Start here
On the Alpicool DD 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, DD40, so everything below applies to one build rather than to a range of them.
The observables on these models
- 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.
Ranked causes for these models
- The setpoint, the units, and the control's own modes — First. Controls get changed by accident far more often than they fail. A mode selected from a menu, a display left in the other unit, a button pressed by a stacked load: each gives a cabinet that is doing exactly what it was told and nothing that the owner wanted. The record holds only DD40, 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, 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. 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
- Read the panel, then set it deliberately — Confirm the unit it is displaying in, take it off any economy or protection mode, and set it where you actually want it. Then leave it alone for a few hours, because judging a cabinet mid-pulldown tells you nothing. On DD40 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.
