In short
On the Arctic Wind AUF refrigerator line, a cabinet that is not cooling is worth working through in a set order: a dust-blanketed condenser coil, or a condenser fan that has stopped first, then door seals, over-packing and blocked internal vents, and only after those does the sealed system enter the picture. That order is written for a line spanning several cabinet sizes and sequenced for how these models are put together, which is where it departs from the brand-generic article.
What an owner actually sees
- The compressor runs almost continuously and the back of the cabinet is very hot — Heat with nowhere to go is the signature of a blocked coil or a fan that has stopped.
- The fresh-food side is warm while the freezer is still cold — A split like that is nearly always air movement between the compartments rather than cooling itself.
- NEAR MISS — the cabinet is cold but there is water inside it — Water with normal temperatures is a drain fault, not a cooling fault, and it has its own page.
Causes in the order they are worth suspecting on the AUF line
- A dust-blanketed condenser coil, or a condenser fan that has stopped — Ranked first: a refrigerator cools by dumping heat off the condenser coil, and a coil under a blanket of dust cannot do it, so the compressor runs and runs while the cabinet slowly warms — this is the single most common repairable cause on cabinets more than a couple of years old.
- Door seals, over-packing and blocked internal vents — Seals and airflow are checked early because they cost nothing and they produce the same symptom as an expensive fault.
- Thermostat, sensor or control settings — A control or sensor fault is the remaining explanation when everything mechanical checks out and the error is small but constant.
- Sealed system, compressor or start components — Last here, and the only cause on this list that is not owner work — a sealed-system or compressor fault means the machine cannot make cold at all, and refrigerant work is licensed work with tools that are not owner tools.
What to check first, second and third
- Unplug the unit and look at the condenser coil and fan at the back or underneath — Dust thick enough to hide the fins, or a fan that was not turning when the compressor ran, is your answer. Done first because it separates the likeliest causes before any tool is needed.
- Close the door on a sheet of paper and pull — Second: it confirms or dismisses what the first check suggested.
- Read the setting, then measure the actual temperature with a glass of water and a thermometer — Third, once the two checks above are clean.
Before you start work
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Never chip ice off an evaporator with a screwdriver or a knife: the tubing behind it is thin-walled and a puncture turns a defrost repair into a sealed-system repair. Refrigerant work is licensed work, so leave the pipework alone entirely.

Where owner work ends
Call once the owner checks are clean, and immediately if you can smell burning or see oil under the compressor — oil outside the tubing means the system is open and every hour it runs after that costs more to put right.
