The short answer
On an XS refrigerator, a cabinet that will not cool is most often the lid rather than the machine: a gasket that no longer clamps lets warm air in faster than a small compressor can take it back out. The causes below are in likelihood order, cheapest first; working down that order costs less than starting with the part that sounds most alarming.
What you actually observe
- It cools on mains power but not from the vehicle socket — That isolates the fault to the DC supply path and nothing else.
- The panel is lit and the set temperature is displayed, but nothing inside is cold — The control has power and thinks it is working. That points at the supply to the compressor, not at the control.
- The compressor starts, runs a short while, then stops and starts again — Short cycling like this is the signature of a supply the controller keeps rejecting.
- It cools, but the contents are icing up instead — NEAR MISS: the box is over-cooling, which is the ice-production page, not this one.
- Body: With three listings in the XS table, quote the full model number when ordering anything: the differences between them are exactly the differences that matter to a parts counter.
Ranked causes on these XS models
- 1. The DC supply and its protection setting — The controller measures what the socket delivers under load and shuts the compressor down before the vehicle battery drops too far. Everything else about the unit is fine. It leads on XS because the three listings differ in capacity rather than in how they are fed, so the supply is the one thing the whole roster has in common.
- 2. Load, set point and how often it is opened — The set point matters as much as the load. Second here because it costs nothing to ask, while the cause above it explains more of what owners report on XS.
- 3. Nowhere for the heat to go — A compressor cooler moves heat out through a grille that needs moving air.
- 4. Frost on the evaporator plate — Frost builds quietly over weeks, especially on a unit opened often in humid air.
Check in this order on the XS platform
- 1. Run it from a known-good supply for a while — Swapping supplies separates the whole DC path from the appliance in one move, with no tools.
- 2. Read the set point and note the last load — Confirm what was actually asked of it before suspecting the machine.
- 3. Pull it into open air and clear the grille — Free the vent faces, wait, and feel whether the temperature starts falling.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Treat the DC lead as a live circuit even when the unit looks dead, keep the fused plug intact rather than bypassing it, and never cut into the sealed refrigerant circuit: it is licensed work and the tools to do it safely are not owner tools. Where a step below depends on which XS listing you own, the table above is the reference; nothing here is written from a model outside it.

When to call a technician
The line is the sealed system and the compressor module. Everything before it is an owner check that costs a few minutes; everything from there needs a technician, and a unit that keeps cutting out on a clean supply has already crossed it.
