Climatrol air conditioners have been effective in cooling my home during hot summers. Fortunately, I’ve had relatively few issues with these units. On one occasion, the air conditioner stopped working, and I promptly contacted customer service. The technician arrived within a reasonable timeframe and resolved the issue. However, better communication regarding the technician’s arrival time would have been appreciated.
E01: Evaporator Temperature Sensor Fault
The sensor monitoring the evaporator coil’s temperature is malfunctioning or out of range.
E02: Condenser Temperature Sensor Fault
The sensor monitoring the condenser coil’s temperature is not working correctly.
E03: Low Refrigerant Level
The system has detected a low level of refrigerant, which might affect cooling efficiency.
E04: Compressor Overload
The compressor is overloaded, which might be due to a malfunction or external factors.
E05: Fan Motor Fault
There’s an issue with the air conditioner’s fan motor.
E06: Drainage Error
Water is not draining properly from the unit, which can lead to leaks.
E07: Electrical Issue
An electrical issue, such as a short circuit or a blown fuse, has been detected.
E08: Communication Error
The internal systems or components are not communicating properly.
E09: High Pressure Alert
The system is detecting unusually high pressure, which can be a safety concern.
E10: Filter Replacement Reminder
The filter needs to be checked or replaced to maintain optimal air quality and efficiency.
E11: Coil Frost Over
The evaporator coil is frosting over, which can impair the unit’s efficiency and cooling capability.
E12: Overcurrent Error
The system has detected an overcurrent situation, potentially due to a malfunctioning component or electrical issue.
E13: Ambient Temperature Sensor Fault
The sensor that measures the room’s ambient temperature is malfunctioning or sending inconsistent readings.
E14: Defrosting Issue
The unit’s defrosting mechanism is not working properly, which can affect performance in certain conditions.
E15: External Unit Communication Error
The internal and external units (for split systems) are having communication problems.
E16: High Humidity Warning
The system has detected high humidity levels, which may affect the unit’s efficiency.
E17: Voltage Irregularity
An inconsistency or irregularity in the power supply voltage has been identified.
E18: Remote Control Signal Error
The unit is having difficulty receiving signals from the remote control.
E19: Internal Component Overheat
An internal component, other than the compressor, is overheating.
E20: Expansion Valve Fault
The expansion valve, crucial for the refrigeration cycle, is malfunctioning.
