Symptom
LG 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.

Four ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
The fresh food fan
On cabinets that cool each side separately, the refrigerator has a fan of its own and rF is the code for it.
Evaporator fan repair from $165 -
A damper stuck closed
The flap that meters cold from the freezer into the fridge. Mechanical, cheap, and invisible from outside.
Temperature sensor replacement from $155 -
An evaporator partly sealed in ice
Enough frost to block the duct and not enough to stop the freezer. The classic slow defrost failure.
Defrost system repair from $175 -
Vents buried under food
The cheapest cause on the list and a real one. Cold cannot get past a stack of containers pushed to the back wall.

-
01
Measure both, do not judge by hand
A thermometer in each compartment for an hour. 'Cold' and 'not cold' are not numbers and this problem is about the gap between two numbers.
-
02
Feel for air at the fresh food vents
Hold a strip of tissue to the vent in the back wall. If it does not lift, nothing is arriving and that is the finding.
-
03
Clear the back wall and wait a day
Move everything six inches off the back of both compartments and give it twenty-four hours before deciding anything.
-
04
Read the code prefix
On a two-evaporator cabinet, F and r in front of the same code mean different coils. Write down exactly what is shown.
How it shows up
What people describe when they call
A shortcut
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem before anybody opens anything, which is why it is worth photographing before it clears.

About LG fridge warm and freezer cold
What the freezer is telling you
Do not skip past the good news. If the freezer is holding at or below 0°F, the compressor is running, the refrigerant is where it should be and the condenser is shedding heat — which rules out every expensive repair on the list before anybody opens a toolbag. What is left is the path the cold takes into the fresh food compartment: a damper, a duct, a fan, or an evaporator that has iced enough to block the air but not enough to stop the freezer.
What it usually means, by the kind of LG appliance
LG sells one appliance in several forms — five shapes of washer, three kinds of dryer, four fuels of range — and the same behavior points at different things on each of them. A built-in side-by-side and an integrated column are not the same service situation, and a dual-fuel range and an induction range fail in different halves.
- French door — The damper is usually in the back wall of the fresh food compartment behind a cover. A damper stuck shut gives exactly this and nothing else.
- Side-by-side — The longest air path of any layout, so this is the cabinet where a partly iced evaporator shows as a warm fridge first and a soft freezer much later.
- Bottom freezer — Look for frost around the vents at the top of the freezer drawer — that is where the air has to leave from to reach the compartment above.
One system, two compartments, one flap
Most LG refrigerators make cold in one place and divide it. The evaporator sits behind the back wall of the freezer, a fan moves air across it, and a damper — a motorized flap — meters how much of that air goes up into the fresh food compartment. That design is why this symptom is so common and why it is so often cheap: there are three or four things in the path and none of them is the compressor.
The version that is not cheap
An evaporator that has been slowly icing for a month will block the duct long before it stops the freezer, so a fresh food compartment that is drifting warm can be the first visible sign of a defrost circuit that stopped working weeks ago. The tell is frost you can see through the freezer vents and a freezer that has started running noticeably longer. That one is a real repair, and leaving it does not make it smaller.

Before you book
Questions about LG fridge warm and freezer cold
Can I just turn the fridge temperature down?
It rarely helps and it often makes things worse. If the cold is not arriving, asking for more of it just runs the freezer colder and freezes whatever is nearest the vent in the fresh food side. You end up with frozen lettuce and warm milk in the same compartment.
The freezer is fine but ice production has dropped too.
That points back at air rather than at the ice maker. The ice maker needs cold delivered to it as much as the fresh food side does, and on the door-mounted ice makers LG gives that its own fan and its own code, IF.
