LG Linear Compressor failures display as error codes 22 or 33. Consumer Reports shows 8% failure rate vs 3% industry average. Warranty covers parts+labor years 1-5, parts only years 6-10 (you pay $500+ labor). Multiple class actions are ongoing. Professional service is required—no DIY fix exists.

LG’s Linear Compressor technology has been marketed as more efficient and durable than conventional compressors. However, significant reliability issues have led to multiple class action lawsuits and a failure rate nearly three times the industry average.
How Linear Compressor Technology Works
LG’s Linear Compressor uses an electromagnetic piston that moves in a straight line rather than converting rotary motor motion through a crankshaft. This eliminates the crankshaft, connecting rod, and rotary motor found in conventional compressors.
Claimed benefits:
- 20-30% greater energy efficiency
- 15% quieter operation
- ±0.5°C temperature precision
- 20-year durability (European marketing claim)
Reality: Consumer Reports survey data shows 8% of LG French-door refrigerators had compressor problems compared to the 3% industry average.
Symptoms of Linear Compressor Failure
Early Warning Signs
- Gradually increasing run time (near-continuous operation)
- Food spoiling faster than usual
- Fridge feels warm but display shows normal temperatures
Definite Failure Indicators
- Clicking sounds — Extremely common; compressor trying but failing to start
- Not cooling despite lights and fans working
- Compressor running constantly without cooling
- Short cycling — Runs briefly, then stops
- Loud buzzing/humming from compressor area
- Back freezer wall shows no frost pattern
- Compressor feels extremely hot OR ice cold (should be warm)
Error Codes
| Code | Meaning |
|---|---|
| 22 | Compressor relay problem |
| 33 | Compressor relay problem |
LG states: “There are no troubleshooting steps to resolve this issue.”
Warranty Coverage Details
LG provides a 10-year warranty on the Linear/Inverter Compressor, but coverage changes significantly after year 5:
| Component | Years 1-5 | Years 6-10 |
|---|---|---|
| Linear/Inverter Compressor | Parts AND labor | Parts ONLY |
| Sealed System (condenser, dryer, tubes, evaporator) | Parts and labor | Not covered |
| General refrigerator parts | Year 1 only | Not covered |
Critical: In years 6-10, you pay labor costs—typically $500-$850 for compressor replacement. The “10-year warranty” provides less protection than many consumers realize.
Checking Warranty Status
Call 1-800-243-0000 with:
- Model number
- Serial number
- Proof of purchase (receipt)
Or visit lg.com/us/support and start a service request.
Keep your original purchase receipt. Without proof of purchase date, LG uses the manufacture date, which may result in less warranty coverage than you’re entitled to.
Compressor Replacement Economics
| Cost Component | Range |
|---|---|
| Compressor part only | $200-$500 |
| Labor | $500-$850 |
| Total professional replacement | $700-$1,250 |
| Additional parts (filter drier, relay, capacitor) | $50-$150 |
When Repair Makes Sense
| Refrigerator Age | Recommendation |
|---|---|
| Under 5 years | Repair under warranty (parts+labor covered) |
| 5-8 years | Repair if under warranty (labor cost analysis) |
| 8-10 years | Compare repair cost to new refrigerator |
| 10+ years | Usually replace rather than repair |
Class Action Information

For Affected Consumers
If your LG Linear Compressor has failed:
- Keep all documentation: Receipts, repair invoices, photos, LG communications
- Document food loss: Take photos, keep receipts for spoiled food
- Search “LG refrigerator class action 2025” for current case information
- Consider consulting with attorneys handling these cases
Why DIY Repair Is Not Possible
Compressor replacement requires:
- EPA Section 608 certification to handle refrigerants
- Specialized brazing equipment
- Vacuum pump
- Refrigerant gauges
- Precise charging scales
Improper installation leads to premature re-failure and potential refrigerant leaks. This is not a DIY repair under any circumstances.
What To Do If Your Compressor Fails
Step 1: Document Everything
- Note the date symptoms started
- Record error codes
- Take photos and videos
- Keep temperature logs if possible
Step 2: Check Warranty Status
Call LG (1-800-243-0000) with model/serial numbers and proof of purchase.
Step 3: Request Authorized Service
Schedule service through LG or an LG-authorized service provider. Even in years 6-10, the compressor part is covered.
Step 4: Consider Your Options
If out of warranty or facing significant labor costs:
- Get multiple repair quotes
- Compare repair cost to replacement cost
- Factor in the refrigerator’s age and condition
- Consider whether you want another LG given the track record
Model Coverage
Linear Compressor issues affect most LG refrigerators manufactured since 2014:
- French Door: LRMVS, LRMVC, LRFXS, LFX series
- Side-by-Side: LRSXS, LRSVS series
- InstaView: All models with Linear Compressor
- Counter-Depth: All models with Linear Compressor
Check your model specifications to confirm if it has a Linear Compressor.
