LG Air Conditioner Thermistor - 6323A20004P

Maintain the cooling accuracy and operational safety of your system with the LG 6323A20004P Air Conditioner Thermistor. This precision sensor serves as the "eyes" of your unit's control board, constantly monitoring the temperature of the evaporator coils or the ambient intake air. By converting thermal readings into electrical resistance, it tells the main PCB when to engage the compressor, adjust the fan speed, or trigger a defrost cycle. If your air conditioner is blowing warm air, short-cycling, or displaying sensor-related error codes, this genuine replacement part is the critical fix.

The 6323A20004P is engineered with a high-sensitivity thermal resistor encapsulated in a moisture-sealed, protective coating. This design ensures that the sensor remains highly accurate even in the high-humidity, high-condensation environment of an active air handler, preventing the "signal drift" or intermittent faults that often plague generic aftermarket sensors.

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 Interior: Open the front intake grille and remove the air filters. The thermistor bulb is typically clipped directly onto the copper evaporator coils or held in a bracket 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 6323A20004P connector from the circuit board. Note the wire routing to ensure the new part 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 panel. Restore power and verify the unit accurately detects and maintains the set temperature without triggering error codes.
