Warranty Service
If your LG fridge stopped cooling with the freezer warming up, you're likely looking at a linear-compressor failure. The good news: LG offers a 10-year parts warranty on the linear compressor, depending on model and serial number. We diagnose the failure, help you open the claim with LG, 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 offers a 10-year parts warranty on the linear compressor, with coverage depending on the model and serial number. 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 check the serial number with you on-site, help you open the claim with LG, install the OEM compressor, and verify sustained cooling. Total elapsed time depends on how quickly the part ships.
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 CO is a compressor or inverter communication error, and Er CF points to the condenser fan. We diagnose which part failed. A compressor failure may be covered by LG's 10-year compressor parts warranty, depending on your model and serial number.
The inverter board is trying to start the compressor and the compressor is not running. A seized linear compressor is one possible cause and a failed inverter board is another, so we test before replacing anything.
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 inverter board, 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 read the serial with you and help you confirm with LG that 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.
Once LG approves the parts claim, the OEM compressor ships (timing varies by model). When 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 the refrigerant type and charge listed on the unit's data tag, 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 CO is a compressor or inverter communication error, so it points to the linear compressor or its inverter board. Er CF points to the condenser fan. We diagnose which part failed before quoting, and a confirmed compressor failure may qualify for LG's 10-year compressor parts warranty depending on your model and serial number.
If your compressor is covered by LG's 10-year parts warranty, the part is covered. 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 (shipping time varies), 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 the refrigerant type and charge listed on the unit's data tag. We return at 24 hours to verify sustained pull-down if needed.
Rarely. LG's standard warranty remedy is a replacement compressor, not a new refrigerator. Check lg.com for any current settlement or extended-warranty program that covers your model. If the replacement compressor also fails within the original 10-year window, the part is still covered, but 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.
We read the serial number with you, document the diagnosis and failure data, and help you open the LG parts-warranty claim. You approve a written quote for labor before we proceed.
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. Some calls that look like a compressor failure turn out to be a failed inverter board, condenser fan motor, or refrigerant leak. Those are paid repairs but often 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 early; we run 7am–9pm every day. The compressor install itself happens after the part ships (timing varies).
Yes — 1-year written labor warranty on our install work. LG's compressor part carries the remainder of their 10-year sealed-system warranty.
