The short answer
When the Arctic Wind AUFSS freezer will not freeze but is plainly running, the cold is still being made. The question is where it is going, and a tired gasket, a coil under a blanket of dust or a lid left ajar answer it far more often than a sealed-system fault does.
What you see on the AUFSS line
- Heavy frost on the walls and around the door — Warm moist air is getting in; the frost is where its water ends up.
- The cabinet holds overnight and drifts through the day — A heat-rejection problem rather than a refrigeration one.
- Packages at the top are soft while the bottom is hard — An air-circulation fault in an upright rather than a loss of cooling.
- NEAR MISS - water on the floor with the contents still frozen — That is a drainage fault; see the water-leak page instead.
Ranked for the AUFSS line
- Lid or door not sealing, or left ajar — Most likely here: Gasket rubber takes a set where it has been folded or frozen into place, and a gap you cannot see is one that never stops working against you. This is the stainless-panel line of the family; its finish siblings carry the same machine behind a different door, which matters here only where the door itself is part of the fault. The stainless door on this line is the heaviest panel the family is built with, which loads its hinges and its seal harder than the painted-panel siblings do.
- Condenser coil blanketed, or no clearance around the cabinet — Second: Heat leaves the machine at the condenser, and a felt of dust across it - or a cabinet jammed into an alcove - means the heat has nowhere to go.
- Sealed-system fault or a failing compressor — Third: It is the least common cause on this list and the only one that ends the owner's involvement, which is why it is checked last.
Check in this order, and why
- First - Run a sheet of paper round the seal at several points and pull — Drag everywhere is a good seal; a section that slides free is where the warm air is getting in. That is the order the roster on this page dictates, not a generic sequence.
- Second - Feel the coil for heat and look for dust; check the clearance behind and above — Hot and clean with air all round is healthy; hot and furred, or hot in a tight alcove, is your answer.
- Third - Compare how warm the compressor is against how warm the condenser is — A hot compressor with a cold condenser is the sealed-system signature and the point at which the checks stop.
Before you open anything
Safety
Power off at the plug or the breaker first. A loaded chest freezer is extremely heavy and should never be moved loaded, or moved alone; empty it into a cooler before it is pulled out for access to the coil. The tubing at the back of a unit that has just run is hot.

When to call a technician
The line is the panel and the plug: what you can see, seal, clear or unload is yours; anything read with a meter is not. Call without delay if the cabinet is losing a food load, since replacing that load usually costs more than the visit does, and a freezer that cannot hold safely should not be relied on for another week.
