If you dont know the particular details, then please tell of any "fire-starter" electric circuits out there in consumer goods?
Looking objectively, a short circuit CANNOT start a fire unless there is something to pick it up locally. Nothing in the circuit is combustible (not even the working fluid) and the circuit always fails in the open circuit mode. The fuse or the circuit breaker might or might not have failed but that is far less important. The failed fridge/Freezer might have ignited some paper or clothes and INITIATED the fire.
Here in India I see most Fridge/Freezers use polystyrene foam as insulation; that is real DANGEROUS. That can set the fridge on fire. And even if you spot that within 30 seconds, it is tough to control. What kind of insulations are common over there?
Even if the insulation is enclosed (not openly visible) by other plastics, it is clearly not sufficient.
In India a large number of fires in buildings are caused by electrical short circuits- but that is only doing the simple job of lighting a match. Perhaps for every ten thousand short circuits, one building gets gutted. Most common points of short circuits are switches, relays, junction boxes, fuses and other connection points. Short circuit does not take place in the middle of the conduit. I had some problem with my air conditioner and I had to pull out the cable and discovered that the insulation has melted much over the area (but no fire and the fuses were getting blown: that was the early symptom).
In congested areas (in all big cities in India) the fridge is a designer piece and is used as a furniture and if the insulation catches fire, there is no going back. You should not waste time trying to put out the fire.
Of course I do not know the particular details but almost all electrical circuits kept in close proximity with books, clothes and similar stuff deserves greater respect. And actual circuit details or CE markings does not really matter when the device fails.
