The short answer for the NN models
On the Alcove NN refrigerator models, a noise or a vibration that is new leads with something loose on, in or behind the cabinet rather than with the cause the brand-generic article opens on. The spine for the NN family records one model code, which is to say the family and the machine are the same thing.
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 — it is noisy and it has also stopped getting cold — Two symptoms together point at the cooling page rather than at this one.
Causes, most likely first on the NN family
- Something loose on, in or behind the cabinet — Bottles touching, a tray resting on the back wall, a drip pan out of its brackets. All free to find, none of them needs a tool. Ranked first here.
- The condenser fan or its shroud — This fan is the one nearest the floor, so it collects everything the room drops. What it collects is what makes it hum out of balance. Second.
- The compressor itself — Ranked last because it genuinely is: most new noises on a working cabinet are found above this line and cost nothing.
- Body: The cause that moves up on these models is something loose on, in or behind the cabinet; 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
- Clear the top, the sides and the back, then listen again — First: Half of these noises are objects, and objects are free to remove.
- 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.
- Pull the cabinet out of its surround and run it standing free — Third: If the noise drops away in the open, the cabinet is fine and the installation is what needs attention.
Before you open anything
Safety
Power off at the plug or the breaker before anything is opened. A capacitor keeps its charge after the switch, and the fan behind the rear panel can start on its own. The sealed refrigerant side is licensed work rather than owner work. Deal with the food first: a refrigerator holds food safely at 40 degrees Fahrenheit, 4 degrees Celsius, or below, and a freezer at 0 degrees Fahrenheit.

When to call a technician
Owner work ends where the meter begins. Book the visit once the free checks are exhausted, or immediately if the evidence already points at the compressor itself. Call immediately, and unplug the cabinet first, if you smell burning, see oil around the compressor, or hear a hiss with a sharp smell.
