BROKEN PLATE SETTER
I was just heating up the XL for an overnight brisket cook and my plate setter broke. It's not impossible to smoke without a plate setter. However, it sure is was more convenient. Grab some bolts, nuts and fender washers out of your miscellaneous parts bin (for me it's a coffee can) and bolt that thing back together.
Obviously, this is not a permanent solution, but it will at least get you by until your BGE dealer opens for a replacement.
