The short answer
Noise complaints on the RMX 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. Most refrigeration noise is not a fault, and the useful work on this page is separating the sounds a working cabinet makes from the two or three that mean something has moved or worn.
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 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.
- 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
- 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. 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 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.
- Something touching a fan blade — 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.
- Mounts that have stopped absorbing anything — 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.
- 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
- 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 3 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
Unplug the appliance or switch off its breaker before removing any panel, and remember that a capacitor can hold a charge after the power is off. Never reach into a fan opening to stop a blade or to feel for an obstruction while the unit is live, and never wedge the door switch to keep a fan running so you can listen to 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.
