Insufficient refrigerant can cause the compressor to overheat. It might require a refrigerant recharge.
Faulty Compressor:
The compressor itself may be malfunctioning and need replacement.
E04: Fan Motor Error
The fan motor is not operating correctly.
Possible Causes & Solutions:
Obstructed Fan:
Ensure nothing is obstructing the fan’s movement.
Faulty Fan Motor:
The fan motor might be malfunctioning and require replacement.
Wiring Issues:
Check for any loose or damaged wiring connections to the fan motor.
E05: Drain Pan Overflow
The drain pan is overflowing or not draining properly.
Possible Causes & Solutions:
Blocked Drain Pipe:
Ensure the drain pipe is clear of any obstructions.
Improper Installation:
The unit may not be level, causing water to collect and not drain effectively.
Cracked or Damaged Drain Pan:
Inspect the drain pan for any damages and replace if necessary.
E06: Refrigerant Leak
The system has detected a potential refrigerant leak.
Possible Causes & Solutions:
Damaged Refrigerant Lines:
Inspect the lines for any visible damages or signs of refrigerant leakage.
Loose Connections:
Ensure all connections are tight and sealed properly.
Professional Inspection Needed:
Refrigerant issues should be handled by trained technicians due to environmental and safety concerns.
E07: Communication Error
The indoor unit is having communication issues with the outdoor unit.
Possible Causes & Solutions:
Faulty Wiring:
Check the communication wiring between the indoor and outdoor units for any visible damage or disconnection.
Control Board Issues:
Either the indoor or outdoor unit’s control board might be malfunctioning.
Electrical Interference:
Ensure there’s no electronic device causing interference with the system’s communication.
E08: High Pressure Alert
The system has detected excessive pressure in the refrigerant lines.
Possible Causes & Solutions:
Blocked Condenser Coil:
Ensure the outdoor condenser coil is not blocked or dirty, restricting airflow.
Faulty Expansion Valve:
The expansion valve, which regulates refrigerant flow, might be malfunctioning.
Excessive Refrigerant:
Too much refrigerant in the system can increase pressure. A technician can verify and adjust the charge.
E09: Low Pressure Alert
The system has detected insufficient pressure in the refrigerant lines.
Possible Causes & Solutions:
Refrigerant Leak:
Check for signs of a refrigerant leak in the system.
Blocked Filter:
Ensure the air filter is clean to maintain proper airflow.
Faulty Compressor:
The compressor might not be compressing the refrigerant effectively.
E10: Auto-Swing Malfunction
The auto-swing feature of the air conditioner is not working correctly.
Possible Causes & Solutions:
Obstructed Swing Flap:
Make sure there’s nothing blocking the movement of the swing flap.
Faulty Swing Motor:
The motor responsible for the auto-swing function might be malfunctioning.
Control Board Issue:
The control board might not be sending the correct signals for the auto-swing operation.
E11: Dehumidification Error
The dehumidification function is not working effectively.
Possible Causes & Solutions:
Sensor Malfunction:
The humidity sensor might be faulty and not detecting the room’s humidity correctly.
Blocked Drain:
Ensure the drain pipe is clear of any obstructions.
Refrigerant Issue:
The system might not be cooling effectively due to refrigerant problems, reducing its dehumidifying capacity.
E12: Power Supply Issue
The system is having trouble with its power supply or voltage.
Possible Causes & Solutions:
Voltage Fluctuations:
The power supply might be unstable. Ensure the unit is supplied with consistent and correct voltage.
Wiring Issue:
Check for loose or damaged wiring connections.
Circuit Breaker:
Ensure the circuit breaker for the air conditioner hasn’t tripped.
E13: Indoor Fan Speed Error
The indoor unit’s fan is not operating at the desired speed.
Possible Causes & Solutions:
Faulty Fan Motor:
The fan motor might be malfunctioning or not receiving proper power.
Blocked Air Flow:
Ensure nothing is obstructing the air intake or exhaust. Clean any dust or debris from the filters.
Control Board Malfunction:
The control board might not be sending the right signals to the fan motor.
E14: Outdoor Fan Speed Error
The outdoor unit’s fan is not operating as expected.
Possible Causes & Solutions:
Faulty Fan Motor:
The outdoor fan motor might be malfunctioning.
Obstructed Fan:
Check for any debris or obstructions that might hinder the fan’s movement.
Capacitor Issues:
The capacitor providing the initial boost to the motor might be faulty.
E15: Circuit Board Temperature High
The temperature of the main circuit board is higher than acceptable limits.
Possible Causes & Solutions:
Inadequate Ventilation:
Ensure the air conditioner, especially the indoor unit, is well-ventilated.
Faulty Components:
Components on the circuit board might be malfunctioning, generating excessive heat.
Dust Accumulation:
Dust can act as an insulator. Make sure to clean any dust from the air conditioner’s internal components.
E16: Time Setting Error
The system’s internal clock or timer is malfunctioning.
Possible Causes & Solutions:
Power Interruptions:
Frequent power outages or surges can affect the system’s internal clock.
Faulty Control Board:
The board responsible for keeping time might be malfunctioning.
Software Glitch:
Resetting the air conditioner might solve minor software issues.
E17: Remote Control Signal Error
The indoor unit is having trouble receiving signals from the remote control.
Possible Causes & Solutions:
Low Battery in Remote:
Replace the batteries in the remote control.
Distance/Obstruction:
Ensure there’s no obstruction between the remote and the indoor unit and that you’re within the effective range.
Faulty Remote:
The remote control might be malfunctioning and could need replacement.
E18: Icing Detected
Ice formation has been detected on the coils.
Possible Causes & Solutions:
Low Refrigerant Levels:
Insufficient refrigerant can cause the coils to freeze. Check for potential leaks or a need for a recharge.
Blocked Air Flow:
Ensure the filters and coils are clean and free from obstructions.
Faulty Temperature Sensors:
Sensors that don’t detect coil temperature correctly can lead to icing.
