LG Air Conditioner NTC Thermistor - EBG61325805

Restore consistent cooling and prevent system errors with the LG EBG61325805 Air Conditioner NTC Thermistor. This Negative Temperature Coefficient (NTC) sensor acts as the primary thermal monitor for your unit's control system. By providing real-time resistance data to the main PCB, it ensures the compressor and fan operate at the correct intervals to maintain your desired room temperature. If your air conditioner is displaying sensor-related error codes (such as CH01 or CH02), failing to cycle the compressor, or blowing air that doesn't match the set temperature, this genuine sensor is the critical fix.

The EBG61325805 is engineered with high-sensitivity thermal components and a moisture-sealed, protective coating. This design allows the sensor to remain highly accurate even when exposed to the constant condensation and temperature fluctuations of the evaporator coils, ensuring long-term reliability and peak energy efficiency.

1. Safety First: Turn off the air conditioner and disconnect it from the power source (unplug it or switch off the dedicated circuit breaker).
2. Access the Interior: Open the front intake grille and remove the air filters. The thermistor bulb is typically mounted in a plastic clip directly on the copper evaporator coils or positioned in the return air stream.
3. Trace the Wiring: Follow the sensor wire back to the electrical control box where it connects to the main circuit board.
4. Disconnect the Old Part: Open the control box cover and carefully unplug the EBG61325805 connector from the PCB. Note the wire routing to ensure the replacement is not pinched during reassembly.
5. Install the New Thermistor: Plug the new sensor connector into the correct port. Route the lead wire along the original path and snap the sensor bulb securely into its designated 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.
