The short answer
On the Alpicool ET refrigerator a new noise is more often about how the cabinet is standing and what is touching it than about anything inside the sealed system. The model record for this family is a single code, ET60, so everything below applies to one build rather than to a range of them.
What you observe
- A buzz or rattle you can stop with a hand — Touch a panel or a tray and the noise changes or disappears.
- A whine or whirr that rises and falls — Tied to a fan rather than to the compressor, and it often lingers a few seconds after the compressor stops.
- A drone or hum that carries through the room — Steady, present only while the compressor runs, and usually worse at night because the room is quieter.
- NEAR MISS — the noise arrived with water on the floor — Read the water-leak page for this family first; a drip tray that has shifted makes both symptoms at once.
Causes, most likely first on this family
- The fan, and whatever has found its way into it — First. A fan is the only part that spins all day, so it is the part that tells you when it is tired. A dry bearing whines and the note tracks the fan speed; a blade that has picked something up ticks once per turn. Both stop the moment the fan does. The record holds only ET60, so this check is the whole of the family's exposure to that cause.
- Something touching that should not be — Second. Almost every rattle on this appliance class is two things touching that were never meant to: a tube against a panel, a tray against a rib, a bottle against a shelf edge. Each one is found with a hand and fixed without a tool.
- A compressor that is trying to start and not managing it — Last. A repeated clack every few minutes, sometimes with the lights dipping, is a compressor attempting a start and being dropped again — a start component or a supply that sags under the load. It is a noise complaint on the surface and a cooling fault underneath.
- Body: With one code recorded there is no older or newer build here to tell apart. The record does not say what the numbers in the codes stand for, which is why this page reasons from what the cabinet does rather than from a specification. Where the record cannot tell you which codes carry a fan and which do not, the fan is settled first by ear: it either outlives the compressor by a few seconds or it does not, and that single observation splits the list in half.
First, second, third
- Time the noise against the fan, not against the compressor — Note whether the sound starts with the compressor or lingers after it stops. A noise that outlives the compressor by a few seconds belongs to a fan. On ET60 that is the whole of this step.
- Press on panels and move the contents while it runs — A noise you can stop by putting a finger on a panel is a contact noise. Note where it goes quiet before you start unscrewing things.
- Body: The record holds one code for this family, so the order below is not a model matrix — it is the order in which these causes can be eliminated on the machine in front of you, cheapest and least invasive first.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before removing any panel, because a capacitor can hold a charge after the power is off. Nothing in the order above needs the machine open. Never wedge a tool between tubing and cabinet to stop a buzz: the tubing is thin, it is under pressure, and a puncture ends the machine.

The line between a fix and a service call
Call when the noise survives every check above — the cabinet moved, level, nothing touching, contents settled — and especially when it is a grinding or a screech rather than a hum, because those are bearings rather than couplings. Call immediately if the noise comes with a cabinet that is losing temperature, or with a burning smell: at that point it has stopped being a noise complaint.
