The 50% Rule, Explained
Appliance professionals use a simple benchmark: repair the refrigerator when the repair costs less than half the price of a comparable new unit. Below that line, repair almost always wins financially. Above it, the decision depends on age.
Age matters because a well-maintained LG refrigerator lasts 15–20 years. A $900 compressor job on a 6-year-old, $2,500 French-door model buys you many more years for about a third of replacement cost — an easy yes. The same $900 on a 15-year-old basic top-freezer is harder to justify.
One more factor people forget: a new refrigerator isn't just the sticker price. Delivery, haul-away of the old unit, and 3–10 days of living out of coolers all go on the "replace" side of the ledger.
Repair vs Replace: 2026 Costs
| Repair (typical LG cooling failure) | Replace with new | |
|---|---|---|
| Compressor part | $200 – $500 | — |
| Labor (3–4 hour job) | $500 – $850 | — |
| Typical total, installed | $700 – $1,250 | $1,500 – $3,000+ for a comparable French-door LG |
| Budget option | $399 — LG flat-rate program (parts + labor) | From ~$600 for an entry top-freezer |
| Delivery & haul-away | $0 | $50 – $200 |
| Time without a working fridge | Often same-day | 3 – 10 days for delivery |
| If the compressor is under LG's 10-year warranty | Parts — and often labor — may be $0 | Warranty value is forfeited |
| Extra life you get | 5 – 10 more years, typically | 15 – 20 years (new unit) |
Pricing as of July 2026. Sources: Angi, HomeGuide, LG flat-rate repair program. Your exact repair cost depends on the diagnosis — see below.
Book a diagnosis — you only pay for the repair you needWhen repair is clearly the right call
- Your fridge is under about 10 years old
- It's the first major failure (compressor, start relay, fan motor, control board)
- It's a 2014–2022 model — the linear compressor may still be under LG's 10-year warranty
- It's a high-end, counter-depth, or built-in model where replacement costs multiply
- The built-in dimensions or panel-ready design make replacement complicated
When replacement makes more sense
- The refrigerator is 12–15+ years old
- This is the second major failure within two years
- The sealed system has rust or leak damage beyond economical repair
- Parts for your model are discontinued and unavailable
- It's a very old, inefficient unit where energy savings offset part of the new-fridge cost
If any of these describe your situation, we'll say so at the diagnosis — that's our honest-recommendations promise. We'd rather tell you to buy a new fridge than sell you a repair that doesn't make sense.
The LG 10-Year Compressor Warranty Most Owners Don't Know About
LG's inverter linear compressor — the usual suspect when an LG fridge stops cooling — carries a 10-year parts warranty from the date of purchase. And following LG's class-action settlement, coverage for many models manufactured between 2014 and 2022 was expanded to include both parts and labor for the full 10 years.
To check eligibility: photograph the data plate inside the fresh-food compartment (model and serial number), find your purchase receipt if you have it, and call LG at 1-800-243-0000. For out-of-warranty situations, LG also runs a $399 flat-rate repair program covering parts and labor through its own network.
Our honest take: if your fridge qualifies for free LG warranty service, we'll tell you at diagnosis and help you route the claim — that costs us a job, but it's the right call. Where we earn your business: when LG's schedule is booked out for days while your food spoils, when your model is outside the warranty window, or when the failure isn't the compressor at all.
Why the Diagnosis Changes the Math
"Not cooling" has at least six different causes — failed compressor, start relay, fan motor, refrigerant leak, control board, thermostat — and their repair costs differ by hundreds of dollars. A $150 start-relay fix and a $1,100 compressor job produce the exact same warm milk.
That's why guessing is expensive in both directions: replace the fridge over a relay and you've wasted $2,000; throw parts at a dying compressor and you've wasted weeks. If you're seeing any of the five warning signs, a professional diagnosis pins down the real cause before you spend anything on parts — or on a new refrigerator.
Typical repair cost by cause
| Failure | Typical installed cost | Verdict vs replacement |
|---|---|---|
| Start relay | $150 – $300 | Always repair — a fraction of any new fridge |
| Evaporator / condenser fan motor | $200 – $400 | Almost always repair |
| Thermostat / sensor | $150 – $350 | Almost always repair |
| Control board | $300 – $600 | Repair unless the unit is 15+ years old |
| Compressor (sealed system) | $700 – $1,250 | Apply the 50% rule — and check the 10-year warranty first |
| Refrigerant leak in sealed system | $400 – $1,000+ | Depends on leak location — diagnosis decides |

Book a same-day diagnosisFrequently Asked Questions
As of 2026, an LG compressor replacement typically costs $700–$1,250 installed (part $200–$500 plus labor). Simpler causes like a start relay or fan motor cost considerably less, which is why a professional diagnosis comes first. LG also offers a $399 flat-rate repair program for qualifying situations.
Usually yes for parts: LG's linear compressor carries a 10-year parts warranty, and many models manufactured 2014–2022 have expanded coverage that includes labor following LG's class-action settlement. Check your model's data plate and purchase date, or call LG at 1-800-243-0000.
The job itself takes about 3–4 hours. With same-day service and stocked parts, many Bay Area repairs are completed the day you call, compared with a 3–10 day wait for a new refrigerator delivery.
Apply the 50% rule: repair if the cost is under half the price of a comparable new unit. LG refrigerators last 15–20 years with maintenance, so a single failure at 10 years is often still worth repairing — especially for high-end or built-in models where replacement costs multiply.
Yes — LG's flat-rate program covers qualifying out-of-warranty repairs scheduled through LG's own service network. It can be good value when you can wait for LG's scheduling. When your food is spoiling and you need someone today, or your model doesn't qualify, that's when a local same-day specialist makes more sense.
The Verdict
Under 10 years old with a first major failure? Repair. Made 2014–2022? Check the warranty before paying anyone. Over 12–15 years with repeat failures? Put the money toward a new unit.
Not sure which bucket you're in? That's exactly what the diagnosis is for. Same-day service across all nine Bay Area counties.
