The short answer
When a machine from the AVRPD 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. 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 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.
- 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.
- 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
- Contact between the pipework and the shell — 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.
- Contact with the floor, the wall or the cabinetry — Second on this platform. Levelling and contact stay on the list to the end because they cost nothing to rule out and because they explain a noise that arrived after a move with nothing at all having failed.
- 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. 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.
- 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
- 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. The 3 entries below sit on 3 different bases, so confirm your own code before carrying a neighbour's result across.
- 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.
- Press a hand flat on the top and the side — If the sound drops while you press, you are listening to a panel resonating rather than a part failing, and the fix is damping or clearance rather than parts.
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.
