LG refrigerators
Three hundred and forty-seven of them are in LG's US catalog, which makes this the biggest part of what the badge sells and the biggest part of what we are called out for. LG is also the make that tells you most about itself when something goes wrong: the refrigerator carries a published code for the condenser fan, the freezer fan, the refrigerator fan, three separate sensors and the ice maker, and you can force it to show you the last one by holding two buttons. In a South Florida kitchen most of the calls are not the sealed system. They are ice, water, a fan that iced up behind the back wall, or a door that stopped sealing in air that is wet nine months of the year.

What goes wrong with it
Symptoms we are called out to on LG refrigerators
Each one covers the likely causes in the order they are worth checking, and what to do in five minutes before booking anything.
-
The lights are on and the food is warm Refrigerator not cooling
The most common call on this badge, and the first check is free. An LG refrigerator has a showroom mode that lights the whole panel, runs the fans and cools nothing at all, and it gets switched on at home by accident often enough that we ask about it on the phone before anything else.
- Demo mode looks exactly like a broken refrigerator and clears in ten seconds
- Three separate fan codes, and the usual cause of all three is ice rather than a dead motor
- The sealed system is last, and it is measured rather than assumed
-
One compartment is right and the other is not Fridge warm and freezer cold
The combination that rules more out than it rules in. On most LG cabinets one cooling system feeds both compartments and a damper divides the cold between them, so a freezer that is still hard proves the compressor, the gas and the condenser are all doing their job — and moves the whole question to how the cold is getting from one side to the other.
- A hard freezer proves the sealed system is fine, which removes the expensive answer
- Air, damper, or the fan feeding the fresh food side
- On a two-evaporator cabinet, the code prefix says which coil is involved
-
Water on the floor, or under the crisper Refrigerator leaking water
Water arrives from two places on this appliance and they are completely different repairs. Melt water that should have gone down a drain and did not, or supply water from the line that feeds the dispenser and the ice maker. Where the puddle is tells you which, and it is worth knowing before anybody is called.
- Under the crisper means the defrost drain, which is often a five-minute clear
- At the back or the toe kick means the supply line or the drain pan
- A leak that only appears after ice is made is the fill valve, not the drain
-
Soft packets, and water in the bottom basket Freezer not freezing
On this make the freezer is a compartment rather than a separate machine, which changes the diagnosis in a useful way: the compartment beside it is a live instrument. A freezer that is failing while the fresh food side holds is telling you something quite different from both of them drifting together, and LG's own codes carry that distinction in their prefix.
- The refrigerator compartment beside it is the most useful measurement you have
- FF, FS and dS are published and each names a different part
- A drawer that will not close on a packet is a real and common cause
-
A white wall behind the back panel Frost building up in the freezer
Frost inside a freezer is not a cosmetic problem and it does not stay a small one. A modern cabinet is supposed to melt its own coil clear every few hours; when it stops doing that, the ice grows across the airway until the compartment above it starts to fail. This is the slow failure that people live with for a month and then call about in a hurry.
- A frost-free cabinet with frost has a defrost problem, by definition
- dS is the sensor half of the circuit; the heater is measured rather than read
- Do not chip at it — the coil is aluminum and the tubing is thin
-
The bucket is empty and everything else looks fine Ice maker not making ice
The most common call on this badge after cooling itself, and the one where the useful question is not about the ice maker at all. Does the water dispenser still work? That single answer splits the problem in half before anybody opens anything, because ice and water share a supply and part company inside the door.
- Water working and ice not moves the whole question inside the compartment
- IF, IS and It are published — fan, sensor and motor
- A fill tube frozen at the mouth is common here and free to clear
What we do on it
Repairs we carry out on LG refrigerators
Starting figures for this equipment in South Florida. The exact cost is confirmed after an on-site diagnostic — and this is not the whole list of what can go wrong, so call if your problem is not here.
-
from $95 Diagnostic visit
One visit, one technician, one answer in writing. On this make the diagnostic starts with something most makes cannot offer: the appliance usually has something to say. LG publishes code lists for its refrigerators, dishwashers, washers, dryers and ranges, and on the machines with no display it publishes what the blinking lights mean instead. Reading that properly is half the job and it costs nothing to do.
- The model number and whatever the appliance is reporting, read before anything is opened
- Blinking-light patterns included, because LG documents them and that makes them codes
- Written findings and a from-price before any part is ordered
-
from $125 Appliance maintenance
The visit that stops the other visits. Most of what fails on an LG in this city fails because of something that could have been cleaned: a condenser packed with dust, a dishwasher filter nobody has taken out, a dryer duct that has been closing for three years. None of it is glamorous and all of it is cheaper than the repair it prevents.
- Condenser, filters, seals, drains and levels on whatever you have
- Written findings, so you know what is aging before it fails
- Priced on time rather than per appliance
-
from $145 Appliance installation
Delivery is not installation. A machine that has been put in place is level, connected, tested, and standing with the clearances its manufacturer specifies — and on LG's ventless laundry and its built-in cooking there are specifics that get missed often enough to be worth naming.
- Leveled and tested, not just connected and left
- Clearances checked, because a built-in with no vent path fails in August
- Gas connections leak-tested and documented
-
from $155 Refrigerator not cooling repair
The most common repair on this badge and the one where the order of work matters most. Air first, then defrost, then the sealed system — a sequence that goes from free to expensive and that anybody quoting a compressor over the phone has skipped two thirds of.
- Demo mode and blocked vents are ruled out before anything is opened
- LG publishes three separate fan codes and the usual cause of all three is ice
- The sealed system is measured with gauges, never assumed
-
from $175 Defrost system repair
The slow failure that takes three weeks to show and then takes the whole cabinet. A refrigerator melts its own evaporator clear every few hours; when that stops, ice grows across the airway until the compartment above it can no longer be fed. LG publishes dS for the sensor half of the circuit and the rest is measured.
- Heater, sensor and control — three parts, one circuit
- The cabinet is defrosted properly first, which is time before any part
- Frost on the back wall is this, not the fan and not the gas
-
from $165 Evaporator fan repair
LG puts a sensor on its fans, so a blocked or stopped blade is reported rather than left for you to work out from a warm compartment. Three of them are named separately — CF in the machine room, FF in the freezer, rF on the fresh food side — and in this climate the usual cause of all three is ice rather than a dead motor.
- Three fans, three codes, three different access routes
- Ice is the cause more often than the motor, and that changes the repair
- The compartment has to be emptied and often thawed first
-
from $125 Condenser cleaning service
The cheapest thing on this list and the one that prevents the most expensive. The condenser is the coil that throws the heat away, and in a coastal kitchen it fills with dust, hair and salt air until the compressor is working against a blanket. LG codes the fan over it as CF; nothing codes the coil itself, which is why it goes unnoticed for years.
- Coil, fan and machine room, properly rather than a brush at the front
- Nothing reports a dirty coil — it is found by looking
- It lowers the running temperature, the noise and the bill
-
from $155 Ice maker repair
LG's ice makers live inside the refrigerator — in the door, in the freezer, or as the second unit that makes round Craft Ice — and it publishes three codes for them: IF for the fan that carries cold, IS for the sensor that decides the cubes are frozen, and It for the motor that harvests them. Between them those three cover air, cold and mechanism.
- IF, IS and It: fan, sensor and motor, each named by the manufacturer
- A tray full of ice with an empty bucket is the mechanism; an empty dry tray is water
- The module comes out as an assembly
-
from $145 Ice fill tube and heater service
The small white tube that delivers water into the tray ends inside a compartment kept below freezing, and in this climate it grows a plug of ice at the mouth that stops the fill without ever showing a code. Clearing it is short. Replacing the heater that is supposed to stop it happening is not.
- The commonest no-ice cause that no code reports
- Clearing it is quick; the heater around it is the real repair
- Often paired with a door that is not sealing
-
from $115 Water dispenser and filter service
The cheapest refrigeration row on this site and the one most often mistaken for something larger. Between the mains and the glass there is a valve, a filter, a tank on some models, a line, and a dispenser switch — and any of them will produce no water, slow water, or a leak that gets blamed on the defrost drain.
- Filter, housing, tank, line and valve, in that order
- A cartridge a few millimeters proud weeps steadily and is missed for months
- Air in the line after a change is normal and clears itself
-
from $145 Door seal replacement
Nine wet months a year is hard on a gasket, and a cabinet fighting its own door runs constantly and still loses. The part is not expensive; the fitting is fussy, because a gasket that is not seated evenly all the way round is worse than the tired one it replaced.
- A paper test finds it in thirty seconds and most people never do one
- It is behind a great many cooling, frost and ice complaints
- Fitting evenly is the job — the part is the easy half
-
from $155 Temperature sensor replacement
LG publishes four separate sensor codes on its refrigerators — FS for the freezer, rS for the fresh food side, dS for the defrost coil and rT for the room — and they are not all in the same place. A cabinet that has lost one still cools; it simply cannot aim, which is why this arrives as a machine that swings rather than one that has stopped.
- Four sensors, four codes, four different locations
- A cabinet with a bad sensor will happily freeze the fresh food side
- Small part, contained job, and worth doing promptly
-
from $595 Sealed system repair
Real, uncommon, and last. It is the only refrigeration repair that needs gauges, recovery, brazing and a vacuum, and it is the only one where the number is large. On this make there is a second reason to be careful before it is quoted: LG's linear compressors carry a long parts warranty that follows the machine rather than the owner.
- Diagnosed with gauges, never from a symptom or a code
- The compressor warranty position is established before any figure is given
- Recovery, drier, vacuum and charge — the whole procedure or none of it
-
from $145 Refrigerator leak repair
Water arrives from two places on this appliance and they are entirely different repairs. Melt water that should have gone down a drain, or supply water from the line that feeds the dispenser and the ice maker. Where the puddle is decides which, and the diagnosis comes before the quote.
- Under the crisper is the defrost drain; at the back is the supply
- A cracked drain pan leaves a trail rather than a puddle
- A filter housing that was not seated is the cheapest cause and the most missed
-
from $185 InstaView door repair
The panel that lights when you knock on it is glass, a light, a sensor and a harness that runs through a hinge. It is LG's own, no other make on this fleet has it, and it fails in ways a plain door does not: a panel that stays dark, one that lights and will not go out, or a communication code because the wiring through the hinge has fatigued.
- A door panel with electronics in it, and wiring through a moving hinge
- CO — the board-to-display communication code — often starts here
- Glass, sensor, lamp and harness are four different repairs
-
from $285 Appliance control board repair
The board is the last thing suspected rather than the first, because supply problems imitate it perfectly: a long extension lead, a shared circuit with something heavy on it, or a socket with a poor neutral will all produce board errors on a machine that is otherwise healthy. A second board fails exactly the way the first one did.
- The supply is checked first, every time
- EE on a washer and F11 on a range are board-level codes
- A board replaced without finding what killed it is a repeat visit
-
from $115 Smart diagnosis and firmware service
LG builds diagnostics into these machines that most makes do not: a connected app, a stored history, and on many models an audible diagnosis the machine plays down a phone line. When that side stops working the appliance still washes and still cools — but you lose the reporting, and on this make the reporting is worth having.
- Connectivity, firmware and the app-side diagnosis
- The machine works without it; you lose the instrumentation
- Often a network problem rather than an appliance one

About LG refrigerators
Four cabinet layouts, and a compressor LG argues about
LG's US catalog carries 347 refrigerators. French door is the bulk of it, in three- and four-door forms; side-by-side, top freezer and bottom freezer fill in the rest, and InstaView — the panel that lights up when you knock on it — runs across the top of the range. The argument LG makes for itself is the compressor: a linear or inverter linear unit rather than a reciprocating one, sold on a long parts warranty. It is a real difference and it changes what a repair looks like, because a linear compressor failure is a sealed-system job with a warranty conversation attached rather than a straight swap.
What the codes actually cover
This is one of the best-documented refrigerators sold in this country. LG names the failure for the machine-room fan, the freezer fan, the refrigerator fan, the freezer sensor, the refrigerator sensor, the defrost sensor, the ambient sensor, the ice maker fan, the ice maker sensor, the ice maker motor and the water tank, each with its own two-letter code and its own published meaning. On a cabinet with two evaporators the prefix — Er, F or r — says which compartment is being reported. That is more than most makes publish, and it is why a first visit here starts with the code rather than with the toolbag.

Questions about LG refrigerators
It is running but it is not cold enough. Where does that usually end up?
Air before refrigerant, and on this make that is not a way of saying nothing. LG publishes three separate fan codes — CF for the condenser fan in the machine room, FF for the freezer fan and rF for the refrigerator fan — and its own explanation for each of them is a fan the machine has detected as blocked, with the compressor then overworking and the cabinet slowly losing ground. A freezer packed to the back wall does the same thing and shows no code at all. After air comes defrost, which reads as one compartment getting warmer over days while the other stays right, and which LG codes as dS when the sensor itself is the problem. The sealed system is real, it is last, and it is measured rather than guessed at.
How do I get it to show me the code?
Press and hold Freezer Temperature and Express Frz together for at least three seconds. LG documents this, and it matters after a power cut, because the display clears on its own and the failure does not. Write down exactly what you see, including the letter in front — LG uses E, r and Er as prefixes and on a two-evaporator cabinet the prefix is the part that says which side of the machine is being complained about.
Is the ten-year compressor warranty worth anything on a call like this?
Often, and it is worth checking before anybody quotes you. LG's linear compressors carry a long parts warranty and the paperwork follows the machine rather than the owner, so a cabinet bought used can still be covered. What the warranty does not cover is the labor, the gas or the drier, which is why a sealed-system quote on a covered machine still has a real number on it. We say which part of the bill the warranty takes before the work starts.
Does the humidity here actually change anything?
Yes, and it shows up in the same three places every summer. Door gaskets give up earlier, so the cabinet runs longer and ices its own evaporator. Defrost drains block sooner, and the water arrives under the crisper rather than on the floor where you would see it. And an ice maker in a house where the door opens twenty times an evening spends its life recovering. None of that is a failure in the machine. It is what this climate does to a machine that is working.
