some one posted about an off center lid the other day. Dont know if will work for everybody, but mine was off center too, and last night after makeing great ka-bobs and burning off all my hair I bumped up the heat and did a self clean. when the temp got to around 575 I gently pulled the lid over to the side that it need to go and I guess since the hinges were hot and had a little give it pulled right in place. When it cooled down and I checked it this morning it was right where it need to be. I dont know maby I got lucky,, but it worked for me.
