The short answer
On the AU family new noises often trace to ice and to things touching it rather than to a mechanical part wearing out. Cabinets that build frost develop noises as the ice grows into places it does not belong, and the noise appears and disappears with the frost.
What you observe on these models
- A hum or buzz that runs with the compressor — It starts and stops with the machine, which places it at the compressor end of the cabinet.
- A rattle that changes if you lean on the cabinet — That is the cabinet, the feet or a loose panel rather than anything inside the sealed system.
- A repeated click every few seconds with no steady run — A start device attempting and failing. Worth attention even while the cabinet is still cold.
- NEAR MISS - a loud noise together with softening contents — Noise plus lost temperature is a cooling fault first. Treat it on the cooling page and the noise usually explains itself.
Causes, most likely first on this family
- Ice contacting a fan, a shelf or the lid seal — First on this family. Frost grows where humid air enters, and once it reaches something that moves or closes, it produces a scraping or a creaking that was not there a month ago, and on a single-model family there is no configuration question to settle first.
- Contents shifting and baskets rubbing — Second, and the least mechanical explanation on the list. Frozen packs settling against a wall or a basket riding on ice make noises owners reasonably attribute to the machine.
- Cabinet, feet and panel fixings — Third. A cabinet that rocks or has a loose rear cover drums and buzzes, and it is worth clearing before anything is dismantled.
- Compressor, its mounts and the start device — Last. These are the genuine component noises, and on this family they are outnumbered by the three causes above.
Check in this order, and why this family dictates it
- Open the cabinet and look for ice where something moves or closes — Ice at the seal, at a basket runner or around a fan explains most of these without any tool.
- Empty and defrost the cabinet completely, then listen again — Second: a noise that has gone after a defrost was ice, and that is a seal problem rather than a mechanical one.
- Rock the cabinet and check the rear cover — Third, because it clears the structural noises before any part is suspected.
- Listen at the compressor for knock, grind or a repeating click — Last: those three findings are the ones that need a technician, and everything above is cheaper to rule out first.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Do not run the cabinet with its rear cover removed to chase a noise, do not wedge or pack anything against the compressor to quieten it, and never lever or bend the tubing at the back: a split line ends the cabinet and vents refrigerant into the room.

When to call a technician
Call when the compressor knocks or grinds through a run, when a click repeats every few seconds without the cabinet settling into a steady run, when there is a burning smell, or when the noise came with the contents starting to soften. This family is a single model, so the start device and mount kit can be identified before the visit.
