On the Alpicool AL refrigerator a complaint that reads as "it runs but nothing is cold" is far more often the setpoint, the units, and the control's own modes than a failed compressor. The model record for this family is a single code, AL42, so everything below applies to one build rather than to a range of them.
The observables on these models
- It is plainly running, and nothing inside is cold — The compressor note is there and the panel is lit; the contents disagree with both.
- 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 pulls down overnight and gives it all back by the afternoon — That pattern points at the room and at the seal, not at the refrigeration.
- NEAR MISS — it is silent and dark — Nothing lit, nothing running: that is a power or start fault and belongs on a different page from this one.
Ranked causes for these models
- The setpoint, the units, and the control's own modes — First. A panel reading in the other temperature unit, an economy or protection mode left on, or a setpoint nudged by something leaning on it all present as a cabinet that is not cold enough. A refrigerator holds food safely at 40 °F (4 °C) or below; a control only cools to the number it was given. The record holds only AL42, so this check is the whole of the family's exposure to that cause.
- The supply the cabinet is running from — Second. Starting a compressor is the hardest thing the cabinet does all day, and it does it against whatever the socket can deliver at that instant. Feed it through a long lead or a worn outlet and the voltage dips, the control drops out rather than risk the motor, and it goes round again. Lights on, nothing cold, no fault stored.
- A loss in the sealed system — Last in every ordering: the least common of these and the only one that is not owner work. The pattern is a compressor running on while the condenser never gets properly hot — it is trying, with nothing left to move the heat with.
- Body: With one code recorded there is no older or newer build here to tell apart. What the trailing block of each code measures is not recorded here, so treat the models as one platform unless the part in front of you plainly differs. When the record cannot tell you which control a given code carries, you start at the panel: the settings are the one part of this fault that costs nothing to rule out and that no amount of dismantling will reveal later.
The order to work in
- Clear every mode and set the temperature deliberately — Check which unit the panel is displaying, cancel any economy or protection setting, then leave the cabinet alone for several hours before judging it. On AL42 that is the whole of this step.
- Plug it into a different socket, directly — No adaptor, no extension, nothing else on the same outlet. A machine that cools properly on the new socket has told you the fault was never inside it.
- 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 any panel comes off
Safety
Unplug the cabinet or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. If the cabinet has been laid on its side or its back, stand it upright and leave it standing for some hours before running it. Leave the sealed system alone: refrigerant work is licensed work and needs recovery equipment, not hand tools.

Where owner work stops
The line is the sealed system and it is the same on every model in this family: everything above it is owner work, and nothing below it is. Call when the cabinet has passed all of the checks above and still will not hold, when the compressor cuts out on its own protection within minutes of starting, or when you find oil on the tubing. Keep perishable food out of it while you wait rather than gambling on the next few hours.
