The short answer
On a WH refrigerator, a cabinet that will not cool is most often the lid rather than the machine: a gasket that no longer clamps lets warm air in faster than a small compressor can take it back out. The causes below are in likelihood order, cheapest first; working down that order costs less than starting with the part that sounds most alarming.
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.
- 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 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 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 WH listing you own, the table above is the reference; nothing here is written from a model outside it.
Ranked causes on these WH models
- 1. Blocked heat rejection at the condenser — Clearance is the specification nobody reads. It moves up on WH because the three listings grow the cabinet without growing the vent face in proportion, so the largest of them is the tightest for air.
- 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. Everything else about the unit is fine. It sits second here rather than first because the cause above it is cheaper to rule out, not because this one is rarer.
- 3. 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.
- 4. A lid that no longer clamps — The gasket is the only thing between the compartment and the day outside.
Check in this order on the WH platform
- 1. Pull it into open air and clear the grille — Free the vent faces, wait, and feel whether the temperature starts falling.
- 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. 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
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.
