Start here
The Arctic Wind AUFSS refrigerator family covers a single listing in the roster below, and on that platform a cabinet that runs without getting cold is usually a delivery problem rather than a sealed-system 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 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.
- A door that does not pull itself shut from half open — A seal that has taken a set, or a cabinet leaning back too little, leaves a gap small enough to see past and large enough to run the machine continuously.
- NEAR MISS — the freezer is too cold and the fridge is too warm — That pairing usually means the damper or the air split between compartments rather than a cooling failure, and it is worth ruling in before anything else is suspected.
Causes, most likely first on the AUFSS line
- Airflow blocked by frost on the evaporator — Ranked first here, because the coil ices in normal use and depends on a cycle running properly to clear it, so a cycle that is merely late rather than absent will close the air path over weeks without any warning. Two listings on this label differ only by a build tail, so the first question on any fault that tracks with the door or the plumbing is which of the two is in front of you.
- Thermostat or temperature sensor reading wrongly — Second here, 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.
- Door seal or door alignment letting warm air in continuously — Third here: it is the cheapest cause to rule out and the most under-diagnosed one, because a gap that never shows itself when you are looking at the machine is open for every hour you are not.
- Defrost heater, sensor or control no longer completing the cycle — Last here, 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.
- Look at the freezer rear cover for frost at its edges — Ice creeping out around the cover is the visible end of a coil that has iced over.
- 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.
Before any panel comes off
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. A refrigerator is top-heavy with its doors open and it rolls unpredictably on a hard floor, so empty the doors and walk it out with a second pair of hands. Hands stay out of the machine compartment while it is plugged in, because the lower fan starts whenever the compressor calls and there is no interlock on it..
Models in the AUFSS family — Written for the whole roster above rather than for one listing; where a page exists for one of these models it goes further than this one. Model numbers come from the platform data and are reproduced unchanged.

Where the owner side ends
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. A machine that runs continuously without reaching temperature works its compressor far harder than normal, so a cheap fault left alone for a month can become an expensive one.
