The short answer
On a WTW 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 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 sharp click every few minutes with no run afterwards — A start attempt that is not completing, which is the one noise on this list to take seriously.
- 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 WTW roster covers two listings, WTW20 through WTW25, and what follows is common to all of them unless a step says otherwise.
Causes, most likely first on the WTW platform
- 1. 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. It ranks here because the two WTW listings share their running gear, so both wear through the same sequence.
- 2. The condenser fan and what is near it — Dust builds unevenly on a blade too, and an out-of-balance fan hums at a pitch nothing else in the unit produces. It comes second because the check above it costs nothing, where this one usually means moving the machine.
- 3. 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.
- 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 quiet mode and a settled load answer many noise complaints.
What to check first on these WTW models, and why
- 1. Take the basket, divider and contents out and listen again — Removes the cheapest cause in one move.
- 2. Look into the vent face for anything resting on the blade — A tick that follows the compressor is nearly always this.
- 3. Lift it clear of the surface briefly while it runs — If the noise changes or disappears, the surface was the amplifier.
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. No two WTW 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
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. There are two WTW listings, WTW20 and WTW25, and nothing below distinguishes between them unless it says so.
