The short answer for the NPYXX models
On the Alcove NPYXX refrigerator models, a cabinet that runs but will not get cold leads with airflow blocked by a frosted evaporator 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
- Food is spoiling sooner than it used to — A refrigerator holds food safely at 40 degrees Fahrenheit, 4 degrees Celsius, or below. Above that, the change shows in the food before it shows anywhere else.
- The cabinet is warm but you can hear it running — The compressor hum is there. The air inside is not cold, and it has not been for a while.
- A sheet of frost has built on the back wall of the freezer — Not the usual light dusting — a solid layer that has been growing for weeks.
- NEAR MISS — the cabinet is silent and nothing is cold — That is a no-power or start-relay fault, and it belongs on a different page than this one.
Causes, most likely first on the NPYXX family
- Airflow blocked by a frosted evaporator — Ice on the evaporator is an insulator and a wall at the same time. It stops the air path first, which is why the fresh-food side usually warms before the freezer does. Ranked first here.
- The cold control or the temperature setting — Settings get moved. Before anything comes apart, the setting is worth reading rather than assumed, because a wrong one reproduces this symptom exactly. Second.
- A sealed-system or compressor fault — A leak, a blockage, or a compressor that no longer pumps. Last, and that is the point of the order: it is the least likely of these and the only one that is not owner work.
- Body: The cause that moves up on these models is airflow blocked by a frosted evaporator; what moves down to make room for it is the enclosure the cabinet is standing in, which is where the brand-generic article for this symptom opens.
Check in this order, and why
- Open the freezer and look at the rear panel for ice — First: A frost sheet names a defrost fault in one look, and rules it in or out before anything is dismantled.
- Read the temperature setting the cabinet is actually on — Second: It costs nothing to read, and a setting that has been nudged reproduces the whole symptom.
- Close the door on a strip of paper and pull it out at several points — Third: Anywhere the paper slides free, the seal is not making contact.
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 a sealed-system or compressor fault — 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.
