Quick answer: LG refrigerators 2014-2017 famously had linear compressor failures (settled in $1.9B class action). Other causes: dirty condenser coils, failed evaporator fan, or defrost system failure. Check serial number/build year before paying for repair — you may qualify for free fix.

Most likely culprit: Linear compressor failure (LG 2014-2017) OR dirty coils.
Time to fix: 15 min (coil clean) to professional repair (compressor).
If your LG fridge isn't cooling, FIRST check if it qualifies for the LG class-action lawsuit settlement (compressor issues 2014-2017 builds).
Cause 1 — LG linear compressor failure (40% if model from 2014-2017)
LG's linear compressor in fridges sold 2014-2017 had high failure rates. Settled $1.9B class action. Symptoms: fridge stops cooling, may make clicking sounds.
How to confirm:
- Find serial number (inside fridge or back panel).
- Visit lglaw.com/lglawsuit or call LG support — provide serial number.
- If qualifying, LG covers free or reduced-cost repair (parts + labor).
The fix: LG-authorized repair (free if eligible). DO NOT pay for compressor replacement out-of-pocket without checking eligibility first.
Cause 2 — Dirty condenser coils (30%)
Coils on bottom or back accumulate dust, blocking heat dissipation.
Fix: Pull fridge out, vacuum coils. Free, 15 min.
Cause 3 — Defrost system + evaporator fan (30%)
Same diagnosis as other brands — frost buildup blocks airflow OR fan failed.
Fix: Manual defrost (24h unplugged), replace defrost thermostat ($30-$50) or evap fan motor ($30-$60).

Frequently asked questions
Q: How do I find my LG fridge build year?
A: Serial number 4th-5th digits = year code. Or check warranty paperwork. LG website has VIN-style lookup.
Q: Class action expired?
A: Check current LG service notices. Some claims still active for newer compressor failures.
Q: Should I buy a new fridge instead?
A: NOT before checking eligibility. Free repair >>> $1500 new fridge.
Q: What if I don't qualify?
A: Compressor replacement $400-$800 + labor. New fridge often more economical at this point.
