LG Air Conditioner Error Code E361

E361 indicates an operation failure of inverter compressor 2 in your LG air conditioning system. The control board has detected that the second inverter-driven compressor is not functioning correctly and has shut down the system to prevent damage. This error points to a problem in the compressor itself, the inverter board driving it, the connecting wiring, or the refrigerant circuit.

No, you should not attempt to continue operating the unit when E361 is active. The system shuts down automatically to protect the compressor and inverter components from further damage. Repeatedly attempting to restart and run the unit without addressing the underlying fault can worsen the damage and increase repair costs significantly.

Repair costs vary widely depending on the root cause. If the fix is a wiring correction or refrigerant recharge, costs are typically in the range of $150 to $400. If the inverter PCB needs replacement, expect costs in the range of $300 to $700 including labor. Compressor replacement is the most expensive outcome, often ranging from $800 to $2,000 or more depending on the system size and labor rates in your area.

A basic power cycle is safe to attempt as a first step and may resolve the error if it was caused by a temporary electrical disturbance. However, diagnosing the root cause requires measuring compressor phase resistance with a multimeter, checking refrigerant pressures, and inspecting inverter board components, all of which require technical knowledge and proper tools. Refrigerant handling also requires EPA certification, so most repairs beyond a simple reset should be handled by a qualified technician.

A full power reset, turning the unit completely off at the breaker and restarting after a few minutes, is the recommended first diagnostic step. If the error was caused by a temporary power fluctuation, the reset may clear it. However, if there is an actual hardware fault such as failed compressor windings, a damaged inverter board, or low refrigerant, the error will return and must be properly diagnosed and repaired.
