Samsung Air Conditioner Error Code OUTDOOR_GREEN_RED_ON

This error code indicates that the compressor overcurrent protection circuit has been triggered. The outdoor unit detected that the compressor was drawing more current than the safe operating limit allows and shut down to prevent damage. Both the green and red LEDs on the outdoor unit illuminate simultaneously to signal this condition. The underlying cause can be an airflow restriction, an incorrect refrigerant charge, a weak capacitor, or a compressor that is mechanically or electrically degraded.

No. The system has already shut the compressor down as a protective measure, and attempting to force the unit to run before diagnosing the root cause risks permanent compressor damage or an electrical fault. Leave the unit off until the underlying problem has been identified and corrected.

Repair costs depend entirely on the root cause. A condenser coil cleaning and refrigerant recharge typically falls in the range of $150 to $400. Replacing a run or start capacitor generally costs $100 to $250 including labor. Compressor replacement is the most expensive scenario, typically ranging from $800 to $2,000 or more depending on the unit size and labor rates in your area.

Some of the causes are addressable without professional tools. You can clean the condenser coil, remove obstructions from around the outdoor unit, and check that the installation site has adequate ventilation without specialized equipment. However, checking refrigerant pressures requires a manifold gauge set and EPA Section 608 certification, and testing or replacing a compressor or capacitor is best handled by a qualified HVAC technician.

A power reset may temporarily clear the error and allow the unit to restart, but if the underlying cause has not been addressed, the overcurrent condition will recur and the code will return. Repeated compressor restarts into an overcurrent condition accelerate motor winding wear and can lead to complete compressor failure. Reset should only be used as part of a diagnostic process, not as a long-term fix.
