The short answer
A cabinet that will not hold temperature on the Alpicool KCF family points first at a dust-packed condenser. 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 control board that is not calling for cooling is the one worth ruling out immediately after the first.
What you observe
- 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.
- Frost builds as a sheet on the back wall — A sheet rather than the usual light dusting is an airflow story.
- Temperature recovers for a day after a thaw — A unit that comes back after being emptied and left open has told you the cause.
- It matches a unit whose plate reads close but not identical — A near match is a different family. Only the entry in this page's model table is covered here.
- 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 KCF family
- A dust-packed condenser — It is the first thing to rule out on these models. Heat that cannot leave the coil comes straight back into the cabinet.
- A control board that is not calling for cooling — It follows the lead on these models. It is the cause that explains a machine which is completely silent but has power.
- A defrost cycle that has stopped running — It comes after the two above it. It is the upstream cause of the airflow blockage rather than a separate fault.
- 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 dust-packed condenser 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
- Feel how hot the back is after a long run — A coil that is hot and dirty is a coil that is not rejecting heat.
- 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.
- Ask how long the unit stayed good after the last thaw — Days rather than weeks points upstream of the ice itself.
- 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: With one member in the family there is nothing to identify first, so the order below is driven entirely by the ranking above it.
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. Fan blades stay sharp and stay able to turn after the power is cut. Keep the interlock intact and let the fan stop on its own before reaching past it. 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 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.
