Start here
On an Alpicool refrigerator in the K family, a cabinet that will not hold temperature comes back most often to a cabinet loaded past its vents. The brand-generic page opens elsewhere, and the ranking below says which cause moved and what moved it. Most of what follows can be settled without opening anything; only the last item is a service call.
What this looks like on a K unit
- Food at the front is warmer than food at the back — A vent blocked by the load will do exactly this.
- The cabinet is warm but the unit is clearly running — The compressor is audible; the air inside is not cold.
- Frost builds as a sheet on the back wall — A sheet rather than the usual light dusting is an airflow story.
- One compartment holds and the other does not — Cold being made but not moved looks exactly like this.
- The unit never cycles off — Continuous running without reaching temperature is the same fault seen from outside.
- More than one K unit shows the same thing — With 2 builds under this key, the same behaviour across two of them points at the family rather than at one machine.
- 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 K 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 door seal that no longer closes on the cabinet — It sits behind the lead here. Warm wet air arrives continuously, and the unit answers by running continuously.
- 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 what this page's model table shows about how many builds sit under this key.
Check in this order, and why
- Look at whether the shelves are packed against the vents — This costs nothing to test and is ruled out faster than anything else on the list.
- Run a hand along the seal line with the door shut — Cold escaping at a point is warm air arriving at the same point.
- Check that the condenser fan is turning while the compressor runs — A clean coil with no air across it looks identical to a blocked one from inside the cabinet.
- Look for oil traces at the compressor — Oil outside the tubing means the system is open and the checks above no longer apply.
- Body: Read the plate before starting: the K pair are one step apart, and a check aimed at the wrong member wastes the visit rather than the minute.
Safety first
Safety
Power off first, every time. Unplug the appliance or switch off its breaker before removing a panel, since a capacitor can hold a charge after the power is off. Do not tape or bridge the door switch to keep a fan running while you look. An interlock that is defeated is a blade that turns while a hand is in the cabinet. 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 on these models is the point where a check needs a panel off or a tool you do not keep. 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.
