The short answer
When a machine from the BCD family starts making a sound it did not make before, the useful first move is not to open it but to work out whether the sound stops when the compressor does. Most refrigeration noise is not a fault, and the useful work on this page is separating the sounds a working cabinet makes from the two or three that mean something has moved or worn.
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 gurgle or a bubbling sound after it stops — That is refrigerant settling, and it is normal on every cabinet of this kind. It is worth naming so nobody pays to have it investigated.
- A buzz or rattle that comes and goes with the compressor — Time it against the cycle. A sound that starts and stops exactly with the compressor is coming from something the compressor is shaking, not from the compressor itself.
- 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
- A pipe resting where it should be clear — The pipework at the back is routed with clearance on purpose. Anything that presses a line onto the shell - a move, a shove into a tight recess, a bracket - hands the compressor a direct route into a large flat panel, which is what a loudspeaker is. Several distinct bases means several depths, and the deeper cabinet pushed into a tight space is the one whose pipework ends up resting on something.
- Contact with the floor, the wall or the cabinetry — Second on this platform. Levelling and contact stay on the list to the end, because they are free to rule out and because they explain sounds that appear after a move with nothing having failed at all.
- Mounts that have stopped absorbing anything — Third here. Mounts that have hardened give a knock at each end of the cycle and lift the general noise floor. It is an age story rather than a breakage, and it is almost never 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.
- A compressor struggling to start — Last. Last, and the only entry here that is urgent: repeated clicking with no cooling means the compressor is not starting, and continuing to let it try is not free.
Check in this order, and why
- Press a hand flat on the top and the side — If the sound drops while you press, you are listening to a panel resonating rather than a part failing, and the fix is damping or clearance rather than parts. The 5 entries below sit on 4 different bases, so confirm your own code before carrying a neighbour's result across.
- Take the loading out of the equation — Bottles touching each other and a loose shelf make noises that sound mechanical from the next room. Empty the shelves once before assuming anything about the machine.
- 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
If the noise is steady, tracks the compressor and survives every free check, it is worth a visit rather than a parts order. Call immediately instead of testing further where there is a hiss and a smell, a tripping breaker, or clicking with no cold, and leave the cabinet isolated until someone has looked at it.
