EBG61109832 Genuine NTC Discharge Pipe Thermistor for LG Air Conditioners, LG Outdoor Unit Discharge Temperature Sensor

EBG61109832 is a genuine LG thermistor assembly with a single NTC sensor, made to read the discharge pipe temperature in an LG air conditioner. The discharge pipe carries hot refrigerant gas out of the compressor, so this sensor is one of the main ways the outdoor board protects the compressor from overheating. Models aren't on file for this number, so match EBG61109832 to your old sensor before ordering.

Why the discharge sensor matters on an LG system

NTC means the sensor's resistance falls as it heats up. The board reads that change to track how hot the compressor's discharge gas is running. High discharge temperatures can point to low refrigerant, a blocked coil or a struggling compressor, so the board slows or stops the compressor if the reading climbs too far. A faulty sensor can trigger the same protection when nothing is wrong, giving you a system that starts, runs briefly and shuts down, cools or heats poorly, or shows a discharge sensor error. Testing its resistance against LG's table shows whether the sensor or the system is at fault.

Replacing the discharge pipe sensor

This work is inside the outdoor unit of a hard-wired system, so it should be done by a licensed electrician or qualified air conditioning technician. Isolate the unit and let the compressor and pipes cool, as the discharge line runs very hot. Fit the new sensor in the same holder on the discharge pipe, refit any insulation sleeve over it, and plug it into the same board connector.

Questions about this part

Does replacing this sensor involve the refrigerant?

No. The sensor sits in a holder on the outside of the discharge pipe, so the refrigerant circuit stays sealed. It's still a job for a qualified technician because of the mains wiring and hot pipework, and because a high discharge reading may point to a refrigerant problem that needs checking.
