The short answer
On the Alpicool KI refrigerator a complaint that reads as "it runs but nothing is cold" is far more often a condenser fan that has stopped than a failed compressor. The model record for this family is a single code, KI65, so everything below applies to one build rather than to a range of them.
What you observe
- It never stops running — A healthy cabinet cycles. One that runs from morning to night is one that is never reaching the number it was set to.
- It is plainly running, and nothing inside is cold — The compressor note is there and the panel is lit; the contents disagree with both.
- Frost has banked up on the cold plate — A sheet rather than a light dusting, often heavier at one end than the other.
- NEAR MISS — it is cold but there is water underneath it — A cabinet that holds temperature and leaks is the water-leak page, not this one.
Causes, most likely first on this family
- A condenser fan that has stopped — First. Rejecting heat is half convection and half whatever the fan moves, so losing the fan halves the machine without stopping it. The signature is a compressor running hot and long, warm still air at the grille, and a cabinet that gets part of the way down and stalls. The record holds only KI65, so this check is the whole of the family's exposure to that cause.
- Heat that cannot leave the condenser — Second. A compressor refrigerator does not make cold, it moves heat, and only into air free to carry it away. Boxed into a cupboard, pushed against a wall or packed round with luggage, it breathes back the air it has just warmed, runs without stopping and never reaches setpoint.
- A loss in the sealed system — Last, always. It is the rarest of these causes and the only one that cannot be touched without recovery equipment and a licence. What it looks like is a machine trying hard and achieving nothing: long runs, a condenser that stays lukewarm, and a cabinet that drifts back up as fast as it comes down.
- Body: With one code recorded there is no older or newer build here to tell apart. The record does not say what the numbers in the codes stand for, which is why this page reasons from what the cabinet does rather than from a specification. Where the codes differ but the layout behind them does not, the moving part is the thing to check first: a stalled condenser fan gives the same continuous running as a blocked condenser and is far quicker to confirm.
First, second, third
- Listen and feel at the vents while the compressor is running — Air should be moving and it should be warm. Still, warm air at the grille with the compressor running is the fan, not the refrigeration. On KI65 that is the whole of this step.
- Give it a hand's width on every side and run it for an hour — Watch whether the compressor starts cycling rather than running flat out. Recovery in open air is an installation verdict, not a repair.
- Body: The record holds one code for this family, so the order below is not a model matrix — it is the order in which these causes can be eliminated on the machine in front of you, cheapest and least invasive first.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Everything in the order above is done with the cabinet standing as it is, and none of it needs a panel off. Keep hands and tools away from the compressor and the tubing around it: those lines are under pressure, and a scratch that opens one turns an ordinary repair into a sealed-system job.

The line between a fix and a service call
Stop and call if the compressor runs and the coil never warms up, if the cabinet trips the circuit it is on, or if the tubing is oily or damaged. Those three are sealed-system findings, and the tools for them are recovery tools rather than hand tools. Short of that, a cabinet that fails one of the checks above is usually fixed by correcting what failed it, at no cost but the time.
