My new egg is about a week old. I have cooked on it every night. tonight I was trying to do pizza. I am actually having trouble getting it up to 500. I just went outside and lifted up the lid at 430 and the gaskets are melting off the grill. Yes I calibrated the thermometer on the lid so I am not at a much higher temp accidentally. I don't know what to do. I have to make pork butt starting tomorrow night. I do have the replacement gasket supplied with my egg, but I dont want to put it on if this is going to happen again. What should I do?
