The E3 error in Lloyd AC indicates an Indoor Coil Temperature Sensor Fault. This error occurs when the sensor responsible for monitoring the temperature of the indoor evaporator coil malfunctions or fails to send accurate readings. The indoor coil temperature sensor is crucial for regulating the cooling or heating process, as it helps the system determine if the coil is operating within the correct temperature range. When the E3 error is triggered, it usually means the sensor is either damaged, disconnected, or providing incorrect readings. This can prevent the air conditioning system from properly controlling the evaporator coil’s temperature, leading to issues such as inadequate cooling or heating, or the system may stop functioning to avoid further damage. To resolve the E3 error, it is important to inspect the indoor coil temperature sensor for any visible damage or disconnections. If the sensor is found to be faulty, it will need to be replaced. Additionally, check the wiring and control board to ensure there are no issues with the connections. Once the faulty component is repaired or replaced, the system should reset, and the air conditioner will return to normal operation. Regular maintenance, including checking the indoor coil temperature sensor and ensuring proper connections, can help prevent the E3 error and maintain the efficiency of your Lloyd AC system.
