14: Low Refrigerant Warning
The air conditioner’s refrigerant level is lower than optimal, which can affect cooling efficiency. A recharge or leak inspection might be necessary.
