Had two domestic refrigerator fires over the last month; both during-/shortly after power outages
(courtesy of our power utility; a good argument against state-owned enterprises in Africa...).

Both fires originated behind/below the refrigerators; i.e. up from the compressor void.
I suspect the power spikes/brownouts somehow either nuke the limited electronics there,
or perhaps the abrupt power cut catches the compressor on a power stroke, meaning it restarts against some form of resistance (drawing more Amps).

Any technical info on domestic refrigeration's susceptibility to power outages would be appreciated.
