frigidaire stove ?

I recently bought a house that came with a frigidaire self cleaning stove and the control touch pad makes a cracking sound or almost a sizzling sound at all times. everything works ok but am concerned about this sound. anyone heard of this?? almost forgot the model # is cfef372as4

thanks, steel

i had such a problem and was told fridgidaire has issues with the board not being soldered well. I had to take it into a repair shop and for $60 they re floated the board and things have worked great since.
Hope this helps!!
