The short answer
The Avanti WBV models this page covers share one construction and therefore one failure pattern: 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. When one of these will not hold temperature, the cause is usually upstream of the sealed system, and the check that separates the cheap causes from the expensive one takes minutes rather than a service call.
What you observe on these models
- The cabinet is warm and the machine is plainly running — A unit that is working and never arriving is the presentation this page is about, and it is not the same fault as a cabinet that is silent.
- It runs continuously and never settles — On a wine cabinet a cycle that never ends means the machine has lost either its heat path or its air path — it has not lost its will to cool.
- One part of the interior is right and another is not — A temperature that varies across the cabinet is an airflow report.
- NEAR MISS — the cabinet is silent and nothing is cold — That is a power, start-relay or control fault rather than a cooling fault, and it belongs on a different page.
Causes, most likely first on WBV
- The set point, the sensor or the control board — A sensor reading the wrong temperature, or a set point someone changed, produces a machine that is behaving correctly against the wrong target. A narrow band means a small set-point error reads as a large fault, and the display is at finger height. Ranked first here rather than further down, because a divided wine and beverage cabinet gives this cause more opportunities than any other on the list.
- The door and its seal — A glass or gasketed door that no longer pulls up tight lets room air in continuously, and the machine answers by running without ever arriving.
- How the cabinet is loaded — A cabinet packed to the vents, or loaded warm in one go, reports as a cooling failure for days before it is one.
- A dirty or obstructed condenser — The condenser is where the heat leaves. Once it is blanketed in dust or fed its own warm exhaust, the circuit cannot reject heat and the cabinet warms no matter how long the compressor runs. Last on this list, and the item that every cause above it can imitate exactly.
Check in this order, and why that order
- Start at the heat path: 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. This comes first on this family because it costs nothing, needs no tools and rules out the most common cause in one look.
- Check the door on its seal, all the way round — Close it on a strip of paper at several points and pull. A strip that slides freely anywhere tells you where the room is getting in.
- Read the set point and then read a thermometer — Put a thermometer in a glass of water in the cabinet overnight rather than measuring air. A refrigerator holds food safely at 40 °F (4 °C) or below; if the machine and the thermometer disagree, the sensor is the suspect.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off.

When to call a technician
Call when the cooling type is compressor and the fault is not the door, the racking load or the room. Call immediately if you can smell burning, if the machine trips protection repeatedly, or if there is oil rather than water in the machine bay — oil outside the tubing means the circuit is open, and every hour it runs after that costs more to put right. Before ordering anything, match the plate against the WBV variant table above. The family is a divided wine and beverage cabinet, and parts that look alike across a brand's other lines often do not fit it.
