don't really know....but for sure...unplug it if you can do so safely....(don't want to shock yourself don't pour water on it if plugged in) I would then use my fire extinguisher if I had one, or maybe throw a big pot over it to cut off the oxygen supply or maybe just run out of the house and call the fire department. Don't know how big the flames would be. I had a dryer once where the lint somehow caught on fire...so when I opened the door...there was the flame....I yelled and slammed the door shut again. Thankfully, the fire extinguished itself. good thing.(maybe the wet clothes?) ..because I just stood there thinking what to do. Housefires have been started by this happening.
