Wedgewood lights but not burns

[Santaflow]

Hello,

I just got a rv ford econoline 90.

I filled the gas tank and try the furnance. Water heater works good, stove also but im haven problems with the oven.

I put it in pilot mode and use a ligter to ignite it. Works good, flame doesnt look to big. I dont see a thermocupula, instead i see a small kind of thetmocupula but I think is far from the light and under instead of in top of it. When i put higher temperature in order to run the oven ot makes a sound and the light get bigger but not much.

I waited but nothing happens. How should i proceed??

My oven is a wedgegood brand model r1740.

By other way i saw that there is a metal thing in the back of the oven but kind of loose. I checked on the guide and looks like the thermostato.

Thanks in advance.

I'm not too up on those things, but the propane valve has to see the pilot lit before it will allow propane into the main burner. I'm guessing that's not happening. Maybe a thermocouple that senses it.
