So first context: I'm not OP, and as a matter of record the Ghost Ship fire was not caused by a fridge compressor. Electrical appliance is the most likely cause but the ATF investigators ruled the fridge compressor out. That being said, sparking near relay blades is common enough and same for sketchy wire bonding. It's not a failure mode of the compressor as much as the relay or the wiring is true, but no other appliance is wired like that and turning on and off autonomously in the average household except maybe AC which are usually less modular and wired at the factory to higher standards than some old fridge or a repaired unit.
