The short answer
The Avanti WC models covered here are wine cabinets, and that construction decides which noises they make: a narrow glass-door cabinet holding a still, tightly banded temperature over racked bottles, cooled either by a small compressor circuit or by a thermoelectric module depending on the model. Work from when the noise occurs to where it must be coming from, and you will usually name the part without removing a panel.
What you observe on these models
- A hum or buzz that starts and stops with the cooling — Machine-bay noise.
- A constant whine or whirr with no cycle to it — On a wine cabinet a sound with no cycle belongs to something that never stops, which narrows it immediately.
- Gurgling, ticking or a sigh after the machine stops — Refrigerant settling and plastic contracting.
- NEAR MISS — a loud click and then nothing cools — A start-relay fault, not a noise fault.
Causes, most likely first on WC
- The condenser fan in the machine bay — A fan blade that has picked up debris, or a bearing that has dried out, produces a rattle or a whine that starts and stops exactly with the compressor. On a compressor model the bay fan is the only fan; on a thermoelectric model it is one of a pair and they run constantly. It leads the list on Avanti WC because these are wine cabinets — a wine cabinet concentrates this fault in a way a full-size machine does not.
- The compressor and its mounts — A compressor sitting on tired rubber mounts transmits its own running note into the cabinet, which amplifies it. The sound is steady, low and present only while the circuit runs.
- Tubing or a wiring loom touching the cabinet — A line that has drifted into contact with the shell turns a normal vibration into a buzz. It is the most common cause of a noise that appears suddenly after the machine has been moved.
- Levelling and what the cabinet stands on — A cabinet rocking on one foot, or standing on a floor that flexes, will hum at a volume the same machine never reaches when it is sitting flat and firm. A loaded wine cabinet is heavy and will settle after it is filled, so it can go out of level without being touched. Last on this list, and the item that every cause above it can imitate exactly.
Check in this order, and why that order
- Time the noise against the cooling cycle — Stand by the cabinet for one full cycle. Whether the sound starts with the compressor, stops with it or ignores it entirely eliminates two thirds of the list before anything is touched.
- Open the door while the noise is happening — The interior fan stops when the door opens on most cabinets. A noise that survives the door being open is not inside the cabinet.
- Check the machine bay: establish which cooling type you have — a compressor cycles audibly, a thermoelectric module runs a constant fan and never thumps — The racks come out first, then the interior rear panel or the base plinth; on a built-in the cabinet must be drawn out of its opening before any panel is touched. Look for debris at the fan blade before assuming a bearing.
- Rock the cabinet corner to corner — A unit that moves on its feet is amplifying the machine into the floor. Level it and re-listen before pursuing anything mechanical.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel or reaching into the machine bay. A capacitor can hold a charge after the power is off, and a condenser fan will start without warning while the door is shut.

When to call a technician
Call when the noise is mechanical and inside the sealed part of the machine — a compressor that knocks under load, or a rising scrape that arrives with a cooling complaint. Call sooner if the noise is accompanied by a loss of cooling, because together they mean a part is failing rather than resonating. Check the plate before acting on any of this. WC is a wine cabinet, and the ranking above is written for that construction rather than for the brand as a whole.
