The Tappan oven in our 1963
Tradewind is doing the same thing as reported in post #1. The pilot lights, but not the burner.
Is it the mechanism behind the oven control knob that is the culprit, OR is it thermacouple (not sure if that is the correct terminology) in the bottom of the oven?
Tappan and Magic Chefs of that era look like they might have been made by the same manufacturer.
