The short answer
On a Capital built-in refrigeration column this complaint is usually the joinery around it acting as a soundboard rather than the failure owners fear, and where it is not, a fan blade catching on frost or a wire takes most of the rest. A column is built into the cabinetry, ducted to a grille and levelled to the millimetre, so installation faults live on for years and present as cooling faults. That order is what this page is for, because working it the other way round is how an afternoon gets spent on the least likely cause.
What you observe
- The floor or the worktop carrying the noise — A cabinet that is transmitting rather than making the sound.
- A flutter or a regular ticking from inside — Something is touching a turning blade.
- NEAR MISS - a grinding or screeching that rises and falls — Stop and unplug it. That is a bearing or a blade, and running it on turns a part into a repair.
Causes, most likely first on this brand
- Cabinetry transmitting the cabinet's own vibration — Top of the list here: a column is fixed to the joinery it stands in, so a panel or a filler strip touching it turns the whole run of cabinets into a soundboard.
- A fan blade catching on frost or a wire — Second here: the fan turns whenever the cabinet is cooling, so anything it brushes against produces a regular ticking or a flutter that follows the cooling cycle exactly.
- A cabinet standing unevenly — Third, and worth the two minutes: on three feet instead of four the whole shell rocks each time the compressor starts, and a soft floor or a carpet tile is enough to do it.
- The compressor or its mounts — Last, and the reason the order matters: it is last because a compressor that is noisy but still cooling is usually just an old compressor on tired rubber mounts, and that is a judgement rather than a repair.
Check in this order, and why
- Check for clearance between the column and the joinery around it — On a built-in this is where most reported noise actually lives.
- Listen at the freezer with the door open — It identifies a blade fault without taking anything apart.
- Rock each corner and watch whether it moves — Second because it is nearly as common and just as cheap to rule out.
What an owner can safely check
- Check the filler panels and the kickplate are not touching the cabinet — On a built-in the joinery is the loudspeaker, and a millimetre of clearance silences it.
Tools: torchAbout 20 min
- Open the door and listen at the freezer for a flutter — A blade catching on frost changes note when you open the door, which is how you identify it.
About 5 min
- Rock each front corner and adjust the feet until it sits solid — A cabinet that rocks on the diagonal will buzz every time the compressor starts.
Tools: spirit levelAbout 15 min
- STOP HERE if the noise is grinding, screeching or metallic — That is a moving part failing. Unplug it and stop, rather than running it to see what happens.
Before you open anything
Safety
Switch the column off at its breaker before removing the base grille or any panel; a built-in is often hard-wired or fed from an outlet behind the cabinetry. A capacitor can hold a charge after the power is off. Do not attempt to pull a column out of its opening alone - they are tall, heavy and anchored to the joinery.
When to call a technician
Call once the joinery is clear of the cabinet and the noise remains, and call earlier than you would on a freestanding appliance. Diagnostics on a column happen behind panels that come off in a particular order, and a forced panel on fitted cabinetry costs more than the repair it was hiding.

What this page does not cover
This page covers built-in refrigeration columns as a class, not one model line or installation. Panel clearances, anti-vibration mounts and grille dimensions differ by family, and where a family- or model-specific page exists it is linked below and is the more specific answer. Not here: clearance figures, torque values and part identifiers.
