I’ve been hearing a hum come from my fridgidaire model #LGEF3043KFM for a few months now. I passed it off as the light being blown. Then this morning when baking all of the sudden I got a F10 code and I saw sparks and then smoke came from where the control board is located. The F10 kept flashing and I flipped the breaker. I waited a while and just now flipped it back on and everything seems to cut on. I haven’t actually tried to heat anything up to temperature. What would be the correct temperature sensor and control board for this model? And what could have happened?

It sounds to me like one the relay blew on the board either the bake or broil relay. At any rate you definiltey need to replace the board, I doubt the sensor was damaged but I will link both parts below.
