I have an issue with my new Traeger Pellet Smoker (070C). The temperature fluctuations are rather extreme. Wrong move #1 was buying it at Costco. Wrong move #2 was buying the floor model (half-price). Was wrong move #3 buying this product? I set the Temperature Control to 225. The Factory P – Value of 2 results in a low temp of 200 and a high of 320. Raising the P-Value should result in more smoke and lower temperature variances. During a several hour testing session, the P-Value was adjusted several times and ended at P-8. Despite that, the temperature fluctuates from a low of 184 to a high of 353. It seems that the high-end temp increases when the low end decreases. Averaging perhaps?? Not sure what to try next. Changing the P-Value does result in a lower temp and more smoke, but the high end temp has me concerned. Before I toss it on the scrap heap, your thoughts are solicited.
