The short answer
The AUFM 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. 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
- Vibration you can feel through the floor — The cabinet is transmitting into the structure rather than absorbing into its own feet.
- A buzz from the back of the cabinet that changes pitch — The condenser fan or its shroud has picked something up.
- A hum that rises and falls with the compressor — It begins when the cabinet starts a cooling run and ends when the run does.
- 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.
Causes, most likely first on the AUFM line
- Condenser fan or its shroud fouled — Ranked first on this roster: anything light that gets pulled into the condenser compartment stays there, and it makes contact with a blade long before it blocks any airflow.
- Loose shelf, basket, hinge or trim — Ranked second on this roster: baskets, dividers and lid or door hardware move fractionally with every cycle, and once one of them is loose it buzzes only at the frequency the compressor happens to be producing.
- Cabinet not level, or resonating against the floor — Ranked third on this roster: the feet are the only thing between a running compressor and the room, so a foot that is not carrying its share sends the vibration into the floor instead.
- 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 loose shelf, which moves up on the AUFM 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.
