The short answer
On a TW 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 box holds a mild chill but never reaches the set point — Heat is getting in as fast as it comes out, which is a seal, a load or an airflow problem.
- 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, 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 TW roster covers six listings, TW35 through TW115, and what follows is common to all of them unless a step says otherwise.
Causes, most likely first on the TW platform
- 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. The TW ladder runs from TW35 to TW115, and the draw at the top of it is what exposes a marginal supply first.
- 2. Blocked heat rejection at the condenser — Clearance is the specification nobody reads. It comes second because the check above it costs nothing, where this one usually means moving the machine.
- 3. Ice where the cold is supposed to leave — The plate has to touch air and contents to cool them.
- 4. Lid gasket and latch — Seal faults look like weak cooling rather than no cooling.
What to check first on these TW 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. Look at the plate for frost thickness — A coated plate is both the symptom and the cause; empty and defrost before judging anything else.
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. The spread between TW35 and TW115 is wide enough that the two ends of the TW roster do not behave alike under load.

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.
