I've searched the internet without much success to figure out my problem. I've used my PTG 7 times now and on two occasions I found a considerable amount of smoke coming from my pellet box. No fire, but with the amount of smoke, maybe I caught it in time. Times that this has happened, it wasn't breezy and once I turned the heat down, it was back to normal. The items I was smoking weren't greasy. The only thing I could figure was the pellets were burning its way up the auger. Not sure how to correct this other than increase the temp thereby moving the pellets through the auger. I have the digital controller installed. Any ideas would be appreciated.
