[Noob]

So i think it may be my therm. I didnt get to install my dial therms on the door at grate level so what i do is use a digital therm that i prop about a 1/4" above grate level. What was strange i opened the cooker after 1 hour of them in foil. I heard sizzling and the foil was already a golden color. I moved the ribs around a bit and closed the cooked. Right away the therm jumped all the way to 225°
