The short answer for the NPGB models
On the Alcove NPGB refrigerator models, a cabinet that runs but will not get cold leads with an evaporator fan that has stopped turning rather than with the cause the brand-generic article opens on. The spine for the NPGB 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
- It recovers overnight and loses ground during the day — A pattern that tracks the room rather than the machine, and worth noticing before anything is dismantled.
- 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.
- 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 NPGB family
- An evaporator fan that has stopped turning — The fan is what turns a cold plate into a cold cabinet. Without it the air stratifies, and the compartment furthest from the evaporator warms first. Ranked first here.
- 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. 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 an evaporator fan that has stopped turning; 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
- Listen at the freezer for the fan, then open the door and listen again — First: On most cabinets the door switch cuts the fan. If the sound changes, the fan is alive.
- Put a thermometer in a glass of water on the middle shelf overnight — Second: 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 — Third: Heat there means the cycle is working and the heat has nowhere to go; cold there means it is not working at all.

Safety
Nothing comes off this cabinet until it is unplugged or its breaker is switched off — a capacitor holds a charge after the power is gone, and a fan inside can start without warning. Never defeat a door switch to keep a fan running while you look: it is there to stop a blade turning next to your hand. A refrigerator holds food 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.
