Good save!
Foil your ribs and spritz them with som apple juice before sealing the foil - and throw them in the oven.
Now - when the Rec Tec cools - pull the grill grate, and the pan, and look in the belly of it.
My guess is that you had a flame out due to either too much ash accumulation, or similar.
when it is cool to the touch - and the ashes are cool tot eh touch - vacuum it out, and turn it back on, leaving the innards out so you can watch the hot rod in the bottom of the fire pot. It should start smoking pellets within a few minutes.
Let us know what you find. Heck - post some pics of what you find ....
