Samsung Air Conditioner Error Code YEL_FLICKER_RED_ON_GRN_ON

This code indicates a compressor rotation error, meaning the control board detected that the compressor is not spinning correctly after receiving a start command. The LED pattern (yellow flickering, red on, green on) is how the Samsung unit signals this specific fault. The first step is to inspect the compressor TAB terminal connections and the wire connectors leading to the control box.

No. When this fault is active, the system has already shut down the compressor to prevent damage. Attempting to force the unit to run without resolving the underlying issue can damage the compressor motor windings or other electrical components. The unit should remain off until the fault is diagnosed and repaired.

Repair costs vary widely depending on the root cause. Fixing a loose or corroded terminal connection is typically inexpensive, often in the range of a standard service call fee of $75 to $150. Replacing a control board generally costs between $200 and $500 including parts and labor. A failed compressor is the most expensive outcome, with replacement costs commonly ranging from $600 to $1,500 or more depending on unit size and refrigerant type.

A homeowner can safely inspect visible wire connectors for obvious looseness or damage, but diagnosing and repairing the compressor, control board, or internal wiring typically requires a trained HVAC technician. Working around high-voltage components and refrigerant systems carries significant safety risks. If the issue is simply a loose connector, reseating it may resolve the fault, but further diagnosis should be left to a professional.

A power reset may temporarily clear the fault display, but the error will return if the root cause has not been corrected. Because this fault points to a real mechanical or electrical condition, resetting without repair is not a lasting solution and could allow further damage to occur.
