Start here
A cabinet that will not hold temperature on the Alpicool NLD family points first at a cabinet loaded past its vents. Anyone who has already worked the brand-generic article can skip its opening: this family does not rank the causes the same way. Most of what follows can be settled without opening anything; only the last item is a service call.
What this looks like on a NLD unit
- Condensation inside the door — Warm wet air is getting in somewhere along the seal line.
- Food at the front is warmer than food at the back — A vent blocked by the load will do exactly this.
- One compartment holds and the other does not — Cold being made but not moved looks exactly like this.
- The back of the unit is hot to the hand — Heat that cannot leave the coil is heat that comes back inside.
- The display looks normal and nothing runs — Power present and no compressor is a different problem from a compressor that runs and fails.
- A NLD 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 — water under the unit and normal temperature — A leak with a cold cabinet is the leak page, not this one.
Causes, most likely first on the NLD family
- A cabinet loaded past its vents — It leads here. It costs nothing to test and is ruled out faster than anything else on this list.
- A control board that is not calling for cooling — It sits behind the lead here. The display behaves and the compressor never starts, which is a different picture from a unit that runs and fails.
- A condenser fan that has stopped — It is third on this family. The compressor runs hot and may cut out on its own protector, giving an intermittent picture.
- A sealed-system leak or a failed compressor — Last on this family. Oil at the compressor or a coil that never gets warm are the two signs that take you straight here.
- Body: The brand-generic article on this symptom opens on a frosted evaporator blocking the air path. Here it does not: a cabinet loaded past its vents has moved above it, and a frosted evaporator blocking the air path has moved down the list. What moved it is the shape of this family's numbering rather than anything about the brand as a whole.
Check in this order, and why
- Move the load away from the outlets for a day — A unit that recovers when it is unpacked has told you the answer.
- Establish whether the compressor ever starts — A display that behaves and a compressor that never runs is a different picture from a unit that runs and fails.
- Watch whether the compressor cuts out on its own after a long run — Its own protector tripping points at heat rejection, not at the cabinet.
- 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 NLD ladder. The members differ in scale rather than in arrangement, so the sequence below does not need a per-model variant.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel; 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
The line here is drawn at the first check that cannot be made from outside the cabinet. 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 only item on this page that cannot be judged from outside the cabinet. 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.
