I did my first BGE cook yesterday ( with about 20 guests). I definitely think I may have issues with the thermometer. I am wondering if anyone else has experienced issues with it. When I started the first 20 minutes the temp gauge was at 200. I knew it was much warmer than that. I opened it and it shot up to 750. It started working somewhat but I believe it was off all along. I have a thermapen to verify. The gauge is now saying about 760 this morning. I tried boiling in water last night after everyone left and it moved to around 0 degrees in boiling water. Any suggestions??
