The 22 error means your LG refrigerator has detected a problem with the compressor relay — the electrical component that controls power delivery to the compressor. The compressor is the heart of the cooling system and without a functioning relay it cannot start or run correctly. This means the refrigerator will stop cooling entirely. There are no user steps to resolve this error and the unit requires a professional repair service to inspect and replace the faulty relay or compressor components.
