The short answer
Noise complaints on the BCS family divide into the sounds every cooling appliance makes and the two or three that mean something has moved, worn or is touching what it should not. Noise is the cheapest fault a cabinet can have and the one most often misread, because the loudest sounds a refrigerator makes are usually the most innocent ones.
What you observe on these models
- A scraping or chirping that changes with the door open — Where a model has a fan behind a panel, ice or a stray wire touching the blade gives a sound that changes as soon as the airflow does.
- A deep hum that has got noticeably louder — A hum that has grown rather than appeared usually means the machine is running more, which is a cooling complaint wearing a noise costume.
- Vibration you can feel through the floor or the worktop — Vibration carried into the structure is nearly always a levelling or contact problem, and it is often worst on a floor that flexes.
- NEAR MISS - the noise arrived with water on the floor — Noise plus water usually means something has shifted or a drain has blocked, and the water leak page for this family is the better starting point.
Causes, most likely first on this platform
- Levelling, feet and what the cabinet is touching — These machines vibrate constantly and inaudibly, and they only become loud when something is there to amplify them. A foot barely in contact, a cabinet leaning on a wall or a floor with flex in it will do exactly that. With a single catalogued model there is no build variation to chase, so where the machine stands accounts for nearly all of the difference between a quiet one and a loud one.
- Tubing touching the cabinet — Second on this platform. A line resting against the cabinet is easy to miss and easy to fix, and it accounts for a good share of the buzzes that appear immediately after a unit has been moved.
- The rubber the compressor sits on — Third here. Hardened mounts produce a knock at each end of the cycle and a general increase in transmitted noise. It is an age fault rather than a breakage, and it is rarely urgent.
- Something touching a fan blade — Fourth. On a model that has a fan, ice or a stray wire touching the blade is worth a look, though confirming it means a panel off, which is why it sits under the free checks.
- The start relay or the compressor itself — Last. Last, and the only entry here that is urgent: repeated clicking without cooling means the compressor is not starting, and every further attempt costs it something.
Check in this order, and why
- Wait for the compressor to stop, then listen — This one test splits the list in half. Whatever is still audible after the machine has gone quiet is not the machine, and whatever vanishes with it is being driven by it. With one catalogued entry behind this page, whatever you find here is the answer for every owner of the model.
- Rock the cabinet gently at each front corner — Any movement at all means a foot is not carrying its share, and a foot that is not carrying its share is the most common reason a quiet machine becomes a loud one.
- Pull it out and look at what is touching — Check the back panel against the wall, the sides against the cabinetry and the pipework against the shell. Half of these complaints end here, with nothing broken.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel, and remember that a capacitor can hold a charge after the power is off. Never reach into a fan opening to stop a blade or to feel for an obstruction while the unit is live, and never wedge the door switch to keep a fan running so you can listen to it.

When to call a technician
Levelling, contact and loading are yours; a bearing, a relay or a compressor is not. Go straight to a call if the machine clicks in bursts and then falls silent without ever cooling, and isolate it while you wait rather than letting it keep trying, because each failed start costs it something.
