Ok Traeger guys, could use some help. I bought a new pro 34 a few weeks ago, used it for the first time on July 4th, and noticed that there was a 25 degree or so discrepancy between the Traeger readout and my Ivation digital, and also some serious temp swings, which I didn't expect, and bought this grill precisely to have a more consistent cook. On the 225 setting, it would swing between 180 and 260, consistently reading 25 to 30 degrees higher than my Ivation, and it actually quit burning after 7 hours, with pellets still in it.
So yesterday, I cleaned it all out, started over with the start up procedure and everything fired up fine. Later at about 9pm, I put on a 9 lb pork butt, and watched it until after midnight. The temp swings went from 180 to 255, and it was under 200 a good bit of the time. So I turned it up to 250 and watched it run from 201 to 300. Set it back to 225 and it's still swinging wildly his morning. I walked out and checked it at 10:30 am, 181. While I stood there watching it, it spiked to 290, this is on the 225 setting.
So I called Traeger and explained what was happening. I got 3 explanations, which all sounded like BS to me. First, the guy told me they have a new start-up procedure that could cause my issue. I reminded him it was still doing it 14 hours into the cook, so then he told me me you can't do long cooks, like a pork butt or brisket, because ash builds up in the firepot and causes the swings. I told him I know others that do that so he put me on hold, came back and told me it's a common issue called "Tunneling", where the pellets aren't being fed evenly. He said you have to keep the hopper 3/4 full and stir the pellets with a wooden spoon every hour or two...that will solve it he said...stir every hour or so with a wooden spoon. If true, I would think it would be in the operating tips section of the manual. The 9 lb butt has been on for 15 hours and the IT is only 168. My MES did better than that for 1/8 the price.
Anyone else have the same issue with wild temp swings?
