The short answer
A new rattle, buzz or knock from the FC family is far more often about where the cabinet stands than about anything inside it, and the checks that prove that are free. A cooling appliance is never truly silent, so the question is never whether it makes a noise but whether the noise is new, and whether it changes when the compressor stops.
What you observe on these models
- 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 rhythmic ticking or clicking from the back — Regular, slow ticking is usually expansion and contraction in the tubing. Fast clicking in short bursts, followed by silence, is a different matter entirely.
- 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.
- 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. These entries share one base and therefore one cabinet, so a new noise is almost always about installation rather than about which trim was bought.
- A fan fouling on ice or a wire — Second on this platform. 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.
- 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.
- Tubing touching the cabinet — Fourth. 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 one cause on this list that is not a nuisance — 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
- Open the door and listen again — A sound that changes the moment the door opens is tied to the fan or to the airflow. A sound that ignores the door is behind the cabinet. All 3 entries in the table below sit on one base, so what this check tells you holds for every one of them.
- 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.
- Time the sound against the cycle — Note whether it starts with the compressor, runs continuously, or comes in short bursts followed by silence. Those three patterns point at three different causes.
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.
