What this usually is
This fault reads the same on every make, but it does not rank the same. On the ATF models it is usually a defrost cycle that stops completing. This line runs to enough models that the units in service span a wide range of ages, so the parts that wear sit ahead of the parts that fail from a design weakness.
What the owner actually sees
- The cabinet is warm but the unit is clearly running — The compressor hum is there; the air inside is not cold.
- Frost builds as a sheet on the back wall of the freezer — Not the usual light dusting — a solid skin you can knock with a knuckle.
- Ice cream has gone soft but frozen food is still solid — A freezer a few degrees warm reads exactly like this before anything thaws.
- Condensation or a damp smell inside the fresh-food compartment — Warm air is reaching the cabinet, and it carries moisture with it.
- NEAR MISS — the cabinet is cold but water is pooling under the crisper — That is a drain fault, not a cooling fault, and it is covered on the leak page for this appliance.
What it usually turns out to be, in order on the ATF line
- A defrost cycle that stops completing — Ranked first here — it produces exactly this complaint — a running unit and a warm cabinet — while every other symptom stays normal for weeks.
- A compressor start relay or overload that has given up — Second here — it usually announces itself with a repeated click rather than with a quietly warming cabinet.
- A temperature sensor reporting the wrong reading — Third here — it is a plausible cause of a cabinet that never calls for cooling, but it is not the first thing to reach for.
- Body: A line this wide puts both old and recent units in front of you, and the ranking below favours the causes that come with age over the ones that come with a build. Concretely, a compressor start relay or overload outranks a temperature sensor reporting the wrong reading here, and that is the difference worth reading for.
What to look at first, second, third
- Empty the freezer, leave the door open and let the cabinet stand warm overnight — If cold returns afterwards and then fades again over days, the defrost system is the cause and nothing else needs testing.
- Listen at the compressor for a click every few minutes with no run that follows — A click-and-silence pattern is the start circuit; a steady hum is not.
- Watch whether the compressor cycles at all over an hour — A compressor that never starts, in a cabinet that is clearly warm, points at what is telling it the temperature.
- Body: Across a line this wide the access varies with the generation, so the order starts with checks that need no panel off at all, and only then moves to the ones that do. Work them in order: each one clears the cause it sits beside, and the next is only worth doing once the one before it is clean.
Switch it off first
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Leave the door switch wired as it is, and never run the cabinet with a panel off to watch it work.

Where owner work stops
Call once the owner checks above come back clean, and call at once if the fault is on the sealed system — refrigerant work is licensed work and the tools for it are not owner tools. Oil at the compressor, or a burning smell from the back of the cabinet, is a stop-now condition: every hour it runs after that costs more to put right.
