As if a legal battle with Samsung wasnt bad enough, Dyson has to put out a fire within its own walls now. The companys issued a voluntary recall for the heater versions of its Air Multiplier fans because a few have short-circuited and caught alight, as spotted by Reuters. The entire sales run (around 1,000,000 units, as Dyson tells it) will be recalled after reports that four of them malfunctioned, resulting in contained burning inside the machines.
