The short answer for the NPYXX models
On the Alcove NPYXX refrigerator models, a noise or a vibration that is new leads with a fan blade catching ice or a stray item rather than with the cause the brand-generic article opens on. The spine for the NPYXX family records a single model code, so this is one cabinet rather than a platform run, and everything below is written for that one build.
What you observe on these models
- Gurgling or trickling after the unit stops — Refrigerant settling. Normal, and often the first sound noticed in a newly quiet room.
- A buzz or a hum that starts with the compressor — It comes and goes with the running cycle rather than being constant.
- Clicking every few minutes with no change in cooling — A relay trying and failing to start, or a normal control cycling — those sound alike and mean very different things.
- NEAR MISS — the noise is a hiss and something smells sharp — Stop, unplug and call. That is not a noise complaint.
Causes, most likely first on the NPYXX family
- A fan blade catching ice or a stray item — Ice builds where the air passes, and the blade finds it. The noise usually stops when the freezer door is opened, because the door switch cuts the fan. Ranked first here.
- The condenser fan or its shroud — A noise that stops the moment the compressor stops, and never changes when the doors open, is pointing at the warm end of the cabinet. Second.
- The compressor itself — A knocking or labouring noise from the compressor, or a relay clicking without a start. Last, and that is the point of the order.
- Body: The cause that moves up on these models is a fan blade catching ice or a stray item; what moves down to make room for it is the condenser fan or its shroud, which is where the brand-generic article for this symptom opens.
Check in this order, and why
- Open the freezer door while the noise is happening — First: On most cabinets that cuts the fan. If the noise stops, the fan is making it.
- Feel the condenser fan grille for airflow and for dust — Second: A choked shroud makes its own noise and is reachable without opening the cabinet.
- Work out whether the sound tracks the compressor or runs constantly — Third: A noise that stops when the compressor stops is at the warm end; one that does not is elsewhere.
Before you open anything
Safety
Isolate the cabinet first: pull the plug or drop the breaker, and do it before a screwdriver is picked up. Stored charge and an unannounced fan are both waiting behind the panel. Anything on the sealed side needs a licence and tools an owner does not have. While you work, protect the food: a refrigerator holds it safely at 40 degrees Fahrenheit, 4 degrees Celsius, or below.

When to call a technician
Call when the checks above have been done and the fault is still there, or as soon as the evidence points at the compressor itself — that is the one cause here that is not owner work. Call immediately, and unplug the cabinet first, if you smell burning, see oil around the compressor, or hear a hiss with a sharp smell.
