The short answer
When a machine from the MCCF 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 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.
- 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.
- 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.
- 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 cost nothing to rule out and because they explain a noise that arrived after a move with nothing at all having failed.
- 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 fan fouling on ice or a wire — 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 one cause on this list that is not a nuisance — 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
- 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 2 entries below sit on 2 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
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
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.
