The short answer
The AU roster records a single model, so nothing on this page has to be hedged across variants, and it is the only entry on that roster, so the rating plate confirms your cabinet in a single step. A freezer in this roster that has started making an unfamiliar noise is far more often a moving part fouled or a cabinet resonating than a failing compressor. The noises that matter are the ones that change when you open the lid or press on a panel; the ones that do not change are usually the sealed system doing what it is supposed to do.
What you observe on these models
- A rattle you can stop by pressing on a panel — Press the side, the back and the lid or door in turn while the cabinet is running.
- A chirp or scrape from inside the cabinet — On models with a forced-air compartment this is a fan blade catching frost or a worn motor bushing.
- A click every few minutes with no cooling run following it — The start components are trying and failing to bring the compressor up.
- Gurgling or boiling after the cabinet stops — Refrigerant settling in the tubing once the compressor shuts down.
Causes, most likely first on the AU line
- Condenser fan or its shroud fouled — Ranked first on this roster: dust, packaging film and pet hair collect behind the cabinet and end up against the fan, and the result is a buzz or a rattle that comes and goes with the cooling run rather than a steady tone.
- Loose shelf, basket, hinge or trim — Ranked second on this roster: interior hardware is the one cause here you can confirm without tools, and it accounts for a large share of noise calls that turn out to need no part.
- Cabinet not level, or resonating against the floor — Ranked third on this roster: hard floors and flexing floors both amplify what the cabinet does normally, which is why the same machine sounds different in two rooms.
- A noise from inside the sealed system — Ranked last on this roster: a knock or a metallic rattle that comes from the compressor shell itself is the least likely outcome here and the only one that cannot be reached without opening a sealed circuit.
- Body: Where this ranking departs from the brand-generic order is loose shelf, which moves up on the AU line because this roster is a single cabinet rather than a line, so the order is what that one machine makes likely and not an average taken across several.
Check in this order, and why
- Pull the cabinet clear and look into the condenser compartment — With the cabinet unplugged, look for film, hair or a fallen object touching the fan blade or its shroud. This settles the most common cause with nothing more than a torch.
- Press and hold each panel, basket and hinge in turn — Work around the cabinet while it runs. Anything that goes quiet under your hand has been found.
- Rock the cabinet corner to corner and adjust the feet — Take the play out of every foot so all of them carry load. This costs minutes and removes the most misdiagnosed noise on the list.
- Look for oil film on the tubing at the back — Oil outside the tubing means the sealed circuit is open. Stop, and have it assessed before it runs any longer.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Condenser fins are sharp and the fan can restart without warning while power is connected, so never reach into the condenser compartment to feel for an obstruction. Leave the door or lid switch wired as it is: it cuts the interior fan for a reason, and defeating it puts your hand next to a blade that is live.

When to call a technician
Owner territory ends where a tool starts on these cabinets. Levelling, clearing the condenser compartment and finding a loose basket need no tool at all; anything behind a fastened panel, and anything involving the compressor or its mounts, needs a technician. Call straight away rather than working through the list if the cabinet is also failing to hold temperature, because then the noise is a secondary symptom.
