What this usually is on these models
Noise on the ZGW line separates cleanly into sounds that follow the fan, sounds that follow the compressor and sounds that follow the cabinet. A case in contact with a wall or a cupboard makes the neighbour rattle and starves the condenser at the same time, and that split does most of the diagnosis.
What you observe
- Ticking in time with something turning — A hard, even tick with a fixed interval, which is the signature of a blade brushing something.
- The noise is far worse in one room than another — The same unit, the same load, a different surface and a different amount of background sound.
- Runs longer than it used to and is louder for it — The sound may be unchanged and simply present for more of the day.
- NEAR MISS - clicking every few minutes with no run — That is a start attempt failing rather than a mechanical noise, and it points at the supply or the start circuit.
Ranked causes for these models
- The cabinet touching a wall or furniture — First here, and by a wide margin: it also starves the condenser of air, so the unit runs longer and makes its noise for more of the day, which is why the complaint often arrives in warm weather.
- Packing or a restraint left in place — Second on this line: units ship with foam, card or a strap holding the machinery still, and those are routinely left in after the first unpacking. Once the compressor starts moving on its mounts it drums against whatever is still touching it.
- Resonance through the surface it stands on — Third: a cabinet on a hollow worktop, a thin shelf or a bare board couples its hum straight into that surface, which radiates it. The unit itself may be quiet; the furniture is what you can hear.
- A worn fan bearing — Last on the list, and the only one here that is not owner work: it develops rather than appearing, gets worse in the cold, and is often quieter for a while after a run, which is how it is distinguished from a foul.
What to check first, second, third
- Pull the unit clear of everything it touches — Check the rear and the sides for a lead, a hose or a bracket resting against the case.
- Look for anything still touching the machinery — With the unit isolated, look into the machinery bay for foam, card, a cable tie or a strap still in contact. Remove only what is clearly packaging.
- Change what it stands on — Compare the noise with the unit on the floor against the noise on its usual stand.

Safety
Switch off at the breaker or pull the plug before any panel is disturbed, because a capacitor can hold a charge after the power is off. Do not defeat a door switch to keep a fan running while you listen; there are safer ways to place a noise.
When to call a technician
The line here is whether the noise survives an empty cabinet on a level surface with a hand-width of clearance. If it does, it is mechanical and it needs the bay opening, which is service work on this line.
