The short answer
A cabinet that will not hold temperature on the Alpicool DC family points first at a temperature sensor reading wrong. Anyone who has already worked the brand-generic article can skip its opening: this family does not rank the causes the same way. Of the causes listed here, all but one are owner-checkable, and a dust-packed condenser is the one worth ruling out immediately after the first.
What you observe
- 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 DC 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 DC family
- A temperature sensor reading wrong — It is the first thing to rule out on these models. The control believes the cabinet is colder than it is and simply stops asking for cooling.
- A dust-packed condenser — It follows the lead on these models. The run time climbs first and the temperature follows, so it is gradual rather than sudden.
- A door seal that no longer closes on the cabinet — It comes after the two above it. It is the cause that gets worse in humid weather and better in dry, which is a useful tell.
- 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: The brand-generic article on this symptom opens on a frosted evaporator blocking the air path. Here it does not: a temperature sensor reading wrong 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
- Check whether the unit ever calls for cooling at all — Silence with a healthy display is a reading problem, not a mechanical one.
- Pull the unit out and look at the condenser coil — Dust packed between the fins is heat that cannot leave, and it comes straight back into the cabinet.
- Run a hand along the seal line with the door shut — Cold escaping at a point is warm air arriving at the same point.
- 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: Confirm which of the two DC models you have first. The order below holds for both, but the access differs enough that guessing costs time.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Sheet-metal edges behind a panel cut, and a compressor housing stays hot long after a run. Gloves for the first, patience for the second. 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
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 where the list stops being owner work. Call straight away, without working down the list, if you smell burning or see oil outside the tubing at the back: oil outside the tubing means the system is open, and every hour it runs after that costs more to put right.
