The short answer
On AVG MVP the honest first answer is that a commercial-style undercounter cabinet that will not hold temperature is far more often a heat-rejection or airflow problem than a dead compressor. This is 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, and every one of those elements can stop the cabinet cooling while the machine still sounds perfectly normal.
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.
- One part of the interior is right and another is not — A temperature that varies across the cabinet is an airflow report.
- 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 MVP
- Blocked airflow inside the cabinet — Cold that is made correctly and then cannot circulate produces exactly the same complaint as cold that was never made: a warm cabinet with a machine that is plainly working. Forced-air cabinets rely on a clear return; stock pushed to the back of the shelf closes it. Ranked first here rather than further down, because an undercounter cabinet gives this cause more opportunities than any other on the list.
- A failed circulation or condenser fan — A fan that has seized, slowed or lost its supply removes the moving air the design depends on, and the fault appears as a cabinet that is cold in one place and warm everywhere else.
- 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.
- 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. 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. 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 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. Before ordering anything, match the plate against the MVP variant table above. The family is an undercounter cabinet, and parts that look alike across a brand's other lines often do not fit it.
