Restore precise temperature sensing and efficient operation to your cooling system with the LG EBG61108909 Air Conditioner NTC Thermistor. This Negative Temperature Coefficient (NTC) sensor is a vital diagnostic component that monitors ambient air or coil temperatures and communicates this data to the main control board. By providing real-time thermal feedback, it allows your air conditioner to accurately regulate cooling cycles, prevent evaporator icing, and maintain your desired comfort level. A malfunctioning thermistor can lead to inaccurate temperature readings, short-cycling, or system error codes, making this genuine replacement essential for reliable climate control.

The EBG61108909 is engineered with a high-sensitivity thermal resistor protected by a specialized moisture-resistant coating. This ensures the sensor remains accurate and responsive even in the high-humidity environment of an active cooling unit. Its precision-molded connector provides a secure, vibration-resistant electrical connection to the main PCB, ensuring stable signal processing.

1. Safety First: Turn off the air conditioner and completely disconnect it from the power source (unplug it or switch off the dedicated circuit breaker).
2. Access the Sensor: Open the front intake grille and remove the air filters. The thermistor bulb is typically mounted in a plastic clip on the evaporator coil or positioned in the return air path.
3. Trace the Wiring: Follow the sensor wire back to the electrical control box where it connects to the main PCB.
4. Disconnect the Old Part: Open the control box cover and carefully unplug the EBG61108909 connector. Note the wire routing to ensure the new part is installed without being pinched.
5. Install the New Thermistor: Plug the new sensor into the correct port on the PCB. Route the lead wire along the original path and secure the sensor bulb into its mounting clip.
6. Reassemble and Test: Replace the control box cover, filters, and front grille. Restore power and verify that the unit accurately detects and responds to temperature changes.
