BLUE STAR UNIT MODEL:BVRF 21TCE ERROR CODE LIST REQUIRED

The Blue Star DX Unit E2 alarm is an error code that indicates a problem with the discharge temperature sensor. Here are some steps you can take to try and rectify the issue:

1. Turn off the DX unit and disconnect the power supply to the unit.
2. Check the wiring and connections of the discharge temperature sensor. Make sure the connections are tight and the wiring is not damaged or frayed.
3. Clean the discharge temperature sensor. Remove any dirt, dust, or debris that may have accumulated on the sensor, as this can interfere with its readings.
4. Check the sensor's resistance. Use a multimeter to check the resistance of the sensor. If the resistance is too high or too low, this may indicate a faulty sensor that needs to be replaced.
5. Replace the sensor. If the sensor is faulty, replace it with a new one that is compatible with the Blue Star DX unit.
6. Reset the unit. Once you have rectified the issue, reset the DX unit and see if the error code clears.

If you are unable to rectify the issue, or if the error code persists, it may be best to contact a qualified technician or Blue Star customer service for further assistance.

The H5 error code in a Blue Star split inverter AC typically indicates that there is a problem with the outdoor unit. The outdoor unit is the part of the air conditioning system that is located outside the building and is responsible for releasing the heat absorbed from the inside of the building to the outside.
There are a few possible causes of the H5 error code:

1. The outdoor unit's compressor might be malfunctioning. The compressor is the most important component of the outdoor unit and is responsible for compressing and circulating the refrigerant.
2. The outdoor unit's fins might be dirty or obstructed. The fins are the thin metal blades that are responsible for releasing the heat absorbed from the inside of the building to the outside. If the fins are dirty or obstructed, the heat exchange process will be impaired, resulting in the H5 error code.
3. The outdoor unit's fan motor might be malfunctioning. The fan motor is responsible for turning the fan blades that circulate the air over the fins. If the fan motor is not functioning properly, the H5 error code will be displayed.

To troubleshoot the H5 error code, you should start by checking the outdoor unit for any visible signs of damage or obstruction. If you do not see any obvious problems, you may need to call a professional HVAC technician to diagnose and repair the issue.
