The short answer
A new rattle, buzz or knock from the DL 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 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 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
- Levelling, feet and what the cabinet is touching — A cooling appliance vibrates constantly and quietly, and it only becomes audible when something is there to amplify it. A foot barely touching, a cabinet resting against a wall or a floor that flexes turns an inaudible machine into a loud one. 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 pipe resting where it should be clear — Second on this platform. A line resting on the cabinet is easy to overlook and quick to correct, and it is behind a good share of the buzzes that appear the same week a unit was moved.
- The fan, where the model has one — 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.
- Hardened compressor mounts — Fourth. 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.
- 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
- 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. All 2 entries in the table below sit on one base, so what this check tells you holds for every one of them.
- 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.
- 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
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.
