How to Fix Blue Star 1.5 Ton AC E6 Error Code
The E6 error code on a Blue Star 1.5 ton air conditioner typically indicates a communication failure between the indoor and outdoor units. This often occurs due to loose wiring connections, power fluctuations, or a faulty PCB signal.
Step-by-Step Reset Procedure
- Turn off the AC using the remote control and then switch off the main power supply from the wall socket.
- Unplug the power cord from the wall outlet completely to ensure no residual charge remains.
- Wait for at least 10 to 15 minutes to allow the internal capacitors to discharge fully.
- Plug the unit back in and switch on the main power supply.
- Turn the AC on using the remote and wait for 5 minutes to see if the E6 error code clears.
Safe Steps to Try Before Calling a Technician
- Inspect the outdoor unit for any visible damage to the communication cables connecting the indoor and outdoor units.
- Ensure that the voltage stabilizer (if used) is providing a steady output, as power fluctuations can trigger communication errors.
- Check if any pests or rodents have damaged the wiring near the outdoor unit terminal block.
- Clean the air filters, as restricted airflow can sometimes cause the system to trigger protective error codes.
Always switch off the main power supply before inspecting any cables. Do not attempt to open the PCB panel or touch internal electrical components if you are not trained, as this poses a severe risk of electric shock.

Frequently Asked Questions
What does the E6 error code mean on my Blue Star AC?
The E6 error code signifies a communication fault, meaning the indoor unit and the outdoor unit are unable to send or receive signals properly.
Can I fix the E6 error myself?
You can attempt a power reset as described above. However, if the error persists, it usually indicates a faulty PCB or a damaged communication wire, which requires a professional technician.
Is the E6 error dangerous for my AC?
While the error itself is a safety feature to prevent further damage, running the AC while it is in an error state is not recommended as it may lead to compressor failure.
How long should I wait after a power cut before turning on my AC?
It is recommended to wait at least 5 minutes after power is restored to ensure voltage stability, which helps prevent communication errors like E6.
