The short answer
A cabinet that will not cool on an X refrigerator usually comes down to heat it cannot get rid of rather than cold it cannot make: a box wedged into a locker or a packed boot has nowhere to send the heat the condenser pulls out. The order that follows puts the likeliest and cheapest causes first, and it is the order worth working in rather than starting with the part that sounds most serious.
What you actually observe
- The outside of the cabinet near the compartment is warm to the hand — Normal while it works hard; only a concern when the surface stays hot and nothing cools.
- 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 is silent and the display shows nothing at all — NEAR MISS: that is a dead supply or a blown plug fuse, and it belongs on the will-not-start reading of this fault, not here.
- Body: No two X listings share a base number, so each one in the table is a distinct machine rather than a revision of its neighbour.
What causes it on the X platform, in likelihood order
- 1. Frost on the evaporator plate — Frost builds quietly over weeks, especially on a unit opened often in humid air. By the time an owner notices the temperature, the plate is wearing a coat. Airflow ranks higher on X than on a tighter roster: X50 has far more heat to reject than X9, and the same blocked grille costs it more.
- 2. 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. It sits second here rather than first because the cause above it is cheaper to rule out, not because this one is rarer.
- 3. Blocked heat rejection at the condenser — Clearance is the specification nobody reads.
- 4. What was put in and how warm it was — Nothing in this class has the capacity to pull a full box of room-temperature drinks down quickly.
The order to work in on this platform
- 1. Look at the plate for frost thickness — A coated plate is both the symptom and the cause; empty and defrost before judging anything else.
- 2. 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.
- 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
Isolate before you open anything. Unplug the appliance or switch off its breaker, and remember that a capacitor can hold a charge after the power is off. Never defeat the fuse in a DC plug to keep a unit running, and never pierce or cut a refrigerant line to see whether there is charge in it.

When to call a technician
Call once the supply, the airflow and the seal are all clean and the cabinet still will not fall. Call immediately if you see oil around the compressor or smell anything burning: oil outside the tubing means the sealed system is open, and every hour it runs after that costs more to put right.
