The short answer
When a machine from the BD 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. The complaint that brings these units in is almost always a rattle, a buzz or a hum that has appeared recently, and almost all of it traces to contact rather than to a failing part.
What you observe on these models
- 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.
- A knock when it starts and again when it stops — A single knock at each end of the cycle is the compressor moving on its mounts. Once those have hardened, that movement stops being absorbed.
- 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.
- 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 deliberate clearance. Anything that pushes a line against the shell - a move, a shove into a tight space, a wall bracket - gives the compressor a direct path into a large flat panel, which is exactly 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.
- Something touching a fan blade — Second on this platform. Where a model has a fan, ice or a stray wire against the blade is worth checking, though it needs a panel off and so it sits below the free checks.
- Hardened compressor mounts — 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.
- A unit that is not sitting square — Fourth. Levelling and contact stay on the list to the end because they cost nothing to rule out and because they explain a noise that arrived after a move with nothing at all having failed.
- 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
- 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. The 5 entries below sit on 4 different bases, so confirm your own code before carrying a neighbour's result across.
- 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.
- 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.
Before you open anything
Safety
Isolate at the plug or the breaker before any panel comes off. A cabinet is heavy and top-shy once the door is open, so get help before walking it out from a tight space rather than levering it on one corner. If the noise comes with a burning smell or a tripping breaker, stop and call rather than diagnosing further.

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.
