The short answer
On a TA refrigerator the usual explanation for a cabinet that will not cool is a supply problem at the socket rather than a dead compressor: the controller watches the voltage it is fed and stops cooling before it flattens a battery, and it does that with the panel still lit. Work the order below rather than the order of expense: the two cheapest checks settle most of these before a tool comes out.
What you actually observe
- 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 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 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: Where a step below depends on which TA listing you own, the table above is the reference; nothing here is written from a model outside it.
Causes, most likely first on the TA platform
- 1. Supply voltage and the battery-protection cutoff — Voltage at the plug is not voltage at the compressor. It leads on TA 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. Nowhere for the heat to go — A compressor cooler moves heat out through a grille that needs moving air. It comes second because the check above it costs nothing, where this one usually means moving the machine.
- 3. Load, set point and how often it is opened — The set point matters as much as the load.
- 4. The control module on the compressor — The small module bolted to the compressor is what starts it and sets its speed.
What to check first on these TA models, and why
- 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. Pull it into open air and clear the grille — Free the vent faces, wait, and feel whether the temperature starts falling.
- 3. Read the set point and note the last load — Confirm what was actually asked of it before suspecting the machine.
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.
