The short answer for this family
On an Alpicool refrigerator in the CL family, a cabinet that will not hold temperature comes back most often to a control board that is not calling for cooling. The brand-generic page opens elsewhere, and the ranking below says which cause moved and what moved it. The first checks below need no tools and no panel off, and they remove most of this list between them.
What the owner sees
- 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.
- 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 back of the unit is hot to the hand — Heat that cannot leave the coil is heat that comes back inside.
- More than one CL unit shows the same thing — With 3 builds under this key, the same behaviour across two of them points at the family rather than at one machine.
- NEAR MISS — only the ice has stopped — Ice can stop for reasons that have nothing to do with cabinet temperature; that is the ice page.
Causes, most likely first on the CL family
- A control board that is not calling for cooling — It is where this family starts. It is the cause that explains a machine which is completely silent but has power.
- A door seal that no longer closes on the cabinet — Second on this family. It is the cause that gets worse in humid weather and better in dry, which is a useful tell.
- A temperature sensor reading wrong — Third. The control believes the cabinet is colder than it is and simply stops asking for cooling.
- A sealed-system leak or a failed compressor — Ranked last. It is the least likely cause on this list and the only one that cannot be checked from outside.
- Body: The brand-generic article on this symptom opens on a frosted evaporator blocking the air path. Here it does not: a control board that is not calling for cooling 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
- 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.
- Run a hand along the seal line with the door shut — Cold escaping at a point is warm air arriving at the same point.
- Put a thermometer in the cabinet and compare it with the display — A control that believes it is cold stops asking for cooling and nothing sounds wrong.
- Look for oil traces at the compressor — Oil outside the tubing means the system is open and the checks above no longer apply.
- Body: The CL members share a layout, so this order holds across the ladder; what changes with size is how long each check takes, not which check comes first.
Before any panel comes off
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. 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 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 one cause here with no owner-side check at all. 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.
