The E4 error in Lloyd AC indicates an Indoor Ambient Temperature Sensor Fault. This error occurs when the indoor ambient temperature sensor, responsible for detecting the temperature inside the room, malfunctions or fails to provide accurate readings. The sensor plays a crucial role in the air conditioning system by ensuring that the unit adjusts its cooling or heating output based on the current indoor temperature. If the E4 error is triggered, it typically means that the sensor is either damaged, disconnected, or providing faulty readings. As a result, the air conditioner may be unable to regulate the room temperature correctly, leading to inefficient cooling or heating, or the system may stop working altogether. To resolve the E4 error, it is important to first inspect the sensor for any visible damage or loose connections. If the sensor is found to be faulty, it should be replaced with a new one. In some cases, the issue may lie in the wiring or the control board, so these should also be checked for any faults or damage. Once the faulty component is repaired or replaced, the system should reset, and the air conditioner will resume normal operation. Regular maintenance, including inspecting the temperature sensor and wiring connections, can help prevent the E4 error and ensure the continued efficiency of your Lloyd AC system.
