The short answer
On a Silhouette Professional refrigerator, the cabinetry around an installed unit is the first thing to suspect, ahead of the evaporator fan catching ice, with the compressor and its mounting grommets at the bottom of the list. On a machine fitted into cabinetry the order shifts towards the surround — what it breathes through, what it touches, and how it was aligned on the day it went in. More than one of the checks below needs no tools at all, and the last of these causes is a service call.
What you observe
- A loud buzz for a few seconds, then silence — The water valve filling an ice maker, which does this on a schedule whether or not it makes ice.
- Vibration through the floor — A unit that is not level, or feet that are not all carrying weight, transmitting compressor vibration into the room.
- A rattle that changes when you touch the cabinet — Something loose rather than something failing — a drain pan, a rear panel or a bottle inside.
- NEAR MISS — noisy and the cabinet is getting warm — Read the cooling page first. Noise with a warm cabinet is usually the fan that also moves the cold air.
Causes, most likely first on Silhouette Professional
- The cabinetry around an installed unit — A built-in refrigerator breathes through a grille rather than through the open back, and it is surrounded by panels that can touch it. Both matter for noise: a restricted grille makes the fans work harder, and a panel in contact rings. Ranked first on Silhouette Professional: on an installed unit the enclosure leads, because it both amplifies noise and makes the fans work harder for the same cooling.
- The evaporator fan catching ice — This is the noise that means something. Second here: the door test separates it from everything else in seconds, and it is the noise most likely to be telling you about a second fault behind it.
- The ice maker and its fill valve — An ice maker is a noisy device by design: the valve buzzes as it fills, the mould heats and releases, and the cubes drop into a bin that acts as a drum. Third, once the two above are clean: this ranks where it does because the noise is loud, alarming and almost always working as designed.
- The compressor and its mounting grommets — A compressor that has become loud is usually either poorly isolated or running far more than it used to. Bottom of the list, deliberately: it is here because a louder hum is often a mounting problem rather than a failing compressor, and the two are worth separating.
Check in this order, and why
- First: Check the grille and the clearances — Make sure the grille is clear and nothing rests against the sides or the back of the cabinet. It is first because it is the cheapest of the three to settle.
- Second: Open the freezer door while it is noisy — If the noise stops the instant the door opens, it is the evaporator fan and nothing else.
- Third: Switch the ice maker off for a day — If the noise goes with it, the ice maker was the source and not a fault elsewhere.
What an owner can safely check
- Clear the ventilation grille and check clearances — Vacuum the grille, then slide a card down each side to find anything touching.
Tools: vacuum, thin cardAbout 20 min
- Listen at the freezer with the door open and closed — Note whether the noise stops with the door open. Do not force the rear panel off.
About 10 min
- STOP HERE if the next step needs a meter on live terminals — That is the line between an owner check and a service call, and it is not worth crossing.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel, and treat every capacitor as still charged: a capacitor can hold a charge after the power is off. Secure or remove the doors before moving a unit, get help with the lift, and never lay a refrigerator on its back. Do not put a heat gun anywhere near a cabinet full of plastic.
When to call a technician
Everything above that is done with a vacuum, a torch and a spanner is owner work. Past that, the panels come off and the unit has to be isolated first.

What this page does not cover
This is generalized information for Silhouette Professional refrigerators as a class, not for one family or one model. No family- or model-specific page for this brand and appliance is published here yet, so nothing narrower is linked; when one is, it becomes the more specific answer and this page will point to it. Not here: wiring colours, torque figures, part numbers and panel-removal sequences, all of which differ by family.
