The short answer for the NN models
On the Alcove NN refrigerator models, a cabinet that runs but will not get cold leads with a door gasket that no longer seals 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
- 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 — it cools correctly but there is water underneath — That is a drain or a supply fault. The water-leak page for this appliance is the right page.
Causes, most likely first on the NN family
- A door gasket that no longer seals — A gasket that has taken a set, or a door that no longer pulls square, lets room air in continuously. The unit answers by running continuously, and it still loses. Ranked first here.
- The cold control or the temperature setting — The cheapest cause on the list and the one most often skipped. A control that reads the cabinet wrongly stops the compressor early and everything else looks healthy. 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 a door gasket that no longer seals; 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
- Close the door on a strip of paper and pull it out at several points — First: Anywhere the paper slides free, the seal is not making contact.
- 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.
- Clear the rear vents inside and give the shelves room — Third: Blocked internal vents produce a warm front shelf and a cold back one, which is an airflow answer rather than a compressor one.
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 a sealed-system or compressor fault. Call immediately, and unplug the cabinet first, if you smell burning, see oil around the compressor, or hear a hiss with a sharp smell.
