The F3 error in Lloyd AC indicates an IPM fault (Intelligent Power Module fault). The IPM is a critical component in the air conditioning system that helps regulate and control the power supply to the compressor and other major components. It ensures that the system operates efficiently by managing the electrical current, voltage, and protection mechanisms for the compressor motor and other key parts. When the F3 error occurs, it suggests that there is a malfunction or failure in the IPM, which could be caused by electrical issues such as voltage surges, overheating, or internal component failure. A faulty IPM can disrupt the AC’s operation by affecting the power management system, leading to improper functioning of the compressor or even a complete shutdown of the system to prevent further damage. To resolve the F3 error, the faulty IPM needs to be inspected and either repaired or replaced. In some cases, the issue may be related to the power supply or other electrical components, so a full diagnostic check is required to pinpoint the exact cause. Regular maintenance and protection from electrical surges can help prevent IPM faults and ensure the air conditioner continues to function properly.
