LG LFXS26973S Repair Guide
A popular LG french-door running the linear inverter compressor — the technology behind both LG’s efficiency claims and its most famous reliability saga. Early linear compressors failed young enough to spark a class action; LG responded with a 10-year compressor part warranty and revised designs. Know the warranty before paying for anything sealed-system on this box.

Tech notes
For any not-cooling complaint: get LG to confirm compressor warranty status FIRST (10-year part coverage from purchase). Reputable servicers know the drill; walk away from any quote that prices a full compressor job without mentioning the warranty.
