Start here
A cabinet that will not hold temperature on the Alpicool CLS family points first at a condenser fan that has stopped. 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 CLS unit
- 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 cools in cool weather and fails in warm — A marginal heat rejection path shows itself seasonally.
- The cabinet is warm but the unit is clearly running — The compressor is audible; the air inside is not cold.
- The unit never cycles off — Continuous running without reaching temperature is the same fault seen from outside.
- Condensation inside the door — Warm wet air is getting in somewhere along the seal line.
- A CLS 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 CLS family
- A condenser fan that has stopped — It leads here. It is quick to confirm because the fan is on the accessible side of the machine.
- 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 cabinet loaded past its vents — It is third on this family. It appears right after a big shop and disappears when the load comes down, which dates it precisely.
- 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 condenser fan that has stopped 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
- 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.
- 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.
- Move the load away from the outlets for a day — A unit that recovers when it is unpacked has told you the answer.
- 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 CLS 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. 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. 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 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.
