Start here
Start with a condenser coil blanketed in dust and lint: on the AZB models it accounts for more of this complaint than the rest of the list put together. 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.
What this looks like from the front
- 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. A reader who sees this should leave for that one.
The ranking that matters here on the AZB line
- A condenser coil blanketed in dust and lint — Ranked first here — it costs nothing to rule out and it is the cause most often found on a cabinet nobody has pulled out in years.
- 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 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. Here the posture changes no positions — the causes on this page are far enough apart in likelihood that nothing moves.
The order of checks, and the reason for it
- Pull the cabinet out and look at the coil at the back or behind the toe grille — A grey felt across the fins is the answer; a coil you can see the metal of is not.
- Shut a sheet of paper in the door and pull it out — Do it at four points on each side. Anywhere the paper slides out with no drag is a gap the gasket is not closing.
- 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. Every check pairs with the cause at the same position, which is what makes a negative result useful rather than merely disappointing.
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. Leave the door switch wired as it is, and never run the cabinet with a panel off to watch it work.

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. Only the first checks above are owner work; the rest need the appliance opened.
