Samsung Air Conditioner Error Code E367

E367 is a fault code indicating that the control system has detected an unconnected or open-circuit wiring condition at the second compressor. The system generates this code to prevent compressor 2 from attempting to operate without a complete electrical connection. It requires inspection of the wiring harness, connectors, and compressor terminals to identify and correct the fault.

No, you should not continue operating the unit while E367 is active. The error indicates an electrical wiring fault at a compressor, and running the system in this state could cause further damage to the wiring, the control board, or the compressor itself. Turn off the unit and have it inspected by a technician before resuming use.

Repair costs depend on what caused the fault. If only a connector needs reseating or a short wiring section needs replacement, costs may range from roughly $75 to $200 including labor. If the compressor itself has failed due to an open motor winding, replacement costs can range from $400 to $1,200 or more depending on the unit size, compressor model, and labor rates in your area.

Diagnosing E367 involves working with high-voltage components inside the air conditioner, including the inverter board and compressor wiring, which carry potentially lethal voltages. A licensed HVAC or appliance technician should perform this repair. A knowledgeable technician can systematically check wiring connections, perform continuity tests, and determine whether the issue is a simple connector reseating or a component replacement.

A power reset may temporarily clear the code from the display, but it will return if the underlying wiring fault is still present. The error is triggered by a real circuit condition that the control board continuously monitors, so resetting the unit without fixing the wiring problem will not resolve the issue.
