The short answer
Abnormal noise or vibration on a TWW refrigerator usually comes down to something loose rather than something broken: a basket, a divider or a lead touching a fan makes more noise than a compressor ever does. The order that follows puts the likeliest and cheapest causes first, and it is the order worth working in rather than starting with the part that sounds most serious.
What you actually observe
- 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.
- A buzz or hum that changes when the unit is nudged — Transmission through the surface, not a fault inside the cabinet.
- Gurgling and light ticking after the compressor stops — NEAR MISS: normal refrigerant settling in the sealed system, not a fault at all.
- Body: The spread between TWW35 and TWW115 is wide enough that the two ends of the TWW roster do not behave alike under load.
What causes it on the TWW platform, in likelihood order
- 1. How and where it is standing — This is the first check for a reason: it costs nothing, and moving a unit half a metre or slipping a mat under it settles a surprising number of noise complaints permanently. Mechanical wear moves up the TWW order because the top of the roster loads the same parts that TWW35 barely troubles.
- 2. Things moving inside the cabinet — The wire basket, the divider and anything packed loosely all sit close to the compressor's vibration. Owners describe this as an electrical buzz far more often than as a rattle, because the frequency is the compressor's rather than the object's. Second on TWW: it takes longer to confirm than the cause above it, and it rarely arrives without warning.
- 3. Aged compressor mounts — The signature is gradual: nothing broke, and nobody can name a day when it changed.
- 4. How it is strapped and what it touches — Strapped tight against a panel, the panel becomes the sounding board. Contact at a single point, often a strap buckle or a corner touching trim, carries more noise than the whole rest of the installation.
The order to work in on this platform
- 1. Lift it clear of the surface briefly while it runs — If the noise changes or disappears, the surface was the amplifier.
- 2. Take the basket, divider and contents out and listen again — Removes the cheapest cause in one move.
- 3. 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.
Before you open anything
Safety
Isolate before investigating: unplug the appliance or switch off its breaker, and treat a capacitor as charged even after power is removed. Keep hands out of a running fan, and never pack material against a compressor to damp it, because what it is actually doing is blocking the airflow that keeps it alive. No two TWW listings share a base number, so each one in the table is a distinct machine rather than a revision of its neighbour.

When to call a technician
Call for a metallic knock that rises with load, or for a click every few minutes that never turns into a run. Both are the compressor and its start circuit, and neither gets better with time. With six listings in the TWW table, quote the full model number when ordering anything: the differences between them are exactly the differences that matter to a parts counter.
