LG’s linear compressor settlement covers a specific window of units, and if your fridge just died, you need to know whether you’re in that window before you spend anything on repairs.
What the Settlement Actually Covers
LG faced a class action over linear compressor failures (Rosen v. LG Electronics), which received final approval in December 2020. The original settlement covered refrigerators manufactured between January 1, 2014 and December 31, 2017. Following the settlement, LG extended its Inverter Linear Compressor warranty to cover both parts and labor for 10 years from the purchase date on models manufactured between 2014 and 2022.
This is a significant change from the original warranty terms, which covered parts but left owners with a labor bill of several hundred dollars. The updated coverage means that if you bought a qualifying unit and the compressor fails within 10 years, LG is supposed to cover both the part and the labor.
What it doesn’t cover: refrigerators outside that purchase window, units where the owner can’t document the original purchase date, and failures caused by anything other than the compressor itself (sealed system leaks, control board failures, ice maker problems). Eligibility depends on your specific model and serial number.
To check your unit, visit LG’s website directly and enter your serial number, or call 1-800-243-0000. Don’t rely on secondhand information about whether your model qualifies.
Why the Linear Compressor Fails So Often
The linear compressor design was supposed to be more efficient and quieter than a conventional rotary compressor. It moves in a straight line instead of rotating, which reduces friction. In theory, that means longer life and lower energy use.
In practice, a significant number of units developed failures within five to ten years, well before the expected lifespan of a refrigerator. The failure mode is usually the same: the compressor loses its ability to compress refrigerant. The fridge stops cooling, sometimes gradually over a few days, sometimes overnight.
The root cause isn’t fully public, but field experience points to the oil return path in the linear compressor being less forgiving than in a rotary design. If the refrigerant charge isn’t exactly right (from the factory or after a prior repair), oil can migrate into parts of the system where it doesn’t belong, degrading the compressor over time. LG acknowledged the issue indirectly through multiple warranty extensions and the settlement itself.
How a Tech Diagnoses It
When I see a dead LG with a linear compressor, the diagnostic steps are pretty consistent.
First, listen to the compressor. A failing linear compressor often clicks on and runs for a short time, then shuts off. Sometimes it makes a low humming sound but never builds pressure. Sometimes it’s completely silent when it should be running.
A tech will check voltage at the compressor terminals to confirm the control board is sending the start signal. Then they’ll check running amperage. A healthy linear compressor draws within a specific range for the model. One drawing too high is working against itself and will fail soon. One drawing almost nothing is already gone.
The next step is the sealed system. That means checking refrigerant pressure. A loss of refrigerant can mimic a compressor failure, but a sealed system leak is a different repair. If the system is fully charged and the compressor still won’t build pressure, the compressor is confirmed bad.
That full diagnostic usually takes 30 to 45 minutes for an experienced tech. Skipping it is how people end up replacing a compressor when the real problem was a refrigerant leak, or vice versa.
What the Repair Actually Involves
Any work on the sealed refrigerant system requires EPA 608 certification to legally handle refrigerants. The compressor swap itself needs brazing equipment and a vacuum pump to properly evacuate and recharge the system. A bad recharge is one of the things that kills a replacement compressor early, so getting the charge right isn’t optional.
Before calling, there are a few things you can check yourself: confirm the fridge has power, make sure the condenser coils (back lower panel or underneath) aren’t heavily clogged with dust (a blocked coil causes the compressor to overheat and trip out on thermal protection), and check that the door seals are closing properly. If those all check out and it’s still not cooling, it needs a tech.
If your unit qualifies under LG’s warranty or settlement terms, LG may send an authorized service provider. If it doesn’t, or if you want an independent diagnosis, call us.
The Repair vs. Replace Question
This is the real decision most people are facing.
A linear compressor replacement on an out-of-warranty LG runs anywhere from a few hundred to over a thousand dollars depending on parts, labor, and whether sealed system work is needed. Get a quote before deciding, and ask specifically whether the tech is replacing just the compressor or also checking the sealed system for leaks.
If the unit qualifies under LG’s extended 10-year coverage, both parts and labor may be covered. Worth checking before paying anyone.
A refrigerator that’s eight or more years old and already had one compressor failure is a harder case. It might make more sense to put that money toward a replacement unit rather than into a second repair on aging equipment. A good tech will give you an honest read on that rather than just selling you the repair.
When to Call a Pro
Start by checking your warranty eligibility. Use your serial number at LG’s website or call 1-800-243-0000. If your unit qualifies under the extended 10-year coverage, follow LG’s process before paying anyone out of pocket.
If it doesn’t qualify, or if you want an independent read on what’s actually wrong, call a tech. A proper diagnosis tells you whether it’s the compressor, a sealed system leak, or something else entirely, and gives you a real number to compare against replacement cost before you commit to anything.
