My heater was unplugged because itwas getting warm in the room and when I plugged it back in it wouldnt come back on. We have been unplugging it because it where when it was turned it might not come on so we left itturned on justunplugged. Im a single mother and got 3 girls that are cold. Please help. I know a little about electricity so I may can fix it if I know what is wrong.
