Start here, for WBV models
New noise from an Avanti WBV refrigerator sorts into three families: a rattle (something loose), a hum or buzz (a fan or a transformer working against resistance), and a rhythmic click or gurgle (which is usually normal operation). On these machines the first family is by far the most common, and it is owner-fixable.
Signs you can observe
- A knock once or twice a day and never otherwise — On this family, noise that keeps a schedule is usually the machine working, not failing.
- A rattle or buzz that comes and goes with the cooling cycle — On WBV models, cycle-linked noise means a fan, the compressor mounts, or tubing vibrating against the cabinet.
- A sharp clatter for a second on start-up, then silence — On WBV models, a fan blade clipping ice or a shroud makes exactly this short burst as it comes up to speed.
- A buzz that follows the ice maker filling — Where WBV models are concerned, the fill valve, and it is the one noise in a refrigerator that has a simple owner test.
- Gurgling, trickling or a soft pop after it cycles off — On WBV models in particular, these are healthy noises: a machine that makes none of them is usually not running at all.
- NEAR MISS — loud running AND a warm cabinet — Then noise is the symptom and temperature is the fault. Read the cooling-failure page for your model line first.
What actually fails on WBV models, in order
- A cabinet that is not level or is resting on cabinetry — It leads the list because a single foot off the floor turns the compressor into a drum skin — and because the fix is a spanner and five minutes.
- Perished compressor mounting grommets — Rubber mounts harden with age and the compressor then hums straight into the cabinet instead of being isolated from it. On WBV models it earns that place.
- Ice contact caused by a defrost fault — A fan striking a growing ice sheet starts as a tick and becomes a clatter, and the underlying fault is the defrost system.
- A failing compressor — Last, as it should be: a genuinely failing compressor is rare next to everything above and it is licensed work. It sits there for WBV models too.
The order to work in
- Open the door and listen for the noise to stop — On WBV models in particular, do this first every time: it halves the candidate list at zero cost.
- Press a finger on the suspect panel or tube while it hums — If the note changes or stops, you have found the contact point and a foam pad or a cable tie is the repair.
- Check the clearance around and above the cabinet — Looking at WBV models specifically, leave the gap the installation instructions call for, especially at the back where the coil rejects heat.

Safety
Unplug the refrigerator or switch off its breaker before a panel comes off or a hand goes near a fan — a capacitor can hold a charge after the power is off, and a fan blade that starts while your fingers are in the shroud is the injury this fault actually causes. Do not open the sealed system to chase a noise: that is licensed work.

When to hand it over
Hand it over once the three cheap causes are ruled out: level, clearance and contact. A dry bearing behind the rear panel needs the cabinet emptied and the panel off, and a hum from the compressor mounts needs the unit lifted. If the noise came with a loss of cooling, treat the cooling fault first and let the noise follow it.
