The short answer for the NPWHC models
On the Alcove NPWHC 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 NPWHC family names exactly one model, which makes this a page about one cabinet rather than about a range.
What you observe on these models
- 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.
- The outside of the cabinet is hot to the hand — Warm sides are normal on a compact unit; hot sides with a warm interior say the heat is not getting away.
- 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 NPWHC family
- The room the cabinet is working against — A compact cabinet is rated for an ordinary room. In a garage, a sun-facing corner or an unventilated closet it can be asked for more than it was built to give. Ranked first here.
- The enclosure the cabinet is standing in — Every cabinet has to dump its heat somewhere, and a fitted recess with a closed back gives it nowhere to go. The unit then runs without ever gaining ground, which is exactly what this symptom looks like. Second.
- A sealed-system or compressor fault — A cabinet that runs without ever cooling can be a dead sealed system, but it is the rarest cause on this list and the only one that ends in a licensed repair.
- 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.
- Pull the cabinet away from its surround and run it in the open — Second: If it starts gaining ground in open air, the installation is what needs attention, not the machine.
- Listen at the freezer for the fan, then open the door and listen again — Third: On most cabinets the door switch cuts the fan. If the sound changes, the fan is alive.
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 once the owner-side checks are clean, because what is left is a sealed-system or compressor fault, and that is licensed work rather than a weekend job. Call immediately, and unplug the cabinet first, if you smell burning, see oil around the compressor, or hear a hiss with a sharp smell.
