LG Refrigerator Error Code 33 — Compressor Relay Failure
What this means
Error code 33, like error code 22, indicates a problem with the compressor relay. This relay controls power delivery to the compressor motor. When it fails, the compressor will not engage and the refrigerator cannot maintain cold temperatures. Code 33 specifically refers to a relay failure mode distinct from code 22 but requires the same repair approach.
