Thank you for your question and I understand your concern.
I assume you received part #9782435 for the microcomputer board/power board.
I added an image below with the information about the F1/E3 fault code. I you're not able to correct the issue using the information in the image below; I strongly suggest calling a service technician to properly diagnose and repair your range.
I hope this is helpful. If I may be of further assistance as more details become available, please reply to this post.
