Blue Star AC Error Codes List
Whenever Blue Star puts a mistake code on the AC screen, consumers don’t know what these error codes mean. If consumers know what the error code means, they will help diagnose the matter in their AC. we’ve prepared an inventory of all Blue Star air conditioning error codes and what they mean for your convenience. If consumers know what problems they’re facing, they will give accurate information to the upkeep team or repair the AC unit themselves. Here is the complete list of Blue
Star air conditioning error codes.
E1: This error code indicates a high-temperature issue in the evaporator coil. It means that the coil is getting too hot, which could be caused by a lack of refrigerant, a clogged air filter that restricts airflow, or a problem with the fan motor that fails to circulate air properly.
E2: An E2 error code typically points to a fault with the indoor temperature sensor. The sensor may be malfunctioning, providing inaccurate temperature readings, or there could be a problem with its wiring.
E3: This code usually indicates a problem with the outdoor temperature sensor. It means that there may be an issue with the sensor itself, such as damage or disconnection, or there could be a problem with the wiring that connects the sensor to the AC unit.
E4: An E4 error code typically suggests a communication error between the indoor and outdoor units of the AC. This can be caused by faulty wiring connections, loose connections, or a malfunctioning control board that is responsible for communication between the units.
E5: This error code generally points to a problem with the fan motor or fan speed control. It could indicate a faulty motor that is not functioning properly or issues with the control board responsible for regulating the fan speed.
E6: An E6 error code indicates a fault with the indoor unit's evaporator coil temperature sensor. The sensor may be defective or there could be a problem with the wiring connection to the sensor.
E7: This code typically signifies a problem with the outdoor unit's condenser coil temperature sensor. It means that the sensor may be damaged, disconnected, or experiencing issues with its wiring.
E8: An E8 error code usually suggests a problem with the high-pressure switch. It is triggered when there is excessive pressure in the AC system, which could be caused by a malfunctioning compressor or a blockage in the refrigerant lines.
E9: This error code typically indicates a problem with the low-pressure switch. It means that the AC system may be experiencing low refrigerant levels, the switch itself may be faulty, or there could be an issue with the pressure sensor.
P0: A P0 error code generally indicates a fault in the power supply or voltage. It could be due to problems with the electrical connection, power fluctuations, or a malfunctioning control board responsible for managing power-related functions.
It's important to note that the specific meanings of error codes may vary slightly depending on the model and series of Blue Star inverter AC you own. It's recommended to refer to the user manual or contact Blue Star customer support for precise information related to your AC model and its error codes.
