Does anyone know what might be causing the problem w/ a kettle i used (friends) this weekend? The coals were hot/ready so I spread them, put the grate on and 5 min later, added my chicken with the lid closed. I came back 20 min later to flip the chicken and the lid handle (plastic/grey) on the 22 One Touch was so hot it burned my hand. I own two kettles and have never had this happen and don't know what the issue is. Was using a normal amt of regular kingsford charcoal blue bag.
