So this is how my week started:
Fortunately the appliance parts place ships fast. Unfortunately, what should have been a 15 minute job turned into nearly an hour after the yellow wire slipped back behind the stove, forcing me to pull the thing out to get to the access panel on the back. Then I had to deal with nineteen years of food debris and other stuff that had fallen between the stove and the cabinet. 
But everything is working now.
