E4 Error In Carrier

Added on: November 16, 2024

The E4 error in Carrier AC indicates an issue with the indoor air temperature sensor, meaning that the sensor responsible for measuring the temperature of the air inside the room is malfunctioning or providing incorrect readings. This sensor plays a key role in regulating the air conditioner's cooling cycle, ensuring that the system adjusts its operation to maintain the desired indoor temperature. When the E4 error occurs, it typically suggests that the indoor air temperature sensor is faulty, disconnected, or reading abnormal temperatures. This could be caused by a sensor malfunction, wiring issues, or a problem with the sensor's connection to the control board. If the sensor is not functioning correctly, the air conditioner may struggle to maintain the set temperature, leading to inefficient cooling or erratic operation. To protect the system, the E4 error disables the air conditioner's cooling function until the issue with the sensor is resolved. Once the faulty sensor is replaced or the wiring is repaired, the system will reset, and the air conditioner will return to normal operation. Regular maintenance, including checking the indoor air temperature sensor and ensuring proper wiring and connections, can help prevent the E4 error and ensure that the Carrier AC operates efficiently and effectively.
