The short answer for this family
For the Alpicool NX family, a cabinet that will not hold temperature is usually a control board that is not calling for cooling rather than anything deeper in the machine. That is not where the brand-generic article on this symptom starts, so a reader arriving from it should expect a different order here. The first checks below need no tools and no panel off, and they remove most of this list between them.
What the owner sees
- One compartment holds and the other does not — Cold being made but not moved looks exactly like this.
- Frost builds as a sheet on the back wall — A sheet rather than the usual light dusting is an airflow story.
- The cabinet is warm but the unit is clearly running — The compressor is audible; the air inside is not cold.
- Food at the front is warmer than food at the back — A vent blocked by the load will do exactly this.
- The display looks normal and nothing runs — Power present and no compressor is a different problem from a compressor that runs and fails.
- A NX unit of a different size behaves identically — That is what a shared build looks like: the members of this ladder differ in scale rather than in arrangement.
- NEAR MISS — only the ice has stopped — Ice can stop for reasons that have nothing to do with cabinet temperature; that is the ice page.
Causes, most likely first on the NX family
- A control board that is not calling for cooling — It is where this family starts. It is the cause that explains a machine which is completely silent but has power.
- A failed evaporator fan motor — Second on this family. It produces a warm cabinet with no frost sheet to show for it, which is how it separates from the airflow cause.
- A temperature sensor reading wrong — Third. The control believes the cabinet is colder than it is and simply stops asking for cooling.
- A sealed-system leak or a failed compressor — Ranked last. It is the least likely cause on this list and the only one that cannot be checked from outside.
- Body: The brand-generic article on this symptom opens on a frosted evaporator blocking the air path. Here it does not: a control board that is not calling for cooling has moved above it, and a frosted evaporator blocking the air path has moved down the list. What moved it is how this family is laid out across the entries in its own table.
Check in this order, and why
- Listen for a start attempt at the back — No attempt at all moves the question from the cold side to the control.
- Listen for the evaporator fan with the door switch held closed — No fan with a clean evaporator separates the two likeliest causes before a tool comes out.
- Check whether the unit ever calls for cooling at all — Silence with a healthy display is a reading problem, not a mechanical one.
- Feel whether the condenser ever gets warm during a run — A coil that never warms while the compressor runs points at the sealed system.
- Body: One order serves the whole NX ladder. The members differ in scale rather than in arrangement, so the sequence below does not need a per-model variant.
Before any panel comes off
Safety
Isolate the unit first. Unplug it or switch off its breaker before any panel is removed, because a capacitor can hold a charge after the power is off. Leave the door switch wired as it is: it cuts the fan when the door opens for a reason, and defeating it puts a hand near a blade that is still able to turn. The sealed system is out of scope for every check on this page. If a step would mean opening it, the step is a service call instead.

When to call a technician
What separates the two halves of this list is access, not difficulty. Work down the checks above first; they cost minutes and they remove most of this list. Call once they have all come back clean, because what is left is a sealed-system leak or a failed compressor, and that is the one cause here with no owner-side check at all. Skip the rest of the list and call if the unit is tripping protection repeatedly. A circuit that keeps opening is telling you something the checks above cannot.
