The short answer
A new rattle, buzz or knock from the AVRM family is far more often about where the cabinet stands than about anything inside it, and the checks that prove that are free. 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 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 rhythmic ticking or clicking from the back — Regular, slow ticking is usually expansion and contraction in the tubing. Fast clicking in short bursts, followed by silence, is a different matter entirely.
- 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 - the sound is a hiss and there is a smell — Stop there. Isolate the cabinet and call a technician rather than working through this page.
Causes, most likely first on this platform
- Tubing touching the cabinet — The pipework at the back is routed with deliberate clearance. Anything that pushes a line against the shell - a move, a shove into a tight space, a wall bracket - gives the compressor a direct path into a large flat panel, which is exactly what a loudspeaker is. Several distinct bases means several depths, and the deeper cabinet pushed into a tight space is the one whose pipework ends up resting on something.
- Something touching a fan blade — Second on this platform. 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 rubber the compressor sits on — Third here. 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.
- Levelling, feet and what the cabinet is touching — Fourth. Levelling and contact stay on the list to the end, because they are free to rule out and because they explain sounds that appear after a move with nothing having failed at all.
- 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
- Take the loading out of the equation — Bottles touching each other and a loose shelf make noises that sound mechanical from the next room. Empty the shelves once before assuming anything about the machine. The 3 entries below sit on 2 different bases, so confirm your own code before carrying a neighbour's result across.
- 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.
- 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.
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.
