If your LG fridge stopped cooling with the freezer warming up, you're likely looking at a linear-compressor failure. The good news: LG's 10-year sealed-system warranty covers the compressor part on most LG fridges built since 2014. We file the warranty claim, install the OEM compressor, and you pay labor only — typically $385–$575 all-in. Part of our full LG fridge repair coverage.

Quick answer
LG's 10-year sealed-system warranty covers the linear compressor part on most LG fridges built since 2014. Your out-of-pocket on a warranty job is the labor only — typically $385–$575 in the Twin Cities (the flat $149 trip fee is credited toward labor). We confirm the warranty by serial number on-site, file the claim with LG, install the OEM compressor, and verify sustained cooling. Total elapsed time is usually 7–10 days (3–7 for the part to ship + 1 day for the install).
How linear-compressor failure presents
Classic linear-compressor failure pattern. The compressor still hums but isn't pumping refrigerant. You'll see the freezer slowly warm above 0°F over 12–24 hours while everything electrical still works normally.
Er CF = compressor fan fault. Er Co = compressor lock. Both point to the linear compressor or its inverter board. Both are covered if your fridge is within the 10-year sealed-system warranty.
The inverter board is trying to start the compressor; the compressor's piston has seized. Same root cause as Er Co — the linear motor that drives the piston has failed.
Sudden full failure is the most common LG linear-compressor presentation — they don't slowly degrade. One day fine, next day everything is warm.
The process
We confirm the failure is the linear compressor (not the start relay, not the condenser fan, not a refrigerant leak). LG's warranty only covers the compressor itself — if the fault is elsewhere we tell you on-site.
LG's 10-year sealed-system warranty (covering the linear compressor) runs from the original purchase date. We pull the serial, contact LG, and confirm the part is covered before any work is approved.
LG covers the compressor part under warranty; labor is the homeowner's cost. Linear-compressor replacement labor in the Twin Cities runs $385–$575 depending on model (French-door is harder than side-by-side because of the bottom-mount layout). You approve in writing before we order.
LG ships the warranty compressor in 3–7 business days to our shop. Once it arrives we schedule the install — typically a 3–4 hour job because the sealed system must be recovered, evacuated, and recharged per EPA Section 608.
We recover the existing refrigerant, swap the compressor, pull vacuum to 500 microns, recharge with R-600a per LG's exact charge spec, and verify pull-down. We return at 24 hours if needed to confirm sustained cooling.
FAQs
LG's 10-year sealed-system warranty covers the linear compressor part on most LG refrigerators sold from 2014 onward — French-door, side-by-side, top-mount, and counter-depth. The warranty runs from the original purchase date and covers the compressor only (not labor, not the inverter board, not other failed components). We pull your serial and confirm warranty status on-site before any work is approved.
Er CF = compressor fan fault. Er Co = compressor lock (the linear piston has seized). Both are linear-compressor faults and both typically qualify for the 10-year warranty replacement. The codes appear on the dispenser display or, on units without a display, by a slow blinking pattern on the icemaker LED.
If your fridge is within LG's 10-year sealed-system warranty, the compressor part is free from LG. Labor runs $385–$575 depending on model (the flat $149 trip fee is credited toward the labor cost). Total out-of-pocket on a warranty claim is typically $385–$575. If you're past 10 years and need a paid replacement, the compressor itself runs $385–$525 and total job is $785–$1,150.
Once the compressor arrives from LG (3–7 business days), the install is 3–4 hours on-site. The sealed system must be recovered, the old compressor removed, the new one brazed in, the system pulled to deep vacuum (500 microns), and recharged with R-600a per LG's exact charge spec. We return at 24 hours to verify sustained pull-down if needed.
Almost never. The 2020 LG linear-compressor class-action settlement closed and is no longer accepting claims. LG's current remedy is the warranty compressor replacement — they will not replace the unit. If the replacement compressor also fails within the original 10-year window, the part is still covered; another labor bill applies.
If you're within the 10-year warranty and the fridge is otherwise good, almost always repair — total cost is $385–$575 vs. $1,800–$3,500 for a comparable replacement fridge. If you're past 10 years and looking at $785–$1,150 for the compressor job, the math is closer; we'll walk through your specific model on-site.
Yes — all our techs are EPA Section 608 Universal certified, which is required for any refrigerant recovery, evacuation, and recharge work. We do not sublet sealed-system work and we do not vent refrigerant.
Yes — we pull the serial, contact LG with the failure data, get the warranty compressor authorized, and order the part. You sign a written quote for labor before we proceed; we handle the rest.
Most LG refrigerators with linear compressors (LFXS, LFXC, LFCS, LSXS, LRMVS, LRFVS, LRFXS, LRMDS, LMXS, LMXC, LRFCS, LFCC, LRSDS, LRSPC, LRMVC and Kenmore Elite refrigerators built by LG with model numbers starting 795.7 or 795.4). We confirm the warranty status by serial number on-site.
We tell you on-site. About 15% of "compressor failure" calls turn out to be a failed start relay, condenser fan motor, or inverter board — all paid repairs but much cheaper than a compressor job. The $149 trip fee covers the diagnostic either way and is credited to whatever repair you approve.
Same-day diagnostic windows are available across the Twin Cities when you call before 2pm on a weekday. The compressor install itself happens after LG ships the part (3–7 business days from authorization).
Yes — 1-year written labor warranty on our install work. LG's compressor part carries the remainder of their 10-year sealed-system warranty.
