Whirlpool Range (GY396LXGB4) has been getting PF when starting the Bake cycle...never when using the broiler for the last several months....just hit START and the eror would clear and bake would work...recently this begin happening several times during the pre-heat cycle but would bake after pre-heat. Yesterday it quit altogether...tried to bake but the START key would not work...unplugged from outlet and replugged then start key worked and everything appeard to be working....preheat cycle etc, but oven would not heat...nor would broiler. Display works fine and so does the stove...error code shows -F1- E1....this is a checksum error...does this mean a new controller?

Thanks
