I suspect most "eletrical appliance" fires are damaged or otherwise
abused cables and plug/sockets rather than an actual fault with the
appliance(*). Just like most things failing a PAT on the visual
inspection rather than what the box says when the button is pressed.

(*) Note "fault" not "poor design".


There were some Hotpoint fridge/freezers a few years ago that
apparently had a problem with the wires that went out to the doors, they
would chafe, or something. Ours was similar, but not of the exact range
that suffered from the problem.
