The short answer
For the Alpicool ENX family, a cabinet that will not hold temperature is usually a frosted evaporator blocking the air path 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. Of the causes listed here, all but one are owner-checkable, and a door seal that no longer closes on the cabinet is the one worth ruling out immediately after the first.
What you observe
- Temperature recovers for a day after a thaw — A unit that comes back after being emptied and left open has told you the cause.
- The unit never cycles off — Continuous running without reaching temperature is the same fault seen from outside.
- 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.
- A ENX 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 — the unit is silent and the display is dark — That is a power fault, and none of the checks below apply until it has power.
Causes, most likely first on the ENX family
- A frosted evaporator blocking the air path — It is the first thing to rule out on these models. The ice builds quietly over weeks, so the owner notices the warmth long before noticing the frost.
- A door seal that no longer closes on the cabinet — It follows the lead on these models. A seal that has taken a set from being stored shut behaves differently from one that is torn.
- A control board that is not calling for cooling — It comes after the two above it. It is rarer than the mechanical causes and is diagnosed by ruling those out first.
- A sealed-system leak or a failed compressor — It ends the list. Refrigerant work is licensed work and the tools for it are not owner tools.
- Body: This family keeps the brand-generic lead, but the order behind it is not the brand's. A door seal that no longer closes on the cabinet has moved up into second place, ahead of a failed evaporator fan motor, and what moved it is how this family is laid out across the entries in its own table.
Check in this order, and why
- Empty the unit, leave it open for a day and watch it recover — A unit that comes back after a thaw has named its own cause.
- Close the door on a sheet of paper and pull — If it slides out freely anywhere along the run, that is where warm air is arriving.
- Listen for a start attempt at the back — No attempt at all moves the question from the cold side to the control.
- 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 ENX ladder. The members differ in scale rather than in arrangement, so the sequence below does not need a per-model variant.
Before you open anything
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. Anything on the sealed side belongs to a licensed technician. That line does not move because a fault is small or a part looks accessible.

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 where the list stops being owner work. Two things end the owner-side list immediately: a burning smell, and oil anywhere outside the tubing. Both mean stop and call rather than continue.
