L4 Error In Voltas

The L4 error in Voltas AC signals a Phase Current Sampling Abnormality. This error occurs when the system detects an issue with the phase current sampling process, which is crucial for monitoring the electrical current flow in each phase of the air conditioner's power supply. The phase current sampling ensures the correct distribution of power to key components like the compressor and fan, allowing the air conditioner to operate efficiently. When the L4 error is triggered, it typically points to a malfunction or irregularity in the phase current sampling mechanism. This could be caused by damaged sensors, faulty wiring, or problems within the control board. An abnormal phase current sampling can lead to an unbalanced power supply, which may cause operational inefficiencies or even damage to the unit. To resolve the L4 error, it's essential to inspect the phase current sensors and associated wiring for any visible damage or loose connections. If any issues are found, repairing or replacing the faulty components will likely resolve the error. Additionally, the control board should be checked for any faults that may be affecting the current sampling process. Once the L4 error is addressed and the faulty components are replaced, the air conditioner should return to normal operation. Regular maintenance, such as checking the sensors, wiring, and control board, can help prevent future occurrences of the L4 error and ensure your Voltas AC runs smoothly and efficiently.
