The P3 error in Voltas AC indicates Outdoor Unit Over-High/Over-Low AC Voltage Protection. This error occurs when the AC voltage supplied to the outdoor unit falls outside the acceptable range, either being too high or too low. The P3 error acts as a protective measure to prevent damage to the outdoor unit’s compressor and other electrical components when voltage irregularities are detected. Over-high AC voltage can result from power surges, lightning strikes, or fluctuations in the electrical grid, while over-low AC voltage can occur due to poor or unstable power supply, faulty wiring, or power outages. Both situations can cause the system to work inefficiently and may lead to severe damage to sensitive components if not addressed. To resolve the P3 error in your Voltas AC, begin by verifying the AC voltage supplied to the system. Use a voltage meter to check if the voltage is within the manufacturer’s specified range. If there are consistent voltage fluctuations, consider installing a voltage stabilizer or surge protector to protect the outdoor unit from voltage spikes or drops. Once the voltage issue is corrected, the P3 error should clear, and your Voltas AC will return to normal operation. Regularly monitoring and stabilizing your AC’s voltage supply can help prevent the P3 error and extend the lifespan of your system.
