The short answer
On the Alpicool G refrigerator a complaint that reads as "it runs but nothing is cold" is far more often ambient heat beyond what the cabinet can pull down than a failed compressor. The five codes in this family share the G prefix and differ only in what follows it, running from G15 to G65. Work the order below rather than the order that occurs to you: the first two checks need no tools at all.
What you observe
- 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.
Causes, most likely first on this family
- Ambient heat beyond what the cabinet can pull down — First. Any refrigerator holds only so many degrees below the air around it. In a closed vehicle in summer or an unheated garage, a healthy cabinet can run all day and still read warm — the fault is where it stands. The same check covers everything from G15 to G65; the record gives no reason to treat those codes differently here.
- 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 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: Five codes, one G prefix, G15 at one end and G65 at the other. Nothing recorded here rates these codes against an ambient, so the first question is not what has failed but what the cabinet is being asked to do — a machine that cannot win against the room it stands in is not a machine with a fault.
First, second, third
- Judge it against the air around it, not against the setpoint — Measure the room, then the cabinet. A unit sitting well below a hot room is working; one sitting level with a cool room is not. Identical on every code from G15 to G65.
- Pull it clear and give the condenser open air — Leave it running in the open for an hour and watch whether the compressor starts cycling instead of running continuously. A cabinet that recovers in open air has an installation fault, not a refrigeration fault.
- Body: Nothing in the record separates these codes by arrangement, so the same two checks apply to all of them, ordered by what each one rules out. Do them in this order: each step is only meaningful once the one above it is clean.
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.

Reference| Model number | Family key |
|---|---|
| G15 | alpicool:refrigerator:g |
| G20 | alpicool:refrigerator:g |
| G22 | alpicool:refrigerator:g |
| G55 | alpicool:refrigerator:g |
| G65 | alpicool:refrigerator:g |
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.
