The short answer
When a machine from the RMRC 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. 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 that is loudest at the back corner — Tubing that has been pushed against the cabinet skin - often when the unit was last moved - transmits everything the compressor does straight into the panel.
- 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 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.
- 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. 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.
- Tubing touching the cabinet — 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.
- 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.
- The fan, where the model has one — Fourth. 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.
- The one cause on this list that is not a nuisance — Last. Last, and the only entry here that is urgent: repeated clicking without cooling means the compressor is not starting, and every further attempt costs it something.
Check in this order, and why
- 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. All 5 entries in the table below sit on one base, so what this check tells you holds for every one of them.
- 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.
- 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.
