The short answer
On the Arctic Wind AUFW freezer a slow drift upwards in temperature is a different fault from a sudden stop. The drift is nearly always load, seal or heat rejection; the stop is electrical. Establishing which one you have takes a day of watching and saves a wasted visit.
What you see on the AUFW line
- Packages at the top are soft while the bottom is hard — An air-circulation fault in an upright rather than a loss of cooling.
- The outside of the cabinet is warm to the touch at the sides — Normal on many cabinets, where the condenser runs in the skin; hot and furred at the back is not.
- Contents are soft rather than hard frozen — Ice cream is the informal test and it gives the answer before a thermometer does.
- NEAR MISS - the cabinet is silent and everything has thawed — That is a power or control fault, not a capacity one, and it belongs on a different page.
Ranked for the AUFW line
- Lid or door not sealing, or left ajar — Most likely here: It is also why the cabinet frosts heavily at the same time: the water in that warm air has to go somewhere, and it goes onto the coldest surface. The trailing letters of this family stem are Arctic Wind's finish code, and this is the white line: the mechanicals are shared with the sibling finish lines, so what genuinely separates this page from them is the door panel and what that panel weighs. A white panel on this line shows nothing, so owners here report the load and the inside of the machine long before they report anything about the door.
- Overloaded, or a large warm load put in at once — Second: Packing the cabinet so tightly that air cannot circulate has the same effect for much longer, particularly in an upright with a rear air path.
- Sealed-system fault or a failing compressor — Third: Refrigerant is not consumed, so a low charge means the circuit is open and repairing it is licensed work with equipment no household owns.
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 - Recall what went in during the last day or two, and how full the cabinet is — A recent warm load or a cabinet packed to the walls explains the drift without any part being at fault.
- 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
Call if the behaviour changes from day to day with no change from you - that points at the control side rather than the air path - and call if a full defrost bought only a few days of normal behaviour, because a frost-free cabinet that re-ices that fast has a defrost-circuit fault rather than a load problem.
