I have a Jenn-Air Electric Range, model SVE47100W. The oven heating elements burnt during baking, the clock display went dark and the small fan assembly (part AP376750) started to run continuously. The fan wouldn't stop even after I unplugged the burnt heating element. I then disconnected the power connector of the fan, plugged in the power, then I heard a strange sound whenever the oven door is opened.

I know I have to replace the heating element since it is damaged. Control panel too maybe, but how do I find out what other parts need to be replaced? Thank you!
