Well, I've used this unit at least a dozen times now with no problems, that is until today.
Put a couple racks of ribs in, and some apple and hickory chunks for smoke. The only thing I did diferently is add a water pan. But somehow, when I went to check on things after 30-40 minutes, the temp inside had skyrocketed! I knew what it was before I even opened the door; the wood chunks had caught fire and were burning up! I just don't know why. Obviously it was getting more oxygen inside somehow, though as I said, nothing was different. I turned off the power and yanked the woodbox out (my thumb now has a nice, white sear) and doused the flames.
Thank goodness for Todd's AMNPS! I switched gears and fired up some pellets for smoke. But it still bugs me that the wood chunks caught fire. There's only two things that I can think of.
1) The chunks were super dry, that might have been part of the problem, and
2) This is the first time I've used it outside in bright sun (it is a nice warm day today, for the first time in months.) Usually it's raining and I just point the smokestack outside of my garage door. Perhaps the sun expanded the stainless steel door and allowed for air to enter thru a crack in the door seal?
I don't know. That's all I've got.
