This fault reads the same on every make, but it does not rank the same. On the AZM models it is usually an air damper stuck between the two compartments. This page covers a single model, so every unit in service is the same machine.
What this looks like from the front
- 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.
The ranking that matters here on the AZM line
- An air damper stuck between the two compartments — Ranked first here — it explains the split case — a freezer holding while the fresh-food side climbs — and not the case where both are warm.
- 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 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.
- A leak or restriction in the sealed system — Fourth here — it is the least likely of the list and the only one that is not an owner check.
- Body: With one model in scope there is no spread of builds to hedge against, so a design-inherent fault ranks above an age-related one and the list below says so plainly. Concretely, an air damper stuck between the two compartments outranks a door gasket here, and that is the difference worth reading for.
The order of checks, and the reason for it
- Compare the two compartments before anything else — One cold and one warm points at the damper; both warm points back up the list.
- Shut a sheet of paper in the door and pull it out — Do it at four points on each side.
- 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.
- 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: One model means one layout, so the order below is the order of the panels you would open, and there is no second build to hedge against. 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.
What to do before you touch it
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.

The line between a fix and a call
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.
