The short answer
On the A models this complaint is most often a defrost cycle that stops completing rather than anything deeper. This line is a close pair of models rather than a spread, so the build is effectively uniform and the seal-and-fit causes come forward. The order below is settled by how this line is built, not by what is true of the brand as a whole.
What you observe
- 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.
- The freezer still holds while the fresh-food side climbs — A split like this narrows the list sharply, because it points at airflow between compartments rather than at cooling itself.
- 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 unit is silent and nothing is cold — That is a no-power or start-circuit fault, and it belongs on a different page.
Causes, most likely first on the A 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 cabinet standing somewhere it cannot shed heat — Second here — it is free to correct and it makes every other cause worse.
- A leak or restriction in the sealed system — Third here — it is the least likely of the list and the only one that is not an owner check.
- Body: Two closely related models means what holds for one holds for the other, which is why the order below is stated without a hedge. No cause changes place against a ranking that ignored the build, which is itself the finding: nothing about this line pulls one of them forward.
Check in this order, and why
- 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.
- Look at what is around and above the cabinet — Against a radiator, boxed into a cupboard, or with the top packed to the ceiling — all three hold heat against the condenser.
- Leave this one to a technician — It is confirmed with gauges on a system that must then be recovered and recharged, which is licensed work.
- Body: Two closely related models share a layout, so a check that works on one works on the other and the order below does not change between them. Each check answers the cause above it, in the same order, so a clean result moves you down the list rather than sideways.

Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Do not chip ice off an evaporator with anything metal: the tubing behind it is thin-walled, and a puncture turns a cheap repair into a sealed-system job.

When to call a technician
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.
