The short answer for this family
On the Alpicol RTW family, a cabinet making a noise it did not make before is usually a panel, shelf or item in the cabinet resonating. One model in the family means the matrix cannot narrow anything for you, so the order below runs from what costs nothing to check to what costs a visit. The brand-generic article for this symptom ranks sounds that are normal for this machine first; on this platform it does not.
What you observe on these models
- Which of the family's models you are standing in front of — The matrix on this page is one model, so there is no variant question to answer, and that is worth reading first, because one model in the family means the matrix cannot narrow anything for you, so the order below runs from what costs nothing to check to what costs a visit.
- A buzz or rattle that comes and goes with the compressor — It starts when the machine starts and stops when it stops, which points at mounting rather than at the pump.
- A whine or click that stops when the door is opened — Opening the door cuts the evaporator fan, so a noise that dies with the door is that fan.
- A crack or pop a few times a day — Metal expanding and contracting through a cycle. It is loud, it is sudden and it is normal.
Causes, most likely first on the RTW family
- A panel, shelf or item in the cabinet resonating — Ranked first because one model in the family means the matrix cannot narrow anything for you, so the order below runs from what costs nothing to check to what costs a visit.
- Sounds that are normal for this machine — Second. The duty here is a compact cabinet run continuously at one setpoint, so a unit that is asked to work harder simply makes its normal noises more often.
- A fan blade fouling its shroud or a worn fan bearing — Third. A dry bearing whines rather than clatters, and the note rises as the cabinet warms.
- The compressor and its mounts — Fourth. Less common than the causes above, and the least pleasant to confirm without removing the rear panel.
- A sealed-system or compressor fault — Last, and that placement is the point of the ranking: it is the least common cause and the only one that is not an owner fix.
- Body: This is not the brand-generic ranking. A panel, shelf or item in the cabinet resonating moves to the top of this family's ranking and sounds that are normal for this machine goes down to second place, because the platform here is a single compact build with one cooling circuit.
Check in this order on these models
- Lay a flat hand on each panel in turn while it is running — A noise that changes under your hand has just told you which panel is passing it on.
- Time the noise over a day — A noise that appears a handful of times and lasts a short while is a cycle doing its job.
- Open the door and hold the door switch in — If the noise appears with the switch held and dies when you let go, it is the evaporator fan and nothing else.
- Listen at the machine compartment through a start and a stop — A noise that arrives with the compressor and leaves with it is a mounting question, not a cabinet one.
- Body: The order follows the ranking, and the access decides the rest: on these models the machine compartment is at the rear base of the cabinet.
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 hold the door switch in with tape and then reach inside: the fan is running because the switch is defeated, and it will not stop for your hand.

Where the owner limit falls on these models
Call when the noise is inside the machine compartment, when it is accompanied by a cabinet that has stopped holding temperature, or when it is a grinding rather than a rattle. A noise on its own, with the cabinet still cold, is rarely urgent. A noise with a rising cabinet temperature is, because the two together point at the fan that moves the cold air.
