I don't know anything about that specific brand, but most RV ovens I have seen in trailers as early as 1960 have a pilot light which is first lit, then it in turn lights a second larger pilot light, which in turn warms a thermocouple, which, when heated enough, allows gas to flow to the main burner. Then the main burner is cycled on and off (not modulated in size or height) by the oven thermostat. Sounds complex but it is all done for safety reasons.
If the second larger pilot goes out, the thermocouple cools and no gas can then go to the main burner, even if the thermostat says "go". When the thermostat is turned all the way to off, the second, larger pilot light goes out but the first, and smallest pilot light remains lighted unless the oven gas valve is closed or the control is turned to "pilot off".
Again, that is the sequence of all Magic Chef and Travler stove ovens I have seen. I don't know if it applies to yours.
