The short answer
When a machine from the FFFDD 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. Noise is the cheapest fault a cabinet can have and the one most often misread, because the loudest sounds a refrigerator makes are usually the most innocent ones.
What you observe on these models
- 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.
- 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 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 - 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
- A unit that is not sitting square — 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.
- Something touching a fan blade — Third here. 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.
- A pipe resting where it should be clear — 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 start relay or the compressor itself — 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
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
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.
