The short answer
On the Arctic Wind AUFW refrigerator line, a cabinet that is not cooling is worth working through in a set order: thermostat, sensor or control settings first, then a dust-blanketed condenser coil, or a condenser fan that has stopped, 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 you observe
- The cabinet is cold but not cold enough, and has been steady that way — A small constant error points at a setting or a sensor rather than at airflow.
- 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.
- 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, most likely first on the AUFW line
- Thermostat, sensor or control settings — Ranked first: a control that has been nudged, a sensor reading warm or a cabinet left in demo mode after a store display will hold the machine at the wrong temperature with nothing mechanically wrong at all, and it is the cheapest of these to rule out.
- A dust-blanketed condenser coil, or a condenser fan that has stopped — A dirty coil or a stopped condenser fan produces a cabinet that never quite reaches temperature, and both are visible from the back.
- A stalled defrost cycle icing up the evaporator — A stalled defrost cycle ices the evaporator over slowly, so the cabinet warms while everything else appears to work.
- Door seals, over-packing and blocked internal vents — Seals and loading are worth re-checking at the end too, because they make every other fault on this list look worse than it is.
- 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.
Check in this order, and why
- Read the setting, then measure the actual temperature with a glass of water and a thermometer — A refrigerator holds food safely at 40 °F (4 °C) or below and a freezer at 0 °F (−18 °C) or below. Done first because it separates the likeliest causes before any tool is needed.
- Unplug the unit and look at the condenser coil and fan at the back or underneath — Second: it confirms or dismisses what the first check suggested.
- Empty the freezer and look at the rear panel — Third, once the two checks above are clean.
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. 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.

When to call a technician
Call when the seals, the vents, the coil and a full defrost have all been done and the cabinet still will not hold temperature, because what is left is the sealed system. Call the same day if nothing at all is cold, so that the food question gets decided quickly.
