Today, when I went to set the damper on my Pit Viper, the slide was stuck. There was a thin coating of dried stuff (thinner version of drip pan drippings) on the slide and connecting tube. I was able to force the slide to move and worked it back and forth until it moved somewhat freely. There had been moisture dripping from the fan when I disconnected from my last cook 5 days ago but I thought I cleaned all. Today, there was half a teaspoon or so of moisture in the fan. Doesn't bother me if it won't hurt the fan. Doesn't seem to be the place for WD-40 :ohmy: Anyone else experience this. P.S. wasn't using a water pan either day.
