The short answer
The Avanti URBCD models covered here are undercounter beverage cabinets, and that construction decides which noises they make: a shallow glass-door cabinet that breathes entirely through the grille at the base of the door, with the compressor, the condenser and the fan crowded into one bay behind that grille. 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 noise that disappears the moment the door opens — That is inside the cabinet.
- A rattle that changes when you press on the cabinet — A line or a panel in contact with the shell.
- NEAR MISS — a loud click and then nothing cools — A start-relay fault, not a noise fault.
Causes, most likely first on URBCD
- The circulation fan inside the cabinet — A circulation fan clipping ice or running on a worn bearing gives a chirp, a warble or a scrape that changes when the door is opened, because the door switch cuts the fan. Opening the door cuts this fan on most cabinets, so a noise that stops the instant the door opens is this fan and nothing else. Ranked first here rather than further down, because a dual-zone beverage cabinet gives this cause more opportunities than any other on the list.
- 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.
- Ice contacting a fan or a panel — Ice growing where it should not be eventually reaches a moving part, and the noise arrives long after the ice did.
- Normal thermal ticking and flow noise — Refrigerant moving through a small circuit gurgles, and plastic liners tick as they change temperature. Both are normal and both get reported. 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.
- Press firmly on the cabinet sides and top — If the noise changes or stops, it is panel or tubing contact rather than a failing part — and that is a fix rather than a repair.
- Check the machine bay: kneel at the grille with the unit running and establish whether air is moving through it at all — Nothing is reached from the back while the unit is in its slot: it comes forward onto the floor first, and the grille at the base comes off before anything else does. Look for debris at the fan blade before assuming a bearing.
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. Before ordering anything, match the plate against the URBCD variant table above. The family is a dual-zone beverage cabinet, and parts that look alike across a brand's other lines often do not fit it.
