Samsung Air Conditioner Error Code OUTDOOR_YELLOW_FLICKER_GREEN_ON

This LED pattern indicates an OPTION error related to the EEPROM on the outdoor unit's control board. The EEPROM stores configuration and option code data that the unit needs to operate correctly. When this data is missing, corrupted, or unreadable, the outdoor unit triggers this specific fault. A technician should check and verify the PCB option code as the first step in diagnosing this error.

The outdoor unit is unlikely to operate normally while this EEPROM option error is active, as the control board cannot confirm its own configuration. Attempting to run the system in this state is not recommended and could potentially cause additional issues. The unit should be inspected and repaired before returning to normal operation.

Repair costs vary depending on whether the fix requires only reprogramming the option code or a full outdoor unit PCB replacement. Labor for diagnosis and reprogramming is generally less expensive, while PCB replacement including parts and labor can range from a few hundred dollars to over five hundred dollars depending on the model and local service rates. Getting a diagnostic quote from a certified Samsung technician is the best way to determine the actual cost for your specific unit.

This error requires accessing and evaluating the outdoor unit PCB, which involves working with electrical components inside the outdoor unit. DIY repair is not recommended unless you have experience with HVAC electronics and understand the risks of working near capacitors and high-voltage components. A qualified technician can check the option code and determine whether reprogramming or board replacement is needed.

A simple power reset is unlikely to permanently clear this error if the underlying EEPROM data is corrupted or missing, since the fault condition will persist as long as the option code cannot be read correctly. A reset may temporarily clear the displayed fault, but the error will return when the unit powers back up and fails to validate its configuration. The root cause on the PCB must be addressed to fully resolve the fault.
