The short answer
When a machine from the FFFD 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 that is loudest at the back corner — Tubing that has been pushed against the cabinet skin - often when the unit was last moved - transmits everything the compressor does straight into the panel.
- 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.
- 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 - it clicks every few minutes and never cools — Clicking on a cycle with no cooling is a start-relay or compressor complaint, and it belongs with the cooling fault page and then with a technician.
Causes, most likely first on this platform
- Contact between the pipework and the shell — 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.
- Levelling, feet and what the cabinet is touching — 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.
- Hardened compressor mounts — 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.
- 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.
- 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 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
Power the machine down at the plug or the breaker before you go behind a panel, and give the capacitor a moment. Do not chip ice away from a fan blade with anything metal - the tubing behind it punctures easily - and do not defeat an interlock to keep something spinning while you look at it.

When to call a technician
Call when the free checks are clean and the noise is still there, because at that point it is behind a panel and behind a meter. Call without waiting if the sound is short bursts of clicking with no cooling between them, if a breaker trips when the machine starts, or if a burning smell has come with it - those are the three noises that get worse and more expensive the longer they run.
