The L3 error in Voltas AC indicates a Drive Phase Current Overload Protection issue. This error occurs when the system detects an overload in the drive phase current, which is crucial for the proper operation of the air conditioner’s compressor and other motor-driven components. The drive phase current is monitored to ensure that the system operates within safe electrical limits, preventing damage to the compressor or other vital parts. When the L3 error is triggered, it typically means that one of the phases in the system is drawing more current than normal, causing the system to activate the overload protection. This can happen due to issues like worn-out motor components, faulty wiring, imbalanced power supply, or problems with the control board. To resolve the L3 error, it is important to check the drive phase current for any signs of imbalance or overload. Inspect the motor, wiring, and connections to identify any faults that may be causing excessive current flow. If the compressor, motor, or wiring is damaged, repairs or replacements may be necessary. Once the issue is addressed, and the faulty components are repaired or replaced, the system should reset, and normal operation will resume. Regular maintenance, including monitoring the drive phase current and ensuring all electrical components are functioning correctly, can help prevent future L3 errors and maintain the efficiency of your Voltas AC system.
