The short answer
Every model in the ARU roster shares one capacity core and differs only in finish or trim, so the cabinet behind them is the same machine throughout, and its entries differ only in the trailing finish position. An unfamiliar noise here is a locating problem before it is a repair problem. On these cabinets the same complaint is produced by a fouled fan, by hardened compressor mounts and by a cabinet sitting unevenly, and the three are told apart by what makes the noise stop rather than by what the noise sounds like.
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 ARU line
- Cabinet not level, or resonating against the floor — Ranked first 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.
- Condenser fan or its shroud fouled — Ranked second 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.
- Evaporator fan catching frost or a worn fan motor — Ranked third on this roster: a fan motor that has worn its bushings makes a noise that rises with the run and disappears the instant the door switch cuts it, which is what separates it from everything else on this list.
- A noise from inside the sealed system — Ranked last on this roster: oil anywhere on the tubing alongside the noise moves this from unlikely to urgent, because it means the circuit is already open.
- Body: Where this ranking departs from the brand-generic order is cabinet not level, which moves up on the ARU line because every cabinet in this roster is mechanically the same, so what genuinely varies across it is where each one has been installed.
Check in this order, and why
- 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.
- 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.
- Open the door and listen for the noise to stop — The door switch cuts the interior fan. A noise that dies within a second of opening, and returns when you press the switch, is the interior fan.
- 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.
