Would anyone have an idea what happened here. I have a small, electric heater in my granddaughters room. Lowes special, looks like a small fireplace. I have it plugged in to a gfi outlet. Wednesday night the gfi tripped, I reset it and used it last night. It went off again during the night but before it tripped it scorched the outlet on the hot side, black wire side. It must have cooked the gfi because it will not reset. Really scared me, could have been a fire. We used this last year with no problems and nothing has changed on the circuit. The heater is rated at 1500 / 60 hz. Would this be a problem with the heater causing this? I dont think I will use it again but worry that another heater may do the same thing. It actually started to melt the outlet. Anyone have any ideas if the heater went bad to cause this or is it a circuit problem. Thanks.
