The short answer
The models here are one machine in several finishes rather than several machines, so the design-inherent causes rank first and the installation causes fall back. That is why, on the AZC models, this complaint comes back to an evaporator fan that has stopped turning before anything else — and why the order below departs from the brand-generic one.
What you observe
- 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.
- The compressor never seems to stop — It runs and runs without reaching temperature, which is the same fault seen from the other side.
- 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.
Causes, most likely first on the AZC line
- An evaporator fan that has stopped turning — Ranked first here — it is a moving part under frost and it produces the same warm cabinet from a different component.
- A door gasket no longer pulling the door shut — Second here — it degrades slowly and the owner adapts to it long before noticing the cabinet is warm.
- A compressor start relay or overload that has given up — Third here — it usually announces itself with a repeated click rather than with a quietly warming cabinet.
- A cabinet standing somewhere it cannot shed heat — Fourth here — it is free to correct and it makes every other cause worse.
- Body: These are finish variants of a single build, so a fault found on one of them will be found on the rest, and the order reflects that rather than hedging. The build does not reorder this particular set of causes, so what you have below is the general order, stated for these models.
Check in this order, and why
- Open the freezer door, hold the door switch in and listen for the fan — A fan you cannot hear with the switch held in separates this cause from the other likely one before any tool comes out.
- Shut a sheet of paper in the door and pull it out — Do it at four points on each side.
- 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.
- 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.
- Body: These are finish variants of one machine, so access is identical across the line and the order below is purely about likelihood rather than about what is easiest to reach. The checks below are in the same order as the causes above them, so a clean result sends you one step further down rather than back to the top.
Before you open anything
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.
