LG Air Conditioner Error Code E130

E130 means the LG indoor unit has detected that both heat exchanger sensors, the EVA IN and EVA OUT thermistors, are simultaneously disconnected or out of position. These sensors monitor refrigerant temperatures at the inlet and outlet of the indoor evaporator coil. The system shuts down when both sensors are lost because it cannot safely regulate operation without that temperature data. The most likely cause is that the sensors were physically dislodged from their mounting positions on the coil.

No, you should not continue running the air conditioner while E130 is active. The system needs both heat exchanger sensors to prevent coil freeze-up and to protect the compressor from operating under unsafe refrigerant conditions. Running the unit without this data risks ice formation on the coil and potential compressor damage.

If the sensors only need to be reseated, the repair cost may be limited to a service call fee, typically in the range of $75 to $150 depending on your location. If one or both thermistor sensors require replacement, parts and labor combined could range from $100 to $300. A control board replacement, if needed, would be significantly more expensive and is an uncommon outcome for this fault.

In many cases, yes. If the sensors have simply been knocked loose, a knowledgeable DIYer can open the indoor unit panel, locate the EVA IN and EVA OUT sensor clips on the evaporator coil, and reseat both sensors into their correct positions. However, if the sensor wires are damaged or the control board requires inspection, it is safer to call a qualified technician.

A simple power reset will not permanently clear E130 if the underlying sensor issue has not been resolved. The code will return as soon as the control board checks the sensor inputs again. The sensors must be physically reseated and confirmed to be reading correctly before the fault will clear and stay cleared.
