Yes, what year? Did you open things up under the bed to investigate? I would think soot would be a sign burned insulation. When I had ours open under the bed I checked all the connections and found loose connections inside the transfer box.
We also had failed ground wires from broken screws that I ended up just fixing myself so it was done right.
