What you can check yourself
0 / 4 checked
- Confirm the symptom: freezer still cold, fridge compartment warm, and listen for whether the compressor is running at all (a faint hum from the back/bottom of the unit).
- Check your model and serial number (inside the fridge, usually on a side wall) and look up your specific warranty terms directly on LG's website — don't assume it's expired without checking.
- Rule out the simpler cause first: a blocked vent or failed evaporator fan can cause a similar symptom and is a much cheaper fix — see our guide on a fridge not cooling with the freezer still working.
- If the compressor isn't running or humming at all, that's a stronger sign it's the compressor itself rather than airflow between compartments.
Still not working? A technician can take it from here.

Call a technician to confirm the diagnosis either way — compressor replacement and warranty claims both start with an accurate diagnosis, and guessing wrong wastes time on either path.
What's actually documented
LG's linear compressor, used in many French-door refrigerators, was the subject of a 2014–2017-era class action that settled in 2020, and a newer 2024 suit alleging ongoing compressor failures that stop cooling, covering some LG and Kenmore models (Kenmore refrigerators from this era were sometimes built by LG). One large retailer's service data found about 1.2% of 7,187 LG refrigerators sold between 2018 and 2024 needed a compressor replacement — a real but relatively small share of units.
Why the warranty check matters first
LG has offered extended compressor warranty coverage (commonly 10 years on many models) separate from the shorter standard appliance warranty — if your unit qualifies, the compressor and sometimes the labor may be covered directly by LG. That's worth confirming with LG using your model and serial number before paying for a repair out of pocket, since the terms and eligibility vary by model and purchase date.
A note on this brand's codes: Not every LG refrigerator uses the affected compressor design, and a warm fridge has other possible causes too — a technician diagnosis confirms which applies before any repair work starts.
