The short answer
Noise complaints on the FFFDS family divide into the sounds every cooling appliance makes and the two or three that mean something has moved, worn or is touching what it should not. 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 deep hum that has got noticeably louder — A hum that has grown rather than appeared usually means the machine is running more, which is a cooling complaint wearing a noise costume.
- 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 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
- Contact with the floor, the wall or the cabinetry — 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. With a single catalogued model there is no build variation to chase, so where the machine stands accounts for nearly all of the difference between a quiet one and a loud one.
- Hardened compressor mounts — Second on this platform. 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 — Third here. 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.
- Contact between the pipework and the shell — 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
- 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. With one catalogued entry behind this page, whatever you find here is the answer for every owner of the model.
- 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.
- Rock the cabinet gently at each front corner — Any movement at all means a foot is not carrying its share, and a foot that is not carrying its share is the most common reason a quiet machine becomes a loud one.
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.
