I have a frigidaire glass top stove. The eyes on top work perfect, no problems. As for the oven it's a different story. I turn the oven on to preheat and it says Err. It will act as if it's going to preheat but, then the err pops up and it starts losing heat. The oven will have heat in it but, I then have to unplug the stove and plug it back in for even the eyes to be turned on. I need someone to fix it. Does anyone know of someone that can fix it at my house for a decent price??
