The short answer
On a WTW 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 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.
- 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.
- 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: The WTW roster covers two listings, WTW20 through WTW25, and what follows is common to all of them unless a step says otherwise.
Causes, most likely first on the WTW platform
- 1. Nowhere for the heat to go — A compressor cooler moves heat out through a grille that needs moving air. It moves up on WTW because the two listings share a cabinet layout, and that layout decides where the heat has to go.
- 2. Lid gasket and latch — Seal faults look like weak cooling rather than no cooling. Second on WTW: it is as common as the cause above it but takes longer to prove, so it is checked afterwards.
- 3. 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.
- 4. Load, set point and how often it is opened — The set point matters as much as the load.
What to check first on these WTW models, and why
- 1. Pull it into open air and clear the grille — Free the vent faces, wait, and feel whether the temperature starts falling.
- 2. Close the lid on a sheet of paper and pull — A sheet that slides out with no drag marks the part of the seal that is not clamping.
- 3. 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.
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. No two WTW listings share a base number, so each one in the table is a distinct machine rather than a revision of its neighbour.

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.
