Samsung Air Conditioner Error Code E467

E467 means the air conditioner has detected an unconnected or open wire on the compressor 1 circuit. The control board monitors the compressor wiring and shuts down operation when it cannot confirm a proper connection. This fault is intended to protect the compressor from running without a verified electrical circuit. A technician should inspect the compressor wiring harness and all related connectors as the first step.

No. When E467 is active, the system has already disabled the compressor to protect it from damage. Attempting to override or ignore the fault and run the unit could cause further damage to the compressor or the control board. The unit should remain off until the wiring fault has been identified and corrected by a qualified technician.

Repair costs depend on the specific cause of the fault. If the fix is simply reseating a loose connector, the cost may be limited to a service call fee, typically in the range of $75 to $150. If a wiring harness needs replacement, costs could range from $150 to $400 or more depending on labor and part pricing. A control board replacement, if needed, can push total costs higher, often in the $300 to $700 range or beyond depending on the model.

A knowledgeable DIYer can visually inspect the outdoor unit for obvious disconnected or loose wiring connectors, but working on compressor wiring involves high-voltage components and refrigerant-handling equipment. If the fix involves anything beyond reseating a clearly disconnected plug, it is strongly recommended to have a certified HVAC technician perform the repair. Improper handling of compressor wiring can result in electrical shock or equipment damage.

A power reset may temporarily clear the fault code from the display, but if the underlying wiring connection issue is not resolved, E467 will return as soon as the system attempts to operate the compressor. A reset does not fix a physical wiring problem. The root cause must be identified and repaired before the unit will operate normally.
