The short answer for Artt ATUF
The Artt ATUF family answers this differently from the brand as a whole: here contact with a wall, a pipe or a neighbouring cabinet ranks ahead of the compressor or its start components, because of how these models are built and how they are reached. The first checks cost nothing, and three of the four causes listed here can be settled without a meter.
What you observe on these models
- A drumming that seems to come from the whole cabinet — A cabinet rocking on an uneven floor turns a normal hum into something that fills the room.
- Ticking from the shell as the cabinet cools or warms — Expansion noise, and normal on a cabinet with a shell condenser.
- A new noise that started after the cabinet was moved
- NEAR MISS — noise with contents that are also softening — Noise plus lost cooling belongs on the cooling page; here the noise would be a symptom, not the fault.
Causes, most likely first on Artt ATUF
- Contact with a wall, a pipe or a neighbouring cabinet — A shell that touches a wall turns the whole wall into a soundboard, and a tube touching a pipe behind carries the noise through the building. It sits at this point because the noise is loudest in the next room rather than at the cabinet, which is a signature nothing else produces.
- Levelling and floor contact — It earns this place because freezers live on rough, uneven, often sloping floors, which makes this far more common here than on a kitchen appliance.
- Compressor mounts and tubing contact — Placed at this point because the signature is precise — a knock at start and stop and silence in between — and it matches nothing else here.
- The compressor or its start components — A hard metallic knock under load, or a buzz that ends in a click every few minutes on a cabinet that is trying to start and failing. It is here because a chattering start relay gives a repeating buzz-click, which is a cheap part rather than a failed compressor — but still a technician job.
Check in this order, and why
- Pull the cabinet forward a hand-span and listen again — A noise that halves when the cabinet comes off the wall has been found without a tool.
- Push each top corner in turn and watch for movement — Any rock at all is worth correcting first; it explains more noise complaints than every component on this list combined.
- Why this order and not another — It follows the ranking, not a generic checklist: on Artt ATUF the first check separates contact with a wall from levelling and floor contact, and access decides the rest — what this family puts behind which panel is why the cheap check comes first.
Power off first, and what not to defeat
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. On a cold cabinet the parts that bite are behind the lower rear access panel, where the start relay and the run capacitor live, and behind the interior rear panel, where a defrost heater sits in the airflow.

When to call a technician
The boundary is the rear panel and the interior panel. Levelling, clearance and the fan area outside are owner work with the cord out; a motor behind the interior liner and anything bolted to the compressor are not. It is also a call if the noise has stayed after every free check, because what is left needs a meter.
