During a heatwave, my Daewoo air conditioner unexpectedly stopped cooling. The service process proved to be somewhat frustrating. It took several days to secure a technician visit, and the initial diagnosis did not accurately pinpoint the issue. This led to multiple service visits and an extended period without cooling.
E01: Temperature Sensor Fault
The air conditioner’s temperature sensor is malfunctioning, leading to incorrect temperature readings and cooling inefficiencies.
E02: Fan Motor Error
There’s an issue with the fan motor, which affects air circulation and can result in inadequate cooling or heating.
E03: Refrigerant Leak Detected
The air conditioner’s sensors have detected a potential refrigerant leak, which can lead to reduced cooling or heating capacity.
E04: Compressor Overload
The compressor is overloaded or overheating, possibly due to blockages, low refrigerant levels, or electrical problems.
E05: Condenser Coil Issue
There’s a problem with the condenser coil, affecting heat dissipation and overall cooling efficiency.
E06: Evaporator Coil Error
The evaporator coil is malfunctioning, potentially causing freezing or inadequate cooling.
E07: Water Leakage Detected
The air conditioner has detected water leakage, which can lead to damage and potential electrical hazards.
E08: Control Board Communication Error
There’s a communication issue between the control board and other components of the air conditioner.
E09: Air Filter Alert
The air conditioner indicates that it’s time to clean or replace the air filter for optimal performance and air quality.
E10: Remote Control Signal Loss
The air conditioner is not receiving signals from the remote control, affecting user interactions and settings.
E11: Airflow Obstruction
The air conditioner has detected an obstruction in the airflow path, possibly due to a blocked vent or duct.
E12: Low Refrigerant Pressure
The air conditioner’s sensors indicate low refrigerant pressure, which can lead to reduced cooling or heating capacity.
E13: Voltage Fluctuation
The air conditioner detects irregularities in the power supply voltage, which can impact its operation and performance.
E14: Louver Motor Error
There’s an issue with the motor controlling the direction of the air louvers, affecting air distribution.
E15: Condensate Drain Blockage
The condensate drain is blocked, leading to water accumulation within the air conditioner, which can cause damage or leaks.
E16: Remote Control Battery Low
The remote control’s batteries are running low, affecting the ability to communicate with the air conditioner.
E17: Inconsistent Temperature Output
The air conditioner is not maintaining a consistent temperature output, potentially due to control board or sensor malfunctions.
E18: Mode Selection Error
There’s an issue with the mode selection, preventing the air conditioner from switching between cooling, heating, and fan modes.
E19: Excessive Dust Buildup
The air conditioner’s internal components are coated with excessive dust, affecting its efficiency and air quality.
E20: System Shutdown
The air conditioner has encountered a severe issue and has shut down to prevent further damage. Professional servicing may be required.
