AdamMH How's your electrical knowledge?
I have a degree in Electrical Engineering so I'm ok. I have fixed my washer, dryer, dishwasher and other things, but never an oven. If it was newer I might pull it apart, but it's got to be at least 30 years old. Pretty sure it was included with the house and we are not the original owners.
Even if I figure out what part is bad, I don't know that I could figure out what part number to buy because there is no serial # or even model # on this thing.
