The short answer
The AVG VPB models this page covers share one construction and therefore one failure pattern: a heavier cabinet built for frequent opening and a warm room, with forced-air cooling, a coarse condenser behind a front or rear grille and a drain arrangement designed to run continuously. 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 commercial-style undercounter 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.
- The cabinet recovers overnight and drifts by day — That pattern points at the room rather than the machine, and it is the single most useful thing an owner can notice.
- 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 VPB
- 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. This is the first check on a commercial-style cabinet and it is the single most common root cause on this class. It leads the list on AVG VPB because these are commercial-style undercounter cabinets — an upright cabinet concentrates this fault in a way a full-size machine does not.
- 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.
- The room the cabinet is standing in — Every cabinet is rated against an ambient range. Outside it the machine is not faulty, it is beaten, and it presents as a unit that runs continuously and still drifts warm. 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: look at the condenser before anything else — on this class of cabinet it is the single most common root cause and the cheapest to rule out — The front grille and the machine bay behind it, and the interior rear panel once the shelving is out.
- Look at how the cabinet is loaded and where the air returns — This cabinet is specified to work in a warmer, busier room than a domestic one, which means it runs closer to its limit and shows a neglected condenser sooner, so pull the load a hand-width off the rear wall and give it a day before concluding anything.
- Only then consider the sealed system — By this point four cheaper causes are eliminated.
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 condenser is clean, the door closes on its seal, and the cabinet still will not pull down in a warm 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. Check the plate before acting on any of this. VPB is an upright cabinet, and the ranking above is written for that construction rather than for the brand as a whole.
