what kind of pellets did you use? is it the same as you use on the memphis?
Traeger Hickory. Use them all the time on the Memphis when I don't have CookinPellets or find Traeger pellets on sale locally and stock up.
I guess how I'm seeing the problem is the Traeger pit probe is way off at high temps. The controller truly believes that the grill is at 440-450 degrees, when the actual temperature at the probe (and pretty much at the grate from what I saw in my first test) is more like 360. A medium well burger after 45 minutes at 450 'Traeger' degrees, shows that my Fireboard is at the real temp or much much closer. There's no way the real temp is 83 degrees different in that 1.75" gap between the probes in this test. My analysis of the data is making me believe this:
At Traeger probe temp of 250, actual is 225 to 250 (very acceptable)
At 350, actual is 285-300 (not acceptable)
At 450, actual is 350-370 (beyond not acceptable)
If temps were simply 25 degrees off between the probe location and the grate, I could deal with that. Set the grill to 375 to bake at 350, easy stuff. It's just that the probe itself is completely out of whack. Hopefully it's something they can fix with a firmware update or a new pit probe.
Disclaimer: This is in no way an attempt to bash Traeger. I'm just sharing the information I'm finding for others interested in the new models. I'm in no hurry to try to return the grill or anything and hope to work with Traeger on a solution. I like the grill. I like the simplicity of their mobile app, the WiFi seems stable. I LOVE that they've really reduced the temperature swings. I have also found another forum where a few others are talking about the exact same issue, so this is not an isolated problem. Not sure if that is good or bad. It would be nice to just write it off to a bad pit probe, but if it's that, they must have a bad batch and not just mine.
