I'm having the same problem with my 85' sovereign with 4 burner magic chef oven. I changed my safety valve with no luck so now I'm looking for a thermostat and they are VERY hard to find. I would someone, somewhere has these parts but I just need to keep searching. I want to keep as original as possible.
On my oven I had the same problem, the pilot was lit but the oven would not come on. I discovered that the flame switch was not directly over the pilot light so it wasn't sending a start signal to the valve. I moved the probe over the pilot and it has since worked fine.
