The short answer
Alpicool's GD family answers a cabinet that will not hold temperature in a particular order, and a temperature sensor reading wrong is at the top of it. The order below is this family's own, and it is not the order the brand-generic article sets out. Of the causes listed here, all but one are owner-checkable, and a frosted evaporator blocking the air path is the one worth ruling out immediately after the first.
What you observe
- The unit never cycles off — Continuous running without reaching temperature is the same fault seen from outside.
- The cabinet is warm but the unit is clearly running — The compressor is audible; the air inside is not cold.
- It cools in cool weather and fails in warm — A marginal heat rejection path shows itself seasonally.
- Temperature recovers for a day after a thaw — A unit that comes back after being emptied and left open has told you the cause.
- Frost builds as a sheet on the back wall — A sheet rather than the usual light dusting is an airflow story.
- No second GD unit to compare against — One model carries this key, so there is nothing in the family to cross-check — the observations below stand on their own.
- 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 GD family
- A temperature sensor reading wrong — It is the first thing to rule out on these models. The control believes the cabinet is colder than it is and simply stops asking for cooling.
- A frosted evaporator blocking the air path — It follows the lead on these models. Air stops moving before the cold stops being made, which is why the unit still sounds healthy.
- A door seal that no longer closes on the cabinet — It comes after the two above it. It is the cause that gets worse in humid weather and better in dry, which is a useful tell.
- 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 temperature sensor reading wrong has moved above it, and a frosted evaporator blocking the air path has moved down the list. What moved it is the spread of the entries this family's model table carries.
Check in this order, and why
- 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.
- Empty the unit, leave it open for a day and watch it recover — A unit that comes back after a thaw has named its own cause.
- Close the door on a sheet of paper and pull — If it slides out freely anywhere along the run, that is where warm air is arriving.
- Look for oil traces at the compressor — Oil outside the tubing means the system is open and the checks above no longer apply.
- Body: Because the GD key covers one model, the order below skips the identification step that a multi-model family needs and goes straight to the likeliest cause.
Before you open anything
Safety
Before a panel comes off, isolate the unit at the plug or at the breaker. 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. The sealed system is out of scope for every check on this page. If a step would mean opening it, the step is a service call instead.

When to call a technician
On this family the split is simple: anything reachable without removing a panel is owner work, and nothing past that is. 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. Skip the rest of the list and call if the unit is tripping protection repeatedly. A circuit that keeps opening is telling you something the checks above cannot.
