Like the others have said, you may have a heating element problem. However, when I did my first seasoning in my new Amerique this past December, my wood did not burn, it just smoked a bit and I was left with a charred chunk. I read on this forum that others had experienced the same problem in some CS models. Someone suggested to slightly bend the heating element up, but not touching the wood pan. Now ALL of my smokes have been a success resulting in the wood burning to ash. My personal recommendation is not to let the element touch the pan, perhaps 1/8th inch from the bottom and place the wood over the hole closest to the door.
I love my AMERIQUE! And so does my family!
Hope this helps.
