^^^ That sounds correct to me. It's been so long since I changed both of those valves, I really forget which I did first and it didn't solve the problem. Since the pilot won't "flare" from Pilot to Heater, sounds like Thermostat (the one with the Knob) is indeed the point of failure. I'm thinking that's the one I changed first, then had to go back and get the other. Could have been providential to replace both, since the mercury-charged controls started going away shortly thereafter.
And, I freely admit that I did NOT have the information that's available now, and worked with a very incomplete (non-existent, actually!) understanding of how the oven worked.
