The short answer
On a TW refrigerator the usual explanation for abnormal noise or vibration is the surface it stands on rather than the machine: a compressor bolted into a small cabinet transmits everything it does into whatever is underneath. Work the order below rather than the order of expense: the two cheapest checks settle most of these before a tool comes out.
What you actually observe
- A rattle that comes and goes with the compressor — Something loose that only resonates at the compressor's frequency.
- A ticking or whirring that rises and falls — A fan with something in its path, or a fan losing balance.
- A loud run that settles down after a while — Speed, not damage: a compressor asked to pull down quickly is louder than one holding temperature.
- No noise at all and nothing cooling — NEAR MISS: that is a cooling or supply fault, and the not-cooling page covers it properly.
- Body: The TW roster covers six listings, TW35 through TW115, and what follows is common to all of them unless a step says otherwise.
Causes, most likely first on the TW platform
- 1. The surface underneath it — A small cabinet with a compressor in one corner is a loudspeaker for its own machinery. On a thin floor, a drawer slide or a hollow locker, the same unit that was quiet on concrete becomes intrusive. Mechanical wear moves up the TW order because the top of the roster loads the same parts that TW35 barely troubles.
- 2. Aged compressor mounts — The signature is gradual: nothing broke, and nobody can name a day when it changed. Second on TW: it takes longer to confirm than the cause above it, and it rarely arrives without warning.
- 3. Things moving inside the cabinet — The wire basket, the divider and anything packed loosely all sit close to the compressor's vibration. They buzz at one narrow frequency, which is why the noise seems to come and go.
- 4. The speed the compressor has been set to run at — Before any part is suspected, it is worth knowing whether the unit is in its loudest legitimate state. A variable-speed compressor asked for maximum output is meaningfully louder than one in an economy mode, and after a warm load it will sit at maximum for a long time.
What to check first on these TW models, and why
- 1. Lift it clear of the surface briefly while it runs — If the noise changes or disappears, the surface was the amplifier.
- 2. Press gently on the cabinet while it runs and listen for a change — A noise that dampens under hand pressure is transmission, not mechanical damage.
- 3. Take the basket, divider and contents out and listen again — Removes the cheapest cause in one move.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Never reach into a vent face while the unit is running to stop a fan by hand, and never wedge anything against a fan or a compressor to quieten it. The spread between TW35 and TW115 is wide enough that the two ends of the TW roster do not behave alike under load.

When to call a technician
The line is the compressor. Surfaces, baskets, fans, modes and mounts are all owner checks that cost minutes; a knocking or non-starting compressor needs a technician, particularly if cooling has fallen off with it. No two TW listings share a base number, so each one in the table is a distinct machine rather than a revision of its neighbour.
