The short answer
A cabinet that will not cool on a ZGW 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 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.
- 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: The ZGW roster is a single listing, ZGW40, so everything here applies to one build rather than to a range.
What causes it on the ZGW platform, in likelihood order
- 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. It ranks first on a one-listing platform because there is no size variation to spread the blame across: every ZGW report comes back to the same build and the same supply path.
- 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. A lid that no longer clamps — The gasket is the only thing between the compartment and the day outside.
- 4. Load, set point and how often it is opened — The set point matters as much as the load.
The order to work in on this 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. Pull it into open air and clear the grille — Free the vent faces, wait, and feel whether the temperature starts falling.
- 3. 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.
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.

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.
