Hello, on our latest trip I found our pilot goes out after the furnace runs and the camper gets up to temp and the burner shuts off. I count about 15 seconds after the fan turns off when the pilot goes out. I've adjusted the pilot screw (which was closed fully initially) all the way to loose, testing in half-turn increments, which didn't help. I can't see in the tiny (1/8") hole to see flame size or it's location to the thermocouple. I did figure out, that if I just left the thermostat on the highest setting, it just ran all night so no stoppage of the fan, nor the pilot going out and it stayed warm (surprisingly not hot, but not really surprising since a pop-up isn't sealed real well) Can I remove the thermocouple/striker/etc as I have in the attached pic, and light the pilot to see what that flame looks like and its relation to the thermocouple? I've looked online to possibly replacing the thermocouple but can't find any source, any idea of where to possibly locate? Is there any other possible issue I may be overlooking?
