I should clarify something here. I and standing pilot system, pilot flame on the detection device, whether a millivolt generator or a hydraulic valve has to be correct and impart the proper amount of heat to either make the pressure or the electricity . If the mixture or intensity is wrong it will cause a trip as it should. Hydraulics are especially critical to the right temp and often have special alloys built into the pilot hood as a catalysis to make the heat for the bulb to vaporize the metal in the bulb. Often mercury.
With a Millivolt generator, one can make the flame to hot and prematurely destroy the generator. It’s always best to place a digital volt meter on the generator and adjust the pilot to the 50 or 750 millivolts as required. I’ve seen many of the 50 mv ones cooked over the years. Now if your oven is tripping of the pilot, it may be that there is too much load for the generator when the main valve comes on. Again, pilot flame off. (low or mixture)
Hopefully this will tricker some thought. But let us know the model and I’m sure we can give you further.
