The short answer
On the Arctic Wind AUFSS freezer family a new noise is nearly always a fan that has picked something up or a cabinet that has lost its footing, not a compressor on its way out. The roster here is a single listing, AUFSS210ETH-LK. A dedicated freezer has fewer moving parts than a refrigerator, which makes the diagnosis shorter and the list of suspects genuinely small.
What you observe
- A buzz or rattle that stops when the door is opened — The internal fan is switched by the door on this cabinet, so the door itself is a free diagnostic and it settles the biggest fork on the page.
- A scraping that changes pitch with the fan — Ice built against a blade tip. The pitch tracks fan speed because the blade is what is hitting the ice.
- A chirp or squeal that has built up over weeks — A dry bearing announces itself gradually and does not respond to opening the door.
- NEAR MISS - loud hum with the cabinet warming — That is a cooling fault and belongs on the cooling page for this family, not here.
What it usually turns out to be
- Ice or a package contacting the fan blade — First on this roster. The fan sits inside the cold compartment, so anything that frosts or shifts ends up in the blade path. The tell is a noise that stops the instant the door is opened. Nothing in the AUFSS model spine separates its listings on this point.
- Cabinet not level or standing on an uneven floor — Worth checking before anything is opened: press each corner in turn and listen again. Across the AUFSS listings this is one finding rather than several.
- Fan bearing wear — Ranked mid-list: a real failure rather than an obstruction, so it does not clear itself, but it usually arrives after the obstruction causes have been ruled out. Confirm it against AUFSS210ETH-LK, or whichever number is on your own rating plate.
- Debris in the machine compartment — Common where the unit lives in a garage or a workshop, which is exactly where dedicated freezers tend to be sited.
- Hardened compressor mountings — The rubber isolators harden with age and stop absorbing a vibration that was always present. Nothing has failed.
- Compressor or sealed-system fault — Ranked last because it is both least likely and most expensive, which is the combination that punishes a guess.
- Body: Ranked by finding frequency, free checks first. The compressor sits last because it is both the least likely cause of a new noise and the only entry that is not owner-diagnosable.
The order to work in
- Open the door and listen — The internal fan is switched by the door. If the noise stops, it is compartment-side and you have halved the problem for free.
- Note whether the noise is constant or in bursts — Constant points at a bearing; bursts at the start of a run point at an obstruction.
- Look at how packages are stacked against the rear wall — A box leaning on the fan grille does exactly what ice does, and it is free to correct.
- Body: Work down this list rather than across it. The door test and the levelling check cost nothing and between them they resolve most noise calls on a dedicated freezer.
Before you open anything
Safety
Isolate the unit first - unplug it or switch off its breaker - and remember a capacitor can hold a charge after the power is off. Evaporator fins behind the rear panel are sharp, so wear gloves, and never chip at ice with a screwdriver: a punctured coil turns a fan job into a sealed-system job.

Where the owner line is
The line on this roster is the rear panel. In front of it: levelling, stacking, the door test. Behind it: the fan, the coil and the defrost hardware, all of which need the cabinet emptied. Call straight away for a burning smell or for oil anywhere in the machine compartment.
