LG refrigerator repair
Same-day LG refrigerator repair across San Mateo and Santa Clara counties. We specialize in LG not-cooling, linear-compressor and sealed-system faults, ice makers, leaks and control boards. $100 diagnostic — waived when you proceed with the repair.
Fridge not cooling? On LG refrigerators it is almost always the linear compressor — and we replace it same-day, often covered by LG’s 10-year compressor warranty.
Signs you need this repair
- Fridge and freezer both getting warm
- Food spoiling — milk warm, ice cream melting
- Compressor runs nonstop but no cold air
- No hum from the compressor, or a click then silence
- Not holding temperature / a cooling error on the display
- Unit is roughly 2–8 years old (peak failure window)
Why LG refrigerators stop cooling — the linear compressor
LG pioneered the linear (inverter) compressor, and on many 2014–2019 models it is the number-one failure. When it goes, the fridge and freezer warm up at the same time. This is a sealed-system repair — the refrigerant loop has to be recovered, the compressor replaced, and the system re-charged. That takes a certified technician and recovery equipment (R-134a systems legally require EPA-608 certification, and newer R-600a systems use a flammable refrigerant), so it is not a DIY or handyman job.
Good news: LG’s 10-year linear-compressor warranty
Most LG refrigerators carry a 10-year warranty on the linear compressor part. If yours qualifies, the compressor itself is covered — you typically pay only the diagnostic and labor. We read your model and serial off the sticker inside the fridge, confirm coverage in minutes, and for authorized warranty repairs we handle the LG claim and bill LG for the covered part.
Our same-day compressor replacement
- Diagnose — confirm it is the compressor / sealed system (not a fan, board, or thermistor)
- Recover the refrigerant safely to EPA-608 spec
- Install a genuine LG OEM linear compressor and a new filter-drier
- Pull a deep vacuum, leak-test, and recharge to factory spec
- Verify the fridge pulls down to temperature before we leave

Is your compressor still under warranty?
Text or call with the model and serial number (on the sticker inside the fridge) and we will tell you in minutes whether LG’s 10-year linear-compressor warranty covers your part — before we come out.
What’s wrong with my LG fridge?
Start from what you see. These are the patterns we meet most on LG refrigerators in the Bay Area.
| Fridge and freezer both warm | Usually the linear compressor or another sealed-system fault. The part may be covered by LG for 10 years. |
|---|---|
| Only the freezer is warm, fridge is fine | Usually a freezer fan, a defrost fault or ice packed on the evaporator — not the compressor. Usually one visit. |
| No ice, but the freezer is cold | The ice maker or the water valve. If the freezer is warm too, the ice maker is not the problem — the cooling is. |
| A code on the display | See the error-code table below: the code tells us where to look. |
LG refrigerator error codes
What the common LG codes point to. A code tells us where to look; the technician confirms the cause on site. Tell us the code when you call and we bring the likely part.
| FF (FF E, Er FF) | Freezer fan, usually iced in |
|---|---|
| rF (rF E, Er rF) | Fridge-section fan |
| IF (IF E; reads as 1F or F1) | Ice-compartment fan |
| CF (CF E, Er CF) | Condenser fan (back of the fridge) |
| dH (Er dH) | Defrost failed: heater, fuse, drain or board |
| IS (reads as 1S) | Ice-maker sensor |
| CO (CO E, Er CO) | Main board and display not communicating |
| gF | Water flow sensor or water pressure |
| CH (CH E, Er CH) | Refrigerant (sealed system), high side — likely a condenser leak |
| CL (CL E, Er CL) | Refrigerant (sealed system), low side — likely an evaporator leak. Not the lock |
| 22 / 33 | Compressor relay on LG’s list; the same digits also show in the board’s test mode after service |
| 67 | A door isn’t closing |
How LG’s refrigerator warranty works
- Years 1–5 from purchase: LG covers sealed-system parts and labor.
- Years 6–10: LG still covers the linear compressor part; labor is paid by you.
- It counts from the purchase date, not the build date — keep your receipt (a Costco or store receipt works).
- Covered repairs are authorized by LG per job, and the covered part is billed to LG.
How old is my LG?
Find the model and serial sticker inside the fridge — usually on the left wall or the door frame. On the serial number the first digit is the year and the next two are the month: 804… was built in April 2018. Warranty counts from your purchase date, so the receipt matters more than the build date.
What an LG refrigerator repair costs
- Diagnostic: $100, waived if you go ahead with the repair.
- If LG’s warranty covers the part, you typically pay labor only.
- We quote the repair before any work starts, so you decide with the full number in front of you.
- A 7–9-year-old LG is often worth fixing: with the compressor part covered for 10 years, the repair usually costs far less than a comparable new French-door fridge. We tell you honestly if it is not worth it.
Before the technician comes
- Clear access to the back of the fridge.
- Move frozen food to a cooler — on a sealed-system repair the freezer needs to be empty.
- Have a photo of the model and serial sticker, and your proof of purchase if you have it.

★★★★★
“They were the first to respond, came quickly, arranged for parts to be free through an LG warranty, and came back to install at a time that worked for us. Got the fridge up and running and followed up after.”
Common questions
Yes — we handle in-warranty LG sealed-system and linear-compressor repairs, authorized by LG per job and billed to LG. Text us a photo of the nameplate and your proof of purchase and we confirm coverage.
The diagnostic is $100 and is waived when you proceed. If your linear compressor is still under LG’s 10-year warranty, the compressor part is covered and you typically pay only labor — we confirm coverage from your model and serial first.
Most LG compressor and sealed-system repairs are done in a single same-day visit. We carry OEM linear compressors and recharge equipment on the truck.
Same-day visits are available across San Mateo and Santa Clara counties. Text a photo of the model/serial sticker and your address and we will schedule it.
