Replaced ERC - Now What?

Started getting F1E1 error code (along with replace oven AM) on the display. The answers I got from online research, Kitchenaid, etc., was to replace the ERC part #9762794.

Did that and 15 seconds after turning on power, got the same message, F1E1. Unplugged, waited, plugged in, same message returns to display. Have tried this enough times to know something else is going on. Any help please?
