Sorry, there was a problem. Please try again later.Hi, there. Thank you for reaching out to us regarding your LG Refrigerator (LRDCS2603S) model. The intermittent 15-second humming noise you hear from your refrigerator is likely just the compressor adjusting its speed and does not indicate a problem with the appliance. As long as the noise is not excessive, it is considered normal behavior.
