Start here
A T unit that has become noisy is, more often than not, telling you about the room it is in. A noise that arrived with a move is about the new position, not about a new fault, so the ranking here puts position and load above machinery. The first check on this line is the simplest one - change what it stands on - and the cause at the bottom of the list is the only one that is not owner work.
The observables
- A rattle that comes and goes within a run — It appears for a few seconds at a particular point and then clears on its own.
- A continuous whine while air is moving — It tracks the fan rather than the compressor and stops when the fan does.
- A buzz that you can feel through the case — Felt as much as heard, and it changes if you rest a hand on a panel.
- NEAR MISS - loud and the cabinet is warming — Noise with a cooling complaint is a cooling fault first. The not-cooling page for this line covers it, and it is the combination that needs a technician.
Causes, most likely first on this line
- Resonance through the surface it stands on — First here, and by a wide margin: the tell is that the noise is much louder in one room, or one position, than it was in another, with nothing about the unit changed.
- The cabinet touching a wall or furniture — Second on this line: a case pressed against a wall, a cupboard or another appliance transmits vibration directly into it, and the second object rattles at its own frequency. That rattle is what gets reported, not the compressor.
- The cabinet not standing squarely — Third: stance is first because it is free to test and it explains the loudest complaints: the noise changes the moment the unit is shifted a hand-width.
- Compressor mounts that have perished — Last on the list, and the only one here that is not owner work: this is a genuine machine fault and the point at which the owner checks run out: confirming it means getting into the machinery bay with the unit isolated.
The order to work in
- Change what it stands on — Put a dense mat or a slab of board under the unit and listen again. A large change in level from that alone identifies the surface as the amplifier.
- 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.
- Press each corner in turn — Press down on each corner of the top. Any corner that moves is the one making the noise, and packing it out is the whole repair.
Before any panel comes off
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. A fan can start without warning while the unit is live, so never reach into a machinery bay to feel for a noise on a running unit.

When this stops being owner work
Two things make this a service call rather than a check: a noise that has grown steadily over weeks alongside longer running, and any noise at all with a hot or electrical smell. Everything else on this list is free to test first.
