The short answer for the NPYYN models
On the Alcove NPYYN refrigerator models, a cabinet that runs but will not get cold leads with the room the cabinet is working against rather than with the cause the brand-generic article opens on. The spine for the NPYYN family holds one model code only, so nothing below has to be qualified by which variant you own.
What you observe on these models
- The freezer is holding but the fresh-food side is not — One compartment right and one wrong points at air movement between them rather than at cold production.
- 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.
- 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 NPYYN family
- The room the cabinet is working against — Where the cabinet lives decides how hard it must work. A room that swings warm in the afternoon will produce a cabinet that is fine in the morning and losing by evening. Ranked first here.
- A condenser coil that cannot shed its heat — A coil blanketed in dust cannot dump the heat it collects, so the refrigerant never gives up enough of it to cool anything. It is also among the cheapest faults on this list to put right. Second.
- A sealed-system or compressor fault — The expensive end: refrigerant loss, a restriction, or a compressor that turns without compressing. It is ranked last because it is genuinely the least common of the causes here.
- Body: The cause that moves up on these models is the room the cabinet is working against; 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
- Put a thermometer in a glass of water on the middle shelf overnight — First: It reads the cabinet rather than the door, and it separates a real fault from a door that is opened often.
- Put a hand on the condenser coil and on the cabinet sides — Second: Heat there means the cycle is working and the heat has nowhere to go; cold there means it is not working at all.
- Pull the cabinet away from its surround and run it in the open — Third: If it starts gaining ground in open air, the installation is what needs attention, not the machine.
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
If every check above comes back clean, the remaining answer is a sealed-system or compressor fault, and that is the one that needs a technician rather than an afternoon. Call immediately, and unplug the cabinet first, if you smell burning, see oil around the compressor, or hear a hiss with a sharp smell.
