I just wanted to follow up and thank you for your help. I ordered the board Monday, it arrived the next day (on regular shipping no less!) and I swapped it out last night. Everything appears to be working as is it should now with that new control board.
It was certainly gratifying to be able to repair the oven myself and save a nice chunk of change in the process.
Thank you again for the links to the correct part and the wiring diagram, both were very helpful.
