      If the compressor of your LG refrigerator isn't running, the starting devices may be shorted, open, or broken. Also, the OLP could be shorted, or the compressor coil could be open or shorted. A wiring harness with poor contact or shorts could also be the cause. Replace the indicated component to resolve this issue.
