The short answer
The AVG MVP models covered here are commercial-style undercounter cabinets, and that construction decides which noises they make: 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. 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 commercial-style undercounter 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 MVP
- 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. Forced-air cabinets always have one and it runs almost continuously. Ranked first on AVG MVP, which is an undercounter cabinet: that construction moves this cause ahead of where the generic ordering puts it.
- 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.
- 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.
- 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. 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.
- 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: 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 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. One more thing that is specific to this family: the MVP variant table on this page is the whole of what is covered here — a single model number and nothing else. If the plate on your machine is not one of them, the ranking above was not written for it.
