Voltas Non-Inverter AC Error Code List
Here are some common error codes for Voltas non-inverter air conditioners:
E1: High-pressure protection error. This error occurs when the high-pressure switch detects abnormally high pressure in the refrigerant system.
E2: Indoor temperature sensor error. This error indicates a problem with the indoor temperature sensor, which may require replacement or recalibration.
E3: Indoor coil temperature sensor error. This error signifies a fault with the indoor coil temperature sensor, which may need to be checked or replaced.
E4: Outdoor temperature sensor error. This error suggests an issue with the outdoor temperature sensor, which may require inspection or replacement.
E5: Compressor overcurrent protection error. This error occurs when the compressor draws excessive current, indicating a potential problem with the compressor or its electrical components.
E6: Communication error between indoor and outdoor units. This error indicates a communication problem between the indoor and outdoor units, often due to wiring or control board issues.
