Oh my goodness. I've read of Rowenta irons catching fire. mine blew out my power cord finally. I'd had it for years. I tossed it. I never left my iron plugged in, no matter what. I hate leaving my coffee pot plugged in. I don't use the timer for it to start coffee for me.
take it slow. did the fire dept. say what started the fire? It would serve the companies right if you could sue for damages. Good luck.
