Samsung Air Conditioner Error Code OUTDOOR_YELLOW_GREEN_RED_FLICKER

This error code indicates that the outdoor unit's over current protection has been activated. The control board detected that electrical current in the outdoor unit exceeded safe operating limits and shut the system down to prevent component damage. The yellow, green, and red LED flicker pattern on the outdoor unit is how Samsung signals this specific fault condition.

No. The over current protection exists to prevent serious damage to the compressor, motor windings, and control electronics. Attempting to bypass or repeatedly reset the unit without identifying the root cause risks permanent component failure and could create an electrical hazard. The system should remain off until the fault is properly diagnosed and corrected.

Repair costs vary widely depending on the root cause. A simple service call to check airflow and connections might run between $75 and $150. Refrigerant recharge services typically range from $150 to $400 depending on refrigerant type and quantity. Fan motor replacement can cost between $200 and $500 including labor, while compressor replacement is significantly more expensive, often ranging from $800 to $2,000 or more depending on the unit size and model.

Some causes, such as clearing debris from around the outdoor unit to restore airflow, can be addressed without professional tools. However, diagnosing and correcting refrigerant charge issues, compressor problems, fan motor failures, or current sensor faults requires specialized equipment and training. A certified HVAC technician should handle anything beyond basic airflow inspection.

A power reset may temporarily clear the fault and allow the unit to restart, but if the underlying cause is not resolved, the error will return. In cases involving a failing compressor, low refrigerant, or a defective sensor, the unit will likely shut down again shortly after restarting. Resetting without diagnosis is not a fix.
