Start here
The Arctic Wind ATMW refrigerator family covers five listings in the roster below, and on that platform the first split is whether both compartments are warm or only one. Of the things that stop a refrigerator cooling, the two most common cost a part that fits in a pocket and the least common costs more than many machines are worth. Frost on the freezer rear panel, a fan you cannot hear and a condenser packed with dust account for most of what a technician finds.
What an owner actually sees
- Both compartments are warm and the machine is running continuously — Either the air path is blocked at the source or the system is no longer moving heat.
- The compressor runs and runs but never satisfies — A long run is normal; a run that never ends is the machine chasing a setpoint it cannot reach, and it is the same fault seen from the other side.
- The condenser coil or the grille at the bottom is packed with dust — Heat has to leave the machine somewhere. A blanketed coil raises head pressure, runs the compressor hot and shows up first as a cabinet that has quietly lost a few degrees.
- NEAR MISS — the machine is silent and nothing is cold at all — No compressor sound, no fan, no light behaviour: that is a power, relay or control fault rather than the cooling path, and it is a different page from this one.
Causes, most likely first on the ATMW line
- Airflow blocked by frost on the evaporator — Ranked first on the ATMW line, because defrost systems stall long before they fail outright, so ice builds quietly over weeks while the cabinet gives up a degree at a time, and by the time an owner notices the warmth the frost sheet is already the whole story. The wildcard tails on this roster are finish and trim, not mechanism, so a difference in what you see on the outside is not a reason to expect a different cause inside.
- Condenser coil blanketed with dust, or the condenser fan stopped — Second on the ATMW line, because heat can only leave through that coil, so a felt of dust and pet hair works as insulation in exactly the place the machine needs bare metal.
- Cabinet packed so the rear air outlets are blocked — Third on the ATMW line, because it is an arrangement problem rather than a fault, it costs nothing to put right, and it produces a warm compartment on a machine where every part is working exactly as designed.
- Thermostat or temperature sensor reading wrongly — Fourth on the ATMW line, because a sensor that reads colder than the cabinet actually is will satisfy the control early and leave the compartment warm, which looks like weak cooling and is really a measurement fault.
- Defrost heater, sensor or control no longer completing the cycle — Last on the ATMW line, because it sits behind the frost it causes: the frost is the symptom you can see, and which of the three parts failed is the part of the diagnosis that needs a meter and the panel off.
Check in this order, and why
- Compare the two compartments before anything else — A hard-frozen freezer with a warm fresh-food side is an air-path fault. Both warm is a source fault.
- Clear the rear air outlets and rearrange the contents — Pull food back from the vents at the rear of both compartments and re-seat the drawers.
- Pull the machine out and look at the condenser — Dust on the coil and a condenser fan that is not turning are both visible from the back or through the lower grille, and both are owner-serviceable with the machine unplugged.
Safety first
Safety
Pull the plug before the evaporator cover or the lower grille comes off — a capacitor can hold a charge after the power is off, and the fan behind that cover starts without warning. Refrigerant work is licensed work. If tubing is cut, kinked or weeping oil, stop: oil outside the tubing means the system is open, and running the compressor after that point does further damage every hour.
Models in the ATMW family — The roster above is what this article generalizes over; a page written for a single model would go further than this one does. Model numbers come from the platform data and are reproduced unchanged.

When to call a technician
Call once the fan runs, the coil is clear, the seals hold and the cabinet is still warm, because what is left is the defrost circuit or the sealed system and both need a meter in the first case and a licence in the second. While you wait, move perishables to a cooler with ice and keep the doors shut. Every opening costs cold air the machine is currently unable to replace.
