I've got a GFCI outlet in the bathroom that controls 3 other outlets, the other bathroom and two outside outlets. The other night, during the middle of the night, the GFCI tripped. A hair dryer was plugged in but it was turned off at the time, 3A approx. The Christmas lights were plugged in to one of the outside outlets, but they were turned off. Nothing else was connected. I have not been able to reset the GFCI. I replaced it with a new GFCI last night. It still will not reset. Any ideas? Thanks.
