The short answer
For the Alpicool CF family, a cabinet that will not hold temperature is usually a dust-packed condenser rather than anything deeper in the machine. That is not where the brand-generic article on this symptom starts, so a reader arriving from it should expect a different order here. Of the causes listed here, all but one are owner-checkable, and a temperature sensor reading wrong is the one worth ruling out immediately after the first.
What you observe
- The display looks normal and nothing runs — Power present and no compressor is a different problem from a compressor that runs and fails.
- It cools in cool weather and fails in warm — A marginal heat rejection path shows itself seasonally.
- Condensation inside the door — Warm wet air is getting in somewhere along the seal line.
- The back of the unit is hot to the hand — Heat that cannot leave the coil is heat that comes back inside.
- Temperature recovers for a day after a thaw — A unit that comes back after being emptied and left open has told you the cause.
- Advice for a CF unit does not fit yours — Check which side of the gap in the model table your entry sits on — the two groups are not laid out the same way.
- 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 CF 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 temperature sensor reading wrong — It follows the lead on these models. Nothing sounds or looks wrong, which is what makes this one slow to find.
- 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 how this family is laid out across the entries in its own table.
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.
- 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.
- 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: The gap in the CF numbering matters here: the low group and the high group are laid out differently enough that the first check is worth confirming against your own member.
Before you open anything
Safety
Isolate the unit first. Unplug it or switch off its breaker before any panel is removed, because 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
What separates the two halves of this list is access, not difficulty. 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. 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.
