The short answer for the NPYXU models
On the Alcove NPYXU refrigerator models, a cabinet that runs but will not get cold leads with a condenser coil that cannot shed its heat rather than with the cause the brand-generic article opens on. The spine for the NPYXU family records one model code, which is to say the family and the machine are the same thing.
What you observe on these models
- 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.
- Both compartments are warm and the unit never stops — Continuous running without result is the signature of heat that cannot leave the cabinet.
- 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 NPYXU family
- 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. Ranked first here.
- 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. 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 condenser coil that cannot shed its heat; 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 hand on the condenser coil and on the cabinet sides — First: Heat there means the cycle is working and the heat has nowhere to go; cold there means it is not working at all.
- Listen at the freezer for the fan, then open the door and listen again — Second: 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 — Third: It reads the cabinet rather than the door, and it separates a real fault from a door that is opened often.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before any panel is removed. The charge in a capacitor outlives the switch, and the evaporator fan has no warning before it runs. Leave the door switch wired exactly as it is, and leave the refrigerant side alone — that is licensed work. Move perishables to a cooler with ice: a freezer holds food safely 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.
