The short answer
On the Arctic Wind ACFW 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 you observe
- 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 freezer is fine and only the ice maker has stopped — That is an ice production fault; the cooling system is doing its job.
Causes, most likely first on the ACFW line
- A dust-blanketed condenser coil, or a condenser fan that has stopped — Checked first here: 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.
- 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.
- 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.
Check in this order, and why
- 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.
- 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. While the cabinet is warm, treat the food as the priority: a refrigerator holds food safely at 40 °F (4 °C) or below, so move anything perishable into a cooler with ice before you start work rather than after.

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.
